■Feature

Displacement of SR20 is increased from stock 1,998cc to 2,139cc.
The larger displacement will increase torque. It enables to be used with large flow capacity turbines.
*STEP2 φ87.0 is 2,164cc.

 

φ86.5 Piston is considered as STEP1 of 2.2L Kit. The surface treatment of STEP2 (φ87.0) 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 piston. Forged connecting rod and forged crankshaft are the same items as STEP2 that means the maximum target horsepower is the same.
