Wiseco Mits Turbo DISH -17cc 1.378 X 86MM Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance applications. The -17cc dish volume is a key design choice for managing compression ratios in turbocharged Mitsubishi 4G63 engines, especially when aiming for significant boost levels. Each piston is precisely machined in the USA, featuring advanced details like anti-detonation grooves and enhanced ring seal features to ensure reliability under heavy loads.

The ArmorGlide skirt coating on these pistons is notable for reducing friction and wear, contributing to quieter operation and improved seizure resistance. This coating, combined with forced pin oiling, helps keep these components running smoothly even in severe duty race builds. The fully machined crown ensures consistent combustion chamber volume, which is critical for predictable engine performance.

This kit includes four pistons, each with an 86.00 mm bore and a 0.866-inch pin diameter, designed to fit the Mitsubishi 4G63 engine. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their sport compact builds, this Wiseco piston set offers a well-built foundation.
