Wiseco Mitsu 4G64 w/4G63 Heads 10.5:1 E85 Piston Kit

This kit includes four forged pistons, designed for Mitsubishi 4G64 engines when fitted with 4G63 cylinder heads. These pistons have an 85.00 mm bore and a 10.5:1 compression ratio, making them suitable for E85 fuel applications. They are built from 2618 aluminum, which offers improved tensile strength for demanding engine builds.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure reliable performance. The crown is fully machined, and the pistons feature forced pin oiling for better lubrication. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. These pistons are intended for heavy to severe duty race applications where durability and consistent performance are critical.

This set is designed for builders who are serious about performance and durability. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
