CP Piston & Ring Set for Mitsubishi 4G63 2G/Evo 8/9 -Bore (86.0mm)-Size (+1.0mm)-Stroke (100)-Set 4

These CP Pistons are forged from high-strength aluminum alloy, a material chosen for its excellent strength-to-weight ratio, which is crucial for high-performance engine builds. Specifically, this set is designed for the Mitsubishi 4G63 engine found in the 2G DSM and Evolution 8/9 models. The pistons measure 86.0mm in bore diameter and are 1.0mm oversize, intended for engines that have been bored out to accommodate this size during a rebuild. The 100mm stroke specification is also noted for this particular application.

Building a 4G63 engine, especially for performance applications, demands components that can handle increased cylinder pressures and temperatures. CP Pistons are well-known in the performance community for their robust construction and precision manufacturing. This set includes the pistons and rings, providing a solid foundation for your engine's top end. The forged construction means these pistons are significantly stronger than cast aluminum pistons, making them a popular choice for turbocharged or supercharged applications where reliability under stress is paramount. This set is for a 4-cylinder configuration.

When undertaking an engine rebuild of this caliber, it's important to ensure all components are properly matched and installed according to manufacturer specifications. This set is designed to fit the specified Mitsubishi engines, but always consult your engine builder or service manual for precise installation procedures, including ring gap settings and lubrication requirements.
