キャパシティ アップグレード キット FA20 2.1L KIT キャパシティ アップグレード キット FA20 2.1L KIT LOW COMP

High boost tuning in the era of direct injection engines!

The low compression type FA20 2.1L Kit is available for high boost tuning.
Upgrading with forced induction is very common for the FA20 engine tuning.
HKS has developed a highly durable low compression piston required to move onto the next tuning level.

Features

POINT-1 Piston
  • Forged material improves durability.
  • The cavity is designed in piston crown to optimize the atomization of fuel during injection.
  • 3D Piston crown design to optimize tumble flow.
  • The piston is recessed to match high lift HKS camshafts.
  • The compression ratio range is widened depending on the gasket's specification.
  • Molybdenum coated pistons reduce friction.
POINT-2 Connecting Rods
  • Cracked connecting rod is chosen for the long stroke. The big end size is designed to omit modification of the engine block.
    (Nissan genuine bearing for RB26 and SR is required separately)
  • Highly durable I-beam and cracked connecting rod are included. The connecting rod bolt size is optimized.
POINT-3 Crankshaft Stroke 90.0mm
  • The crankshaft is made from forged materials.
  • Bespoke pin journal size is employed.
