CP Piston & Ring Set for Mitsubishi 4G63 2G/Evo 8/9 - Bore 86.0mm - Size +1.0mm - Stroke 88 - CR 9.5

This is a CP Pistons forged piston and ring set specifically for the Mitsubishi 4G63 engine, commonly found in the 2G DSM and Evolution 8/9 models. This set is designed for an 86.0mm bore and is sized at +1.0mm, meaning it's intended for engines that have been bored out to accommodate this larger size. With a stroke of 88mm and a compression ratio of 9.5:1, these pistons are built for performance applications where increased displacement and power are desired.

CP Pistons are well-known for their robust construction and are a popular choice for builds pushing the limits of the 4G63 engine. These pistons are forged from high-strength aluminum alloy, which offers a strong yet lightweight solution for high-performance engines. The forging process creates a denser, more durable grain structure compared to cast pistons, making them resistant to the extreme pressures and temperatures generated during high-output operation. This set includes the necessary rings, ensuring you have the critical components for proper sealing and oil control. The 9.5:1 compression ratio is a versatile choice, offering a good balance between power output and pump gas drivability for many modified 4G63 setups.

When rebuilding or modifying your 4G63 engine, choosing reliable internal components is crucial. This CP Pistons set is a solid option for those looking to enhance their engine's performance and durability. Remember that this part is not CARB approved and cannot be shipped to California. Always consult with your engine builder or a qualified mechanic to ensure this piston set is the right choice for your specific build goals and to confirm all necessary supporting modifications.
