Wiseco 1400 HD Mitsubishi 4G63 Turbo -14cc Piston Shelf Stock Kit

What you get in this kit are four forged pistons, designed specifically for the Mitsubishi 4G63 turbo engine. These aren't just any pistons; they're built by Wiseco, a name known for serious performance components. They feature a -14cc dish, which is a specific design choice that affects compression ratio and how the engine breathes, especially important when you're pushing a turbo setup. This kit is intended for builders who are serious about performance and durability, aiming for heavy to severe duty applications.

Wiseco forges these pistons from 2618 aluminum right here in the USA. This material choice is key because it offers improved tensile strength, which is crucial for handling the high pressures and temperatures found in a performance turbo engine. The pistons also come with precision-machined ring grooves, anti-detonation grooves, and other features to ensure a good seal and prevent detonation. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and even makes operation quieter. The crown of each piston is fully machined, and they feature forced pin oiling to keep the wrist pins well-lubricated under stress.

This piston set is a solid option for a wide range of sport compact vehicles, including models like the Mitsubishi Eclipse, Plymouth Laser, and Eagle Talon from the early 90s. When you're rebuilding a performance engine for heavy or severe duty, using well-built components like these Wiseco pistons is essential for achieving your goals and ensuring reliability. Remember that these are not CARB approved and cannot be shipped to California.
