Wiseco Mits Turbo DISH -17cc 1.378 X 87MM Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Mitsubishi 4G63 engines. The -17cc dish volume is a key design choice for managing compression ratios in boosted applications, helping you achieve your build's power goals without excessive cylinder pressure. Each piston is precision machined right here in the USA, ensuring tight tolerances for optimal performance and durability.

You'll find features like precision ring grooves, anti-detonation grooves, and enhanced ring seal designs to keep combustion contained and efficient, even under severe duty. The ArmorGlide skirt coating is a notable addition; it's designed to resist seizure, reduce friction, and quiet down operation, which is especially important in high-performance builds where every bit of efficiency counts. These pistons are fully machined on the crown and feature forced pin oiling, demonstrating a commitment to longevity and reliability in demanding race applications.

This set includes four pistons, each with an 87.00 mm bore and a 35.00 mm compression height, using a 0.866-inch pin diameter. While these are built for heavy to severe duty, please note they are not CARB approved and cannot be shipped to California. If you're building a high-output Mitsubishi 4G63, these pistons are a solid option to consider for the core of your engine.
