Wiseco 97-02 Mitsubishi Lancer 4G93/4G94 1.8L 81.5mm Bore .020 Size -2.5cc FT 1.190CH 8.9 Piston Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston kit is built for Mitsubishi Lancer models with the 4G93 or 4G94 1.8L engine from 1997-2002. These aren't your average pistons; they are designed for serious racers and builders who push their engines hard, handling heavy to severe duty performance builds.

Forged and machined right here in the USA from 2618 aluminum, these pistons offer improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, all contributing to better performance and durability. The crown of each piston is fully machined, and they come with forced pin oiling to keep things lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making them a solid choice for high-performance engines.

This kit includes a set of four pistons, each with an 81.5mm bore and a .020 inch undersize. The compression height is 30.25mm, and they use a 0.748 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds where engine strength and reliability are paramount.
