This will great amount of torque gained during acceleration as well as more power at the top end. Many of the cars in D1 GP use the HKS Capacity Upgrade Kit due to its high horsepower reliability. Aside from drifting, many drag racers across Japan trust the HKS Capacity Upgrade Kit. This is because parts that make up this kit are strengthened way beyond OEM standards, lighter in weight, and are ready for high horse power.

HKS recommend the purchase of the HKS 87mm Bore Cylinder Liner when installing this Capacity Upgrade Kit. This is because the SR20 block is made of aluminum and there may be a strength issue of the cylinder walls when they are bored out to fit the larger piston size. The HKS Cylinder Liner is used to gain more effective strength especially when used in high horsepower applications.

HKS RECOMMENDATIONS:
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, 87.0mm STEP2 with 1.0mm boring and honing is recommended.
87.0mm STEP2 has nickel plating, which is durable against knocking.

Using new or good condition cylinder block:
86.5mm is recommended so that 87.0mm can be used for the next overhauling.

For performance enhancement:
87.0mm in a new block is recommended. (Larger displacement will be better performance.)

FEATURES:
- 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.
- 86.5mm Piston is considered as STEP1 of 2.2L Kit. The surface treatment of STEP2 (f87.0) 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.
- MADE IN JAPAN (HKS in house production).
