Wiseco Mitsubishi 4G64 w/4G63 Heads 10.5:1 E85 - Single Piston

Wiseco is well-known for making strong internal engine components, especially for performance builds. This single forged piston is designed for Mitsubishi 4G64 engines when using 4G63 heads, with a bore size of 85.25 mm. It's set up for a 10.5:1 compression ratio and is suitable for E85 fuel, making it a solid choice for serious engine builders.

This piston is forged and machined in the USA from 2618 aluminum, which gives it improved tensile strength for demanding applications. It features precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure. The crown is fully machined, and the piston includes forced pin oiling to keep things well-lubricated under heavy load.

This piston is built to handle heavy to severe duty performance applications. Please note that this part is not CARB approved and cannot be shipped to California.
