Regulations
I hear a lot about penalty of vehicle height in Japan. How do you actually measure this?

When there is no one in the car, measure the distance from the most low part(such as catalyzer or muffler) to the ground. But you can exclude the accessories like aero parts or mud guard. All HKS products pass this regulation of 9cm clearance, you don't have to worry about it.

* The measurement is for a stock car. It could be difficult to have ground clearance if you have changed the height.

Can I use inner silencer and still pass the safety standards?

HKS MUFFLERS passed noise regulation without using inner silencer.

How do you measure the close noise of exhaust?

Close noise of exhaust is measured in a certain condition of engine at a certain RPM.

1. Set the sound measument device at a 0.5m from the muffler exit of 45 degrees.
2. The engine RPM for the measurement has to be 75% of what the engine can produce.
3. From the #2 situation, put the gas for 5 seconds with no pressure for RPM and release the pedal, and measure the sound while the RPM get to the idle RPM. At this measuremnet, the highest sound is the sound of the test result.

* This is a diagram of the testing.

kisei_img_03-2.gifThe Lancer Evo's max power is at 6,500, so set RPM at 4,875 wich is the 75%

 

 

 

 

kisei_img_03-3.gifPut the gas for 5 seconds at the 4,875RPM and start to measure the sound. After 5 seconds, take the foot off from the pedal and check sound until idling.

Structure & Warranty
What's the difference between a normal muffler and a HKS muffler?

Normal mufflers are designed only to have efficient exhaust capability. HKS mufflers and pipe layout are designed to support the best performance of a car. 
The shell part of the normal vehicle is made to decrese the sound of exhaust gas but HKS shell is designed for a cool and sporty sound.

What is the HKS warranty for the products?

HKS provides a warranty to the original purchaser of HKS exhaust systems against defects in materials and workmanship for a period of one year. The warranty is available only for vehicle-specific exhaust systems. Metal catalyzers, front pipe, exhaust manifolds, and center pipes are not covered.
(For more details, please go to the product warranty site.)

I bought a muffler about 2 or 3 years ago. And the sound of the muffler got bigger than before. Is it normal?

The muffler passes hot air, so over the years the quality of the mufffler sound will drop and will have a bigger sound. 
Muffler is a consumable good. That's why we are using the advantex glass wool for the best and long lasting mufflers.

What is the cylinder in the middle of the pipe of HKS MUFFLER series?

That's called a " SILENT CHAMBER (ex: ES WAGON 409)".
A stock car, mini van or wagon tend to have a muffled sound when you change the muffler, and the silent chamber make this muffled sound go away.
As you can see below, silent chamber can change the frequency and reduce the bad sound from the muffler.
We test and analyze the each vehicle's sound and make a best silencer. However by putting this chamber will not effect on the exhaust presure and the beauty of the car.

For sport users
I am driving a NA car and I was looking for a muffler that makes sounds like NA, does HKS have such a muffler?

The HKS SUPER SOUND MASTER MUFFLER is perfect for you. It has a cool high pitch sound and at a low pressure and has a quiet sound.

I changed the sport turbine kit and I am looking for a muffler for my big powered car. ButI don't want a too loud muffler. Do you have such a muffler?

Yes we do. HKS SUPER TURBO MUFFLER is a low pressure and lower noise muffler.

I often go to a circuit for driving. I want an ultimate muffler for ultimate car driving. Does HKS has a perfect muffler for me?

The sport muffler made fully of titanium (one of the lightest muffler in the market) and ultimate straight design muffler, HI-POWER SPEC R, is HKS' top level muffler. It is developed to attack in the circuit. This would be perfect for you.

I want to buy a sport muffler but I can't afford an expensive one. Does HKS has a reasonably-priced sport muffler?

Yes, the HKS HI-POWER 409 is a good and reasonable muffler. It's a HI-POWER series high-quality muffler for an affordable price.

I think it's very important to have a good performance muffler, but recently the regulations have gotten stricter, so I want a muffler with quiet sound and still has a good performance. Does HKS has such a muffler?

The SILENT HI-POWER, as the name indicates, is a muffler with quiet sound and still has performance power in a good balance.

I usually use my car to drive in the city and I don't need a sport muffler but I want a cool looking design and good performance.

ES PREMIUM is a cannon ball type design muffler and LEGAMAX PREMIUM is the clean and stylish tip design muffler that are very cool and beautiful looking. It's perfect for city driving of a normal vehicle.

I have Skyline GT-R (BNR34) with the RB2.8L engine and installed GT2530KAI, Airflow Less Adaptor, V-Cam, etc. The engine output is over 600PS. The exhaust sound is very noisy, so I am worried if it is bothering my neighborhood. Is there any exhaust system

"2 Stage Exhaust System" is recommended. 
Usually, as the tuning level is advanced, implementing "silence" and "high power" together may be difficult. 
But, the switchable valve equipped with this exhaust system controls the exhaust path depending on the engine RPM 
so the exhaust system can withstand high power maintaining silence at low speed.

 

sport_img_01.jpg

I have a sports car and am looking for a exhaust system made fully with titanium, but it is very expensive. Is there an affordable lightweight exhaust system?

"Hi-Power SPEC-L" is recommended.

Pipe plate is 0.8mm thick and silencer outer plate is only 0.5mm of SUS304 material. This super lightweight exhaust system is comparable to a full titanium made. Also, it has an efficient exhausting ability and cool sound. Only HKS can make this kind of high engineering exhausting parts.
*Subaru WRX Sti: The weight of this SPEC-L is only 10.5kg which is -53% of the 22.4kg stock exhaust system. 
The lightweight exhaust system has many advantages such as better exhaust efficiency, acceleration/deceleration performance improvement, reduction in a brake load, more accurate turning traceability by reduced inertial weight reduction, etc. Replacing the exhaust system with this product changes the driving drastically.

For Mini Van & Wagon Users
I own a mini van and want to have a muffler that fits to my van which already has the aero and the aluminum wheel and still has quiet sound. And still it has to be a good looking muffler. Do you have a muffler for me?

LEGAMAX PREMIUM is what you need. It fits great for a van with the aero and aluminum wheel installed. And of course it has passed Safety Standards regulations for the sound level.

I am looking for a muffler that has sporty performance features and sound for my wagon. Does HKS has a cool sporty muffler for a wagon or mini van?

We have develpoed a new cool and stylish design of muffler ES PREMIUM or ES WAGON for a users who are looking for the sportiness in their muffler.
* We also have a low cost muffler ES WAGON 409

I want to change the muffler for my car. And I want something with decent performance and looks good and cheap! Am I asking too much?

No, not at all. We have exactly what you want! The LEGAL MUFFLER is what you are looking for. Its tip is designed for the each vehicle and have a good feature for a low price.
* There is also LEGAL MUFFLER SPORT.

Suspension

Structure
The Single tube type is for racing specification, why does HKS make it for street specification?

HKS' goal of suspension development is to have a perfect damping force in every situation of the driving environment. That's why we make our suspension in a single tube model. It's true that the single tube type was born in the racing world. It also means that single tube type is best for the driving an automobile, because the racing world is the toughest driving environment and this has been proven to be the best type for it. That's why HKS choose the single tube type for our suspension. 
However they are a costly structure to produce and difficult to design. That's why many other suspension makers gave up on this type of suspension production. But HKS has everything from designing to the packaging which make it possible to produce great products at a lower cost.

I heard that the single tube type can not have enough stroke volume compared to multi tube type. Doesn't that mean it's less comfortable than the multi tube type?

It is true that the multi tube type has more stroke volume than a single tube type, but It doesn't mean the bigger stroke volume has a better suspension performance. The single tube type has two rooms of oil and gas and the piston move inside the oil chamber which will produce an ideal damping force. The cylinder is in the outside of chamber that the oil will last long which results in a longer life of the suspension.

 

kouzou_img_01.gif

Is it true that the single tube type is less durable for outside impact than the multi tube type?

It is true that the single tube type is less durable than the multi tube type. However the roads in these days are paved and it's almost never happen something that might cause the suspension to break. And also HKS make the suspension with very hard materials that we are sure HKS suspension is safe to install. 
Then what the impact from side? Will it not break by the impact from the side?
Single tube type is an inverted type. It can be layout for stronger for the side impact. Anyway for multi tube type, it can not.
The single tube type needs very detailed work in a seal. This kind of precise work produce a strong and safe suspension.

 

kouzou_img_02.gif

What is the piston valve? And how can it be evaluated?

Piston Valve is the part that is in the tip of the piston rod. It will move up and down while driving and the oil will will flow into the piston and the the hole that oil flow called orifice. The piston valve is the heart of the damping. So when the damper get a force from the road, the piston will go up and down inside the cylinder and it will have a damping force by the flow of the oil. 
By setting the volume of the pressure, oil flow and valve timing make the controlling of the oil flow. And this is the most difficult step in developing a suspension. There are all different setting for each situation like D1 drift, street drive, circuit race, drag and etc.

 

kouzou_img_03.gif

Why is it a large duct? How will it affect the damping force?

We can change the area of the piston which will affect the flow of the oil. It's very important to control the oil flow. Making oil flow big will control the damping force more precisely and safely. However it doesn't mean the bigger oil flow is better. It all has to balance with other parts and settings.

For Sport Users
This is my first time buying a sport suspension. Do you have a suspension that let me have a low vehicle height and still fine for city drive?

We recommend our new MAX IV GT. It will have a adequate vehicle height and have a comfortable ride in a city. But still when you are driving on a winding road, it will have a firm and smooth feeling.

I am looking for a suspension with high performance for a high grip radial on the circuit. However this type of suspension is very stiff and uncomfortable to ride in the city.

MAX IV GT will be a good suspension to transfer the information from the tires. It can be used for both the circuit and street driving.

I used to be a hardcore tuning maniac, but now I have a family and can't tune up much. I bought a new lxurious car and want something for my new car. Do you have one for me?

MAX IV GT is very luxurious. We have set each suspension for each vehicle for the best performance and comfort.

I want to be a D1 driver in the future and I am looking for a good suspension for the perfect drift.

You need HKS HIPERMAX D' NOB spec! This will help you drift like NoB! Usually drift suspensions are just hard and slippery rear. But HKS HIPERMAX D' NOB spec push forward while you are drifting and respond sharply when you turn the handle.
* HKS HIPERMAX D' NOB spec make it easier to drift for everyone.

For Mini Van, Wagon & Compact Car Users
When I was single I used to tune my car but now I am married and can not tune very much. However I don't want to ride a normal mini van. Do you have a suspension for me?

HKS HIPERMAX S-style C  is for the mini van or wagon that lower the vehicle and still give you the comfort driving feeling on the street. And you can adjust the height in 30 steps with HKS HIPERMAX S-style L.

 

I have a compact car and want to buy a suspension. Do you have a suspension that is good for a compact car and inexpensive?

HKS HIPERMAX S-style C is a reasonable suspension which can be adjusted for the height, too. It won't make a fluffy feeling like the stock suspension.

I want to lower my new wagon with aero and wheel installed. But I don't want to lower it too much to damage my aero or wheel. Do you have a perfect fit suspension for my wagon?

HKS HIPERMAX S-style X is designed to have both cool looks of lowering and the comfort driving feeling. This is what you need because we made this specially for the wagon with aero and wheel installed. This is ultimate suspension for a lowered wagon.

I owe a compact car and want to purchase a suspension that make my car look cool. And also I want to drive fast with a sport car in the corner. What HKS suspension should I get?

HKS HIPERMAX S-style X is designed to have both cool looks of lowering and the comfort driving feeling. This is what you need because we made this specially for the wagon with aero and wheel installed. This is the ultimate suspension for a lowered wagon.

Sound
There is a strange sound coming from the suspension.

* Please go to the shop or specialist for a check or repair. Do not attempt to do it yourself.

Overhaul & Specification change
I am using HIPERMAX damper and recently it doesn't respond well and is making some sound. Should I do the overhaul?

Yes we recommend the overhaul. It's also recommended for overhaul when you feel a stroll in a lane change on the highway or oil leak. Suspension is a comsumable product, it has thousands of times of stroke and under high heat situation in 100km drive. We think overhaul is very important and we have high support system of overhaul. Please use our overhaul for a safe and great driving experience.

Warranty
SUSPENSION is a very expensive part of tuning which usually costs more than $800. I am worried that the suspensions that I buy will be defective or break after a short period of time. What is the HKS warranty like?

HKS provides a warranty to the original purchaser of HKS suspension against defects in materials and workmanship for a period of one year. The warranty is available only for the damper assemblies and springs. Dust boots, upper plates, pillow-ball, and hardware/accessories included in a kit are not covered.
(For more details, please go to the product warranty site.)

Vehicle Height Adjusting
About all length adjustment type damper that the tire coming out

When using tire wheel at the end of the fender (Tsuraichi) for the stock damper or stock type damper, the tires might come out of the fender because the all length adjustment type damper measurement is too big for stock damper. After installation, it tends not to fit well for negative direction of the chamber. There were problems for these automobiles; AZR60(NOA/VOXY), JB5/7(LIFE), C25(SERENA), GD1(FIT). Usually if a vehicle is lowered, the chamber will not attach to the negative direction, and the tires are move into the fender. However there are different situations such as above vehicles, so please be careful when setting.

About EVC
What does the offset means? Will the offset make the start-up boost?

Offset can adjust the lag for the target boost, but at the same time, it will cause a change at the boost start up. To increase boost by swing control for older vehicles, the value was lowered, but EVC V, increasing the value of both swing control and poppet control will cause high boost and lowering make it low boost.

The "Warning" is not working even though high boost is on the peak hold than the warning value setting.

Sometimes, the boost instantly goes up like an overshoot passing the warning boost setting because of the boost start up characteristic. The Warning system will work after a sudden time span of pressure occurred which is set in the EVC.

Recently, I see error messages.

Please check the relay harness or power supply harness. And be careful with the power supply position or ground wire point of the power supply harness.

I set the boost and used to drive fine, but now the boost is not working correctly as I set.

The EVC boost control could work incorrectly if the vehicle changed a new part. If the boost control fails too much, please reset the EVC and do the initial setting again. If you didn’t change any parts, the pressure leakage by pipe dislocation or slit could be the cause.

Why are there 3 modes A, B, C? Which one of the A/B/C is high boost?

There are 3 modes to set 3 types of boost. For example you can set A for normal boost and B for middle boost and C for high boost.

What is the Scramble boost?

Scramble boost is an automobile system used in a race or competition to have a boost of power for a short time. Scramble boost will have more boost pressure to the normal boost setting. Therefore you need to tune the engine to endure the scramble boost.

Can I lower the boost with EVC?

You can't set the boost lower than the vehicle's lowest boost setting (boost pressure setting of actuator and wastegate). However if a stock vehicle installed a boost pressure solenoid, sometimes, it can have a lower boost than a vehicle before it install the EVC when the EVC is OFF.

Can I put EVC in my KEI-car? Can I put it in my diesel car?

If your car has 12V actuator or wastegate and turbo with boost pressure control, you can use it.

Can I put it on my SILVIA? Can I put it in my SKYLINE? Is there any documents for piping work for each vehicle?

Please refer to "Swing valve type setup" for more information.

Can I buy just control unit? Can I buy only valve unit?

No we don't sell separately.

I have a lot of overshoot. Can I control it with EVC.

By changing the offset setting value or MAP function, we can have some difference, but we recommend fixing the pipes too. It's very effective with shorter pipes, especially with φ4 hose. Also, if you take the φ6 chamber pressure from surge tank, it will cause the overshoot. If all the settings are correct and adequate and still have the overshoot, then it's just the vehicle's characteristic.

I am having a hunting.

Please reset the sampling time. If the situation doesn't get better with sampling time resetting, please use better φ4 hose which can have precise surge tank pressure, or maybe you need to use the orifice or make the φ4 hose a little longer which could prevent the hunting.

I bought EVC because it has maximum of 300KPa, but even though I set to the maximum level, boost does not go up.

It could be because of the vehicle specification. The boost would not go to 300KPa because of the change in the heavier wastegate spring or the capacity of the turbine or the engine.

I am having a boost cut and knocking.

If you make the higher boost setting than the normal, the vehicle's boost cut will happen because of the fail-safe system. In that case, you can use boost cut disabling device, such as FCD to have higher boost setting. But if you don't set the parts such as fueling carefully for your vehicle, it can cause a knocking or detonation and damage the engine.

The boost value of 2nd gear and 4th gear is different.

A lower gear driving and a high gear driving has a different driving mass. Therefore there are different boost value. Please set the boost with EVC at a high gear such as 4th.

I can't control the boost. The boost doesn't go up.

Please check the pipes and exhaust bypass switch for controller. If you set the same for normal max boost and normal boost for initial setting, it can't control the boost because it can’t recognize the correct boost characteristic (you can check the initial boost setting value with EasyWriter). If the normal max boost setting value and initial boost setting values are the same, then please reset the EVC.

After I set the EVC, the boost doesn't work as I set it.

If there is a specification change for the vehicle, please check the normal boost and reset the boost in each A/B mode.

The meter value of the device I bought and the EVC is not same.

Is the place of the pressure check is the same for both EVC and the meter? Depending on the devices, if the difference of the EVC and meter is within the 10KPa, it's a common difference.

Do I have to use the air filter?

To prevent the oil from entering the valve unit, you want to use it. And also, if you see more dirt, you should change the filter.

I set the boost at 130KPa with my EVC but boost hangs to the 100KPa. Can I prevent this?

Because of the certain specification of vehicle, turbine or actuator characteristics, the boost sometimes hangs at a high RPM. You can restrain some of the boost hang with EVC, but if the situation doesn't improve, you need to change or strengthen the actuator or other parts.

The surging occurs.

You see more and more of this in recent years for turbo automobiles. However you can set the MAP function to prevent surging from happening. It could happen because of the certain specification of vehicle, turbine or actuator characteristics and etc. Then you might replace or modify parts to fix it.

I can't see the monitor clearly. The display is pale.

The Monitor looks best from the straight angle. The display could be pale because of the angle. Please change the angle of the monitor or position for a best view.

I can't change the configuration.

The "Data Lock” could be on. Please turn the data lock off. Follow the instruction in the manual.

The boost is going too high.

Please check the exhaust bypass selection switch is correct with vehicle. Also check the short wires, snapping, miss-wiring, etc.

Display unit, valve unit, harness connector are damaged.

Please visit your nearest dealer for check and repair.

I have broken the harness, can I repair it?

No, you can't repair the harness. Please purchase the EVC harness in the option parts.

I want to use the MAP function, but I can’t get the RPM well.

・Please check the wires and cylinder.
・If the RPM signal outputs to multiple tuning parts, the RPM signal voltage weakens and that EVC can't catch signal.

I want to use the MAP function but there is a problem with the throttle open.

・Please check the wiring location and all-open or all-close throttle setting.
・Please check the earth wire. Do not modify the earth wire and make sure to do the body earth.

I did the wiring but it doesn't display RPM or throttle opening.

・Please set the MAP function. It will display signals in the MAP function with Map axis.

The scramble boost is not working.

・Please check the scramble time setting. If the scramble time setting is too short, the scramble could be canceled before the boost goes up.
・The vehicle side setting could cause the boost to stop. Please check with A/B setting for target scramble boost.

What's the difference between stepping motor and solenoid valve?

Solenoid valve has only 2 conditions, "ON” and "OFF”. The interval of the ON and OFF controls the boost. In contrast to solenoid valve, stepping motor can adjust between ON and OFF. This can control boost more precisely.

What can the EasyWriter do?

You can set or change the each values faster and precisely, can do more precise setting with the MAP function and can use the logger function during the boost setting.

Speed Limit Defencer

Speed Limit Defencer
Is there any adverse effect by installing SLD such as fuel efficiency?

It depends on stock ECU program condition, but basically there is no influence. There was no case of engine failure because of the SLD usage.

What is the SW setting in the manual? What do I have to do?

It’s about switch in the SLD. SLD has to set the right switch for the your automobiles.

I did all the SLD installation, wirings, switch setting and still can't disable limiter.

If you set the switch after IG-ON, the setting might not be executed. Please make it IG-OFF and try again.

I have bought and installed the SLD TYPE II and my AT car seems to have some problem.

Please check the wire settings of solenoid A and solenoid B, if it's ok, it might be the swtich's setting. Please check for these settings again.

There are no wires in the place where the manual indicates!

For some cars, ECU is in the engine compartment. Please check the manual and do the wiring to the ECU.

Where should I position the device? Is the device ok with high temperature? (For some cars)

Please set in the ECU box with the double sided tape. If you put the device inside the ECU box, the high temperature will not be any problem.

Can SLD pass the Automobile inspection (Japanese)?

Yes you can. Please follow the traffic rule and drive safely on the road.

What happens to the stock meter or a retrofit meter, how will it display if I install the SLD? Can it show 180 km/h over?

1. For SLD type I/II
The stock meter will display as much as it can. For installing a retrofit, please wire with sky blue color wire if there is one, and if not please wire to the white color line.

2. For SLD type III
It will only display from about 170 to 175km/h for SUBARU cars and the retrofit meter type which uses CAN communication signal such as OBD II for vehicle speed display. Also, if you connect the CAC or turbo timer to the speed signal wire of the option coupler or navigation, it will display 180 km/h over (including SUBARU).

The speed wire is connected to the navigation, what can I do?

Please connect SLD between the position where the navigation is wired and ECU.

(For some Honda automobiles) I have installed SLD but meter doesn't work. Also my car doesn't go faster than 165 km/h.

1. If the meter is not working; 
Probably the vehicle speed signal wires of input/output (white/yellow) are set wrong, or power supply or ground wire connection might be the cause of the problem.

2. If the meter stops at 170 to 180 km/h;
Please check the a wiring diagram for HONDA and setup the SLD sky blue wire. (Check the table below)
* Please contact the shop where you purchased product or HKS dealers for more specific information.

(Refer to wiring diagram for these HONDA automobiles.)

VELOCITY ADVANCED COMPUTER

Does the shift feeling change after installing VAC? Is it readily noticed?

VAC starts functioning at 180km/h or over; VAC's unique AT control is performed. Under VAC control, shifting gears becomes smooth with high response without power reduction which can be experienced during high speed cruising.

Is installation difficult? How I connect the wires?

Installation is not really difficult since wiring is simply done by connecting wires using couplers. However, it involves removal of a negative cable of a battery which requires the initial settings for the power window, back guide monitor, etc.(See the manual for more details.) Also, modification of the ECU box is required (except for VAC type S). It is recommended to ask a professional for installation

Where the main unit should be mounted?

Install VAC type S to inside the ECU box where is located in an engine compartment. Other types must be secured to a foot space part on the passenger's seat side by installing the harness and pull it from the ECU box where is located in an engine compartment

What are possible factors of the malfunction such as the CEL, engine stall, etc

Make sure if the harness couplers are tightly inserted. Improper installation may cause malfunctions

Turbo

What is the turbo charger?
Turbo charger is...

img_01.png

If you think it's broken...
Self-Service Steps

Most important thing to do is to check turbo charger before take it off from the engine. Most of the time, there is no problem in the turbo charger and find it difficult to assess the problem after you take off the turbo charger. 
It's usually much easier to find out the problem if you think the turbo charger have a no problem.

Please be careful to check the list 1 to 3 below. You should not think the problem is from the turbo charger at first.

White smoke (Oil leakage)

If the oil doesn't flow back to oil pan and cause a leakage, the white smoke from the muffler will come out.

I.The rise of the pressure in the engine(crank case)
The center housing of the turbo charger is in a negative pressure to prevent from the oil to leak. However the blowby-gas that occurs by the piston ring because of the friction and not proper exhaust of the blowby gas cause the oil leakage from the turbo when it's a high pressure in the crank case.
And also the oil used in the turbo does not flow back smoothly to the oil pan will cause a oil leakage.
Simple Inspection Method
(1) The white smoke will go away if you take off the oil exit, level gauge and blowby hose.
(2) When idling and open the oil-feeding hole and see if the air doesn't go in(you can check with smoke near the hole).

If there is the situation of (1) or (2) it could probably mean the pressure of the crank case of the engine gets too high. If the engine is normal, it will intake to the blowby to the engine by using the negative pressure in the crank case of negative pressure and the pressure in the turbo is also negative pressure, so the oil will not blow out of the turbo. 

Conceivable cause
(1) The friction of the piston ring, cylinder and valve guide.
Can intake the blowby gas because of the galling, combustion gas leakage. The vehicles with long distance of driving must be cautious. 
(2) Blowby gas or PCV valve clog or defection.
The blowby gas doesn't inhaled properly because of the hose or the head cover of the connection part clogged or the defect of the PCV valve that doesn't boost in the crank case.
(3) Blowby hose is wide open or oil catch tank is defect.
You should be careful not to wide open the blowby hose. It could not flow properly in the oil catch tank of the blowby gas because of the length or curve of the hose.


* 1. PCV (Positive Crankcase Ventilation) Valve

PCV valve inhales blowby gasin an idling and also work as a orifice to control the too much inhale of the blowby gas by engine brake or too high negative pressure of surge tank.
Moreover, if the surgr tank get to be the normal pressure by the boost, the crank case pressure lower by flowing by the PCV valve as clack valve and close it to release the gas from main to the crank case.


Confirm the PCV movement
Check the PCV flow the air into the one direction

・Clean with brake cleaner
・Change if it doesn't work after the cleaning
   
Make sure the the hole is clear for the blowby hose installation partof air cleaner side
The back of the connector of hose is sometimes closed with sludge.

・Confirm the hole with wire
・If it's clogged, open with wire of air blow
   
Make sure the PCV connector is clear
As you can see in the picture left, sometimes the hole is clogged with sludge 

・Confirm the hole with wire
・If it's clogged, open with wire of air blow

II. Clogging, curving and collapsing of the oil return (drain) 
It will have oil leakage because the oil in the turbo that doesn't return to the oil pan. Also the sludge in the exhaust manifold and wastegate will cause the not a smooth oil flow.


III. Excessive oil supply
Make sure to be φ0.6~1.5m for oil supply line of orifice to control the oil supply. The size of the orifice different from the engine type and turbo type. Set the oil pressure for maximum of under 2.5kgf/cm2 of turbo entrance with the orifice if it's ball bearing type.(minimum of more than 0.7kgf/cm2). The oil volume of the dress hose exit is 800cc/min.  


IV. Excessive Engine oil supply
This will not have smooth oil flow to the oil pan and will have oil leakage, too. For a sudden stop or inclined driving might cause the high oil level and defective in oil return.

V. The oil will be sucked into the intake side because of the clogged air cleaner.
It doesn't cause as the problem because the tuning car usually uses stick out type air cleaner. But if it's blowby gas suction, be careful not to mistake with the oil.

VI. The oil will be sucked out to the exhausting side for the big front pipe & catalyzer-less.
Need to be careful because sometimes the tuning car has a big front pipe and catalyzer-less. Usually, it smells very strong of burning smell of oil with white smoke when the oil leakage occurs in the exhaust part.

VII. The mistake of the oil left over from the past.

Sometimes the oil leakage happen before in the intercooler or muffler could be mistaken for the oil leakage.

Turbo charger structure is sealing the oil by rotating. Therefore when the lower RPM such as idling has higher possibility of oil leakage and also once it started to leak there will be a drain that keep the oil to drift. We don't recommend for a long idling. If there is no problem from I to VII, it could be the engine problem. Please check the engine. And if there is no problem in the engine, please check the turbo charger.

No power (the boost doesn't go up)

I. Boost pressure loss (turbo charger, intercooler, throttle and intake manifold)
It could be the air leak from the joint hose between the pipes or it open by too much of the stock or other maker's boost pressure. There could be leakage from the surge tank or intake manifold.

II. Blocked or crushed part of the intake system
If the air cleaner is blocked or the rubber hose used for suction in front of the turbo charger could cause to crush for the negative pressure by the boost. And also there could be waste between the turbo charger, intercooler and throttle.

III. Throttle valve
It can't have the boost pressure if the throttle valve is fully open in some reason.

IV. Malfunction of the swing valve or wastegate valve.
Boost pressure will not go up if the swing valve of the boost pressure control or wastegate valve is open too much. The seizure of the valve, defect actuator that is to activate the valve and defect in the air pressure control for the actuator. Also check the movement of stock boost control solenoid valve and the area the hose is. And check if there is an orifice or not. Another case, even the actuator or the wastegate is working fine, if the spring is weak, it will not have the boost up because the valve open for exhaust pressure.

V. Blocked exhaust system
If there is block for the Exhaust manifold, turbo charger, extension, front pipe, catalyzer, and muffler the boost pressure will not go up.

VI. The leakage in the exhaust system
If there is gas leakage for the exhaust manifold or turbo installed flange, the boost pressure will not go up. You will probably notice when this happen because of the leaking air sound.


If you don't find any problem of I to VI, it could be the problem of engine. If you find no problem in the engine, please check the turbo charger.

Strange Noise

I. Boost pressure loss (turbo charger, intercooler, throttle and intake manifold)
It could be the air leak from the joint hose between the pipes or it open by too much of the stock or other maker's boost pressure. There could be leakage from the surge tank or intake manifold.

II. Blocked or crushed part of the intake system
If the air cleaner is blocked or the rubber hose used for suction in front of the turbo charger could cause to crush for the negative pressure by the boost. And also there could be waste between the turbo charger, intercooler and throttle.

III.Blocked exhaust system
If there is block for the Exhaust manifold, turbo charger, extension, front pipe, catalyzer, and muffler the boost pressure will not go up.

IV.The leakage in the exhaust system
If there is gas leakage for the exhaust manifold or turbo installed flange, the boost pressure will not go up. You will probably notice when this happen because of the leaking air sound.You will hear the big blow sound when it starts to open if the wastegate exit is deformed or fully open.

V. Strange noise of the pipe

If you don't find any problem in steps I to V, it could be the problem of engine. If you find no problem in the engine, please check the turbo charger.

Checking the turbo charger
Checking the vehicle

Take out the intake pipe of the turbo charger and turn the rotor with your finger. Be careful not to turn the engine on.

I. If the rotor turns:
Wheel could be broken. The compressor wheel or turbine wheel is deformed or broken. Sometimes you can see it without taking off the turbo charger, but sometimes you can't see it if you take off the housing. If it's deformed or damaged, you can hear a weird sound. If you keep this for a long time, wheel and housing will interfere because of unbalance and finally the turbo charger will break down. So if you hear the sound of a weird sound, take the turbo charger and have a check. Also if the bearing is turning in friction, the rotor is not properly moving. For both conditions, you need to take it off and have an inspection. 

II. If the rotor is not turning:
The turbo charger rotor is stuck or interfering. The rotor will have lock or malfunction of turning by the seizure the ball bearing. Also the long term oil leakage occurs, it will get carbon because of the heat of the turbine and cause the rotation malfunction by the turbine and the rotor. There a case where the some waste stuck in the turbine and housing or shroud that causes the lock. In this case, you can confirm with your finger and don't have to take off the turbo charger. However turbo charger is broken so take it off and have an inspection.

Taking off the turbo charger for checking

When taking off the turbo charger, be careful to confirm the list below as carefully checking where the problem is. 

I. Check the unusual bolts, nuts and hose.
II. Check for contaminant (usually caused for turbo charger damage)
III. Check for Heat discoloration
IV. Check for oil or coolant water for leakage or bad contamination


If you notice above matter, don't disassemble and bring the turbo charger to the shop where you purchased it.

Cause of the turbo charger failure
Failure in the oil supply (dirt, dust, insufficient oil or breakage of oil film)

If a dirt goes into the turbo charger, it will be a clearance failure and will damage the shaft receiver and bearing surface.  Also there is a orifice from φ0.6 to 1.5 in the turbo charger oil supply line. In this orifice will have a dirt or sludge stuck into and have the oil film breakage and seizure.

These are the cause of the dirt get into the oil:
・Degradation of the oil (sludge) 
・Degradation, damage or oil filter stuck
・Malfunction of the oil filter bypass valve
・A dirt mixed in at oil change 
・Metallic fragment or broken piece at the engine breakage
(When engine blow occurs please overhaul the turbo charger)
・When using liquid packing or seal tape, part of them could get in the oil line while turbo charger change.


Cause of the oil film breakage: 
・Degradation of the oil
・Insufficient oil
・Sudden acceleration when there is not enough oil in the turbo charger
・Low oil pressure because of the oil pump defect
・clogging of oil strainer


And etc.

Object threw into the wheel

The wheel blade will be damaged if the an object go into the intake or exhaust wheel. And if you keep drive in that condition, the shaft will be broken because of the unbalance rotor which cause bearing seizure.

The cause of the object fly into the intake system
・The nut that tighten the impeller that's in the air cleaner or suction pipe will sucked in. 
・Assembled while some object are still there like washer or waste.


If an object is something hard like a nut or a rock, the blade will be wrecked or cut. Or if the object is soft the blade will be deformed to the back. If it's sand or dust, the blade will be wore out.

The cause of the object going into the exhaust side.
・The piece of engine parts(plug, piston, ring, etc.)
・Things that forgot to clean.


The lock could also happen by something get stuck from the engine to turbine blade and housing or shroud. 
If something go into the exhaust side, the engine could be damaged. In this case you need to inspect the engine first.

Exhaust temperature excess

Sometimes while driving or right after you stop a car, the turbo charger can get damaged by the high heat. If you stop a car after driving, the lubricant and coolant oil also stops. This will cause the oil film breakage of the still running shaft and bearing and also the high heat of the turbine housing will transfer to center housing which cause the sludge.(heat soak back) If this sludge increase, the oil passage will get narrow and cause an even higher heat. Later, the sludge will get granular carbon and damage the bearing, seizure of the bearing and breaking the shaft. It's better to have an idling time after a drive. And if you can't have an idling like at a race, making the cooling system for center housing will prevent this problem.
If the temperature of the exhaust is too high while driving, there could be interfere between turbine housing and turbine wheel because of the deformation. Also it could cause a crack of the turbine housing and carbonized of oil. When setting please check the fuel-air ratio and also the exhaust temp.

Causes of the temperature rise:
・Unusual A/F
・Unusual ignition timing
・Exhaust system clogged
・Unusual engine management system including the stock ECU
