CP Piston & Ring Set for Honda F20C/F22C - Bore (87.5mm) - Size (+0.5mm) - Compression Ratio (9.0)

This kit includes four forged pistons and a complete set of performance piston rings, ready for your Honda F20C or F22C engine rebuild. These are designed specifically for the 2000-2009 Honda S2000, giving you a direct fit for a serious engine project. If you're looking to rebuild your S2000's high-revving engine, whether for boosted applications or a naturally aspirated refresh, these pistons are a solid choice.

CP Pistons are well-known in the performance world for their strong construction. These pistons are forged from high-strength aluminum, which makes them durable enough to handle increased cylinder pressures. The 87.5mm bore size is a +0.5mm oversize, meaning these are intended for engines that have been bored out to accommodate them during a rebuild. This specific set is designed to achieve a 9.0:1 compression ratio, which is a good balance for many performance builds, offering flexibility whether you plan to add a turbocharger or supercharger, or keep it naturally aspirated.

When rebuilding an engine, proper preparation is key. Ensure your cylinders are honed to the correct size for these +0.5mm pistons and that you follow the manufacturer's recommended ring gap specifications. These pistons are a critical component for anyone looking to restore or enhance their S2000's engine performance. Please note that this part is not CARB approved and cannot be shipped to California.
