Wiseco Nissan SR20/SR20DET Turbo -12cc Dish 9.1:1 CR 87mm Piston Kit

If you're rebuilding the engine in your Nissan SR20 or SR20DET for serious performance, a solid set of pistons is where you start. This Wiseco piston kit is built for demanding applications where durability and strength are critical. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength over cast aluminum, which is essential when you're pushing significant boost or high RPMs.

Wiseco has packed a lot of smart features into these pistons. You get precision ring grooves for a good seal, anti-detonation grooves to help prevent detonation damage, and features designed for extra ring seal. The crown is fully machined for accuracy, and they even have forced pin oiling to keep the wrist pins well-lubricated under stress. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and makes them more resistant to seizing. This kit is designed to handle heavy to severe duty performance builds, giving you the confidence to push your engine hard.

This kit includes four pistons, each with an 87.00 mm bore and a 32.00 mm compression height. The -12cc dish combined with the SR20DE head results in a 9.1:1 compression ratio, which is a popular target for boosted SR20 builds. Keep in mind these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
