Wiseco Mitsubishi 4G63 E85 1400HD 86mm Single Piston

If you're building a high-performance Mitsubishi 4G63 engine, especially one designed to run on E85 fuel, this Wiseco forged piston is a solid choice. Wiseco crafts these pistons from 2618 aluminum, which offers improved tensile strength over other aluminum alloys, making them well-suited for the demands of racing and severe duty applications. The 86mm bore size is a common specification for many 4G63 builds, and this piston is designed to handle the stresses that come with serious performance tuning.

Wiseco includes several features to enhance performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for maintaining compression and preventing blow-by under high cylinder pressures. The piston crown is fully machined for a clean combustion chamber surface, and the forced pin oiling helps keep the wrist pin lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, contributing to a quieter and more durable engine operation.

This piston is intended for heavy to severe duty race builds, meaning it's built to withstand significant abuse. Keep in mind that this part is not CARB approved and cannot be shipped to California. For a complete engine build, you'll need to purchase the appropriate number of these pistons for your 4G63 engine.
