Wiseco Mits Turbo DISH -17cc 1.378 X 85.5 Piston Shelf Stock

When you're rebuilding a performance Mitsubishi 4G63 engine, especially for turbo applications, you need pistons that can handle the stress. This Wiseco piston is designed for that kind of build, offering a dish volume of -17cc and a bore size of 85.50 mm. It's constructed from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the higher pressures and temperatures found in boosted engines.

Wiseco puts a lot of thought into the details here. You get precision ring grooves, an anti-detonation groove, and features that help improve ring seal, all working together to keep combustion contained and efficient. The piston crown is fully machined, and the piston itself features forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and better durability under demanding conditions.

This piston is sold individually, so you'll need to order the correct quantity for your engine. It's built for heavy to severe duty performance applications, meaning it's intended for serious engine builds where reliability under stress is paramount. Keep in mind this part is not CARB approved and cannot be shipped to California.
