Wiseco 1400 HD Mitsu EVO 8 - 4G63 Turbo -14cc Piston Shelf Stock Kit

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Lancer, Eagle Talon, or Plymouth Laser, especially for a performance build, a strong set of pistons is crucial. These Wiseco Professional Series pistons are forged from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for demanding applications where stock components might not hold up. They are designed and machined in the USA, ensuring a high level of precision throughout the manufacturing process.

Wiseco has incorporated several features into these pistons to enhance their performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is vital for maintaining compression and preventing blow-by under high stress. The fully machined crown ensures consistent combustion chamber volume, and the forced pin oiling helps keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction and noise, while also providing resistance to seizure, contributing to a quieter and more reliable operation even in severe duty race builds.

This kit includes four pistons, each with an 85.00 mm bore and a -14cc dish volume, designed to work with the 4G63 engine. Remember that these pistons are not CARB approved and cannot be shipped to California. For a successful installation, always refer to the manufacturer's detailed instructions, as specific assembly techniques and clearances are critical for optimal performance and longevity.
