Wiseco Nissan Turbo Domed +14cc 1.181x87.5 Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of high-performance Nissan RB26DETT engines. The material choice here is key; 2618 aluminum offers improved tensile strength over other alloys, making it a solid choice for boosted applications where cylinder pressures can get quite high. This particular set is designed with a domed crown, featuring a +14cc volume, and a compression height of 1.181 inches, which is crucial for achieving your target compression ratio when rebuilding your engine.

Wiseco doesn't stop at just the forging. These pistons are fully machined, including precision ring grooves that are designed for optimal sealing. You'll also find an anti-detonation groove, which helps prevent detonation damage under extreme conditions. The crown itself has additional features to improve ring seal, ensuring every bit of power from your combustion is put to the crankshaft. For added durability and reduced friction, the skirts are treated with an ArmorGlide coating, which helps prevent seizure and contributes to quieter operation. Plus, the forced pin oiling design ensures the wrist pin receives adequate lubrication, a critical detail for longevity in a performance engine.

This kit includes a set of six pistons, along with premium rings, ready for installation in your RB26DETT engine. Keep in mind these are intended for serious racing and heavy-duty builds, so they are not CARB approved and cannot be shipped to California. If you're building a performance Nissan and need a robust piston set, these Wiseco Professional Series pistons are a well-built option.
