CP Piston & Ring Set Mitsubishi 4G64 w/ 2G Head - Bore (87.5mm) - Compression Ratio 10.0

If you're rebuilding the engine in your Mitsubishi 4G64 and aiming for improved performance, a solid set of forged pistons is a critical component. This set from CP Pistons is specifically designed for the 4G64 engine when fitted with a 2G cylinder head, featuring an 87.5mm bore and a 10.0:1 compression ratio. This compression level is a popular choice for naturally aspirated builds or those running moderate boost, offering a good balance between power and reliability.

CP Pistons are well-known for their robust construction, and this set is no exception. Forged from high-strength aluminum alloy, these pistons are significantly stronger and more durable than cast pistons, making them ideal for engines that will see higher RPMs or increased cylinder pressures. The 87.5mm bore size is a common upgrade for the 4G64, allowing for a slight increase in displacement. The included rings are designed to work seamlessly with the pistons, ensuring proper sealing for optimal compression and oil control. This set is engineered to fit right into your 4G64 build, assuming the 2G head configuration is in place.

When undertaking an engine rebuild of this caliber, it's important to ensure all supporting components are up to the task. This piston set is a significant upgrade for performance-oriented builds. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
