Fitment:

  • 1991 – 2002 SR20DET

Features:

  • Displacement of SR20 is increased from stock 1,998cc to 2,139 cc.
  • The larger displacement will increase torque. It enables to be used with large flow capacity turbines.
  • Step 2 87.0 is 2,164cc
  • 86,5 piston is considered as step1 of 2.2L kit. The surface treatment of Step 2 (87.0) is not done for Step1 to achieve the affordable price. This kit is also recommended for overhauling purpose. Feel the power of 2.2L.
  • Although it is Step1, it is forged pistons. Forged connecting rod and forged crankshaft are the same items as Step2 that means the maximum target horsepower is the same.
  • 87.0 piston is Step2. It has nickel plating, which is more durable against knocking, on the piston top and over coating, which reduces friction, is on skirt portion.
  • Made in Japan (HKS in house production)

Using an used cylinder block

Due to deformation, with 0.5mm diameter boring and honing may not be able to have accurate circle bore. (Same for other engine models.)
In case bore is not accurate circle, pistons cannot be installed accurately. Therefore, φ87.0 STEP2 with 1.0mm boring and honing is recommended.
φ87.0 STEP2 has nickel plating, which is durable against knocking.

Using new or good condition cylinder block

φ86.5 is recommended so that φ87.0 can be used for the next overhauling.

For performance enhancement

φ87.0 in a new block is recommended. (Larger displacement will be better performance.)
