CP Piston & Ring Set for Mitsubishi 4G63 w/ 2G - Bore (85mm) - Size (STD) - 8.5:1 CR

This kit includes a set of four forged pistons and the necessary piston rings to match. These are specifically made for the Mitsubishi 4G63 engine found in the 2nd generation (2G) DSM and Evo models. With a standard 85mm bore and a compression ratio of 8.5:1, these pistons are built for performance applications where you might be looking to increase boost pressure or run higher octane fuel.

CP Pistons are well-known in the performance world for their robust construction. These pistons are forged from high-strength aluminum, which is a strong material that can handle the extreme pressures and temperatures generated in a high-performance engine. The 8.5:1 compression ratio is a popular choice for turbocharged applications, as it allows for more boost without excessive detonation, while still providing decent low-end torque. The standard bore size means these are a direct replacement for stock pistons if your engine is within spec, or they can be used for a fresh rebuild on a worn engine.

When rebuilding or modifying your 4G63, using quality internal components like these forged pistons is crucial for reliability and performance. They are designed to withstand the demands of boosted engines, making them a solid option for enthusiasts looking to push their vehicle's capabilities. Remember that this set is not CARB approved and cannot be shipped to California.
