CP Piston & Ring Set for Honda F20C - Bore (87.5mm) - Size (+0.5mm) - Compression Ratio (12.5)

This product includes a set of four forged pistons and the necessary piston rings for your 2000-2003 Honda S2000 with the F20C engine. These are a +0.5mm oversize set, meaning the bore diameter is 87.5mm, which is useful if your engine block has been previously bored or requires a slight increase in bore size for optimal performance and sealing. The pistons are designed to achieve a 12.5:1 compression ratio, a notable increase over stock, which can significantly boost power output when paired with appropriate tuning and supporting modifications.

CP Pistons is well-known for their forged pistons, which are considerably stronger and more durable than cast pistons. This strength is crucial for high-performance applications or engines that see demanding use, as forged pistons can better withstand the higher cylinder pressures and temperatures associated with increased power. The included rings are essential for proper cylinder sealing, oil control, and heat transfer from the piston to the cylinder wall. This set is a solid option for rebuilding or upgrading the F20C engine, especially if you're aiming for improved performance and reliability under stress.

When installing these pistons, it's important to ensure your engine block is properly prepared, including checking the cylinder bore for straightness and finish. Due to the increased compression ratio, careful attention to engine tuning, fuel octane, and cooling system efficiency will be necessary to safely harness the added power and prevent detonation. Please note that this piston set is not CARB approved and cannot be shipped to California.
