CP Piston & Ring Set for Nissan SR20DE/VET - Bore (87.0mm) - Size (+1.0mm) - CR (9.0)

This package includes a set of four forged pistons and their corresponding rings, specifically made for Nissan SR20DE and SR20VET engines. These pistons are designed to be 1.0mm larger than stock, with a bore size of 87.0mm, and feature a 9.0:1 compression ratio. This setup is ideal for builders looking to refresh or upgrade their engine's internal components, especially when dealing with worn cylinders or aiming for a specific performance target.

CP Pistons are well-known for their robust construction, and these forged units are no exception. Forging the aluminum creates a stronger, more durable piston that can better withstand the increased pressures and temperatures found in performance or modified engines. The 9.0:1 compression ratio offers a good balance, suitable for naturally aspirated builds or those using moderate boost levels, providing improved power output without being overly sensitive to fuel quality. The included rings are matched to the pistons and bore size, ensuring a proper seal for optimal performance and engine longevity.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and break-in procedures. Because these are an oversized piston (+1.0mm), cylinder honing or boring will be required to achieve the correct fit. This set is a solid option for anyone rebuilding a Nissan SR20-series engine who needs reliable, high-performance internal components. Please note that this part is not CARB approved and cannot be shipped to California.
