Wiseco Mitsubishi 4G63 85.50 mm Bore 35.00 mm CH 1.00 CC Piston Set

If you're rebuilding the engine in your 1990-1992 Eagle Talon for serious performance, Wiseco's Professional Series forged pistons are a solid choice. These aren't your average pistons; they're built from the ground up for heavy-duty race applications where reliability under extreme stress is critical. Wiseco machines these pistons from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for the demands of high-performance engines.

Wiseco puts a lot of thought into the details that make a difference. You'll find precision ring grooves, anti-detonation grooves, and features designed to improve ring seal, all contributing to better combustion efficiency and durability. The piston crowns are fully machined, and they incorporate forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, these pistons come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when pushing an engine hard.

This set includes four pistons, each with an 85.50 mm bore, a 35.00 mm compression height, and a 0.8268-inch pin diameter. They are designed to withstand severe duty performance, making them a strong option for builders aiming for maximum output and longevity in their 4G63 engine. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
