HKS Capacity Upgrade Kit for FA20 Low Comp

HKS have developed the Capacity Upgrade Kit for FA20 Low Comp for high boost tuning. 

HKS have developed the Capacity Upgrade Kit for FA20 Low Comp for high boost tuning.  Since upgrading the FA20 with forced induction has become common, HKS decided to take it to the next level.  This kit includes Forged Pistons, I-Beam Connecting Rods and a Forged Crankshaft.  These kits are also available in Step 1 package and a Step 2 package.  Step 2 includes stronger Connecting Rods.

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

  • STEP1
    • 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.
  • STEP2
    • The thickness was optimized by strength analysis. The weight increase was minimized, and the strength was increased by approximately 30%.
    • I-beam shape was selected to increase the buckling strength.
    • The ideal shape was realized, and the fracture origin on the surface was eliminated by forged billet manufacturing. To improve fatigue strength, strong shot peening treatment is carried out on the surface.
    • The optimum heat treatment for chrome molybdenum steel was carried out to improve both strength and toughness.

POINT-3 Crankshaft

  • Stroke 90mm
  • The crankshaft is made from forged materials.
  • Bespoke pin journal size is employed.
