CP Piston & Ring Set for Mitsubishi Evo 8/9 - Bore (85.0mm) - Size (Std) - CR (9.5) - Set of 4

This set includes four forged pistons and the necessary rings to rebuild the engine in your 1993-1999 Mitsubishi Eclipse, Eagle Talon (1993-1998), Plymouth Laser (1993-1994), or 2003-2006 Mitsubishi Lancer Evolution. These pistons are specifically designed for the high-performance demands of turbocharged 4-cylinder engines, offering a standard bore size of 85.0mm and a compression ratio of 9.5:1. This setup is a popular choice for those looking to enhance their engine's power and durability, especially when rebuilding or upgrading a performance-oriented vehicle like the Evo.

CP Pistons are well-known for their robust construction, utilizing high-strength forged aluminum to withstand the increased cylinder pressures and temperatures common in modified turbocharged applications. The standard bore size ensures a precise fit for engines within the specified range, and the 9.5:1 compression ratio strikes a good balance for street performance and track use, allowing for good power output without excessive detonation risk on premium fuel. This set is engineered to be a direct replacement for your stock pistons, simplifying the rebuild process for mechanics familiar with these platforms.

When undertaking an engine rebuild with these pistons, it's important to ensure all supporting components are in good condition. This includes checking the connecting rods for straightness and wear, ensuring proper cylinder wall preparation, and using high-quality engine bearings and gaskets. Proper balancing of the rotating assembly is also crucial for engine longevity and smooth operation at higher RPMs. This piston set is a solid foundation for a performance engine build, providing the strength and reliability needed for demanding applications.
