Product: Capacity Upgrade Kit SR20DET 2.2L Step 1 - Forged Piston Kit
Part Num: 21003-AN008
SPECIFICATIONS:
Piston Bore (mm): 86.5
Pin Bore (mm): 22.0
Displacement (cc): 2139
Stroke (mm): 91
Oil Ring: 2 pieces type
PRODUCT NOTES:
- Boring, Honing machining: Required
- Full flow modification: Not Required
COMPATIBILITY NOTES:
- Not Compatible with RNN14.
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).

Adjustability, strength and ease of movement Review by Wesley
Cusco quality, allows for caster adjustment up front
Cusco quality Review by Wesley
Easy install, makes a good difference
Noticeable Difference, Fast Shipping Review by Wesley
Ordered this and a few other Cusco items for my ER34. Easy install, great quality
Fast Shipping, Tein great for upgraded Ride quality Review by Wesley
Great Tein Quality, Fast Shipping, Very well packaged
Perfect for GTX Turbos, where the internal wastgate is too small. Review by Philipp
The quality is typically HKS perfect.The price-performance ratio is very good and there is no other option on the market where you can increase the spring preload. It would be nice if HKS would bring another 40mm version onto the market with a smaller housing. Because it's not that easy to accommodate such a large wastgate in the engine compartment.
