CP Piston & Ring Set for Nissan SR20DE w/ Turbo - Bore (87mm) - Size (+1.0mm) - Compression Ratio (9

Forged from high-strength 2618 aluminum alloy, these CP Pistons are built to handle the demands of a turbocharged SR20DE engine in your 1989-1998 Nissan 240SX. The 87mm bore size, combined with a +1.0mm over piston, is designed to work with a freshly bored and honed engine block, ensuring a precise fit and optimal sealing for improved performance and durability under boost.

These pistons feature a 9.0:1 compression ratio, which is a well-balanced choice for turbocharged applications, allowing for significant power gains without excessive detonation risk when properly tuned. The included ring set is specifically matched to the piston design, ensuring proper tension and sealing for efficient combustion and oil control. CP Pistons are known for their robust construction, utilizing advanced forging techniques to create a piston that is both lightweight and incredibly strong, able to withstand higher cylinder pressures and temperatures common in boosted engines.

When rebuilding or upgrading your SR20DE, using a set of quality forged pistons like these from CP Pistons is a critical step for reliability and performance. They are designed to be a direct replacement for the stock pistons, assuming your engine block has been machined to the specified bore size. Remember that this kit is not CARB approved and cannot be shipped to California.
