CP Piston & Ring Set for Mitsubishi 4G63 2G - Bore (86mm) - Rod (156mm) - Dish (-14.1cc) - CR (8.5)

This kit includes a set of four forged pistons and matching piston rings specifically made for the Mitsubishi 4G63 2nd Generation engine. These pistons are designed to fit an 86mm bore and feature a -14.1cc dish volume, resulting in a compression ratio of 8.5:1. This setup is ideal for builders looking to assemble or rebuild a robust 4-cylinder engine, often found in performance applications where durability and improved power output are key goals.

CP Pistons are well-known for their strong construction, and these pistons are no exception. They are forged from high-strength aluminum alloy, a process that creates a denser, more durable piston capable of withstanding higher cylinder pressures and temperatures compared to cast pistons. The specific dish volume and pin height are engineered to work with a 156mm connecting rod, ensuring proper piston-to-valve clearance and optimal combustion chamber shape for the target compression ratio. This attention to detail in design and manufacturing helps ensure reliable performance and longevity for your engine build.

When undertaking an engine rebuild with these pistons, it's important to ensure all supporting components are up to the task. This includes proper balancing of rotating assemblies, appropriate cylinder head modifications, and a reliable engine management system to take full advantage of the improved hardware. Remember that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for precise fitting and assembly details.
