Wiseco Mitsubishi Turbo -18cc 1.390 X 92.5 Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your Mitsubishi 4G54B engine. The -18cc dish volume is specifically designed to work with turbo applications, helping to achieve a desired compression ratio for boosted builds. Each piston is precision machined in the USA, ensuring a well-built component ready for demanding use.

Wiseco's Professional Series pistons are packed with features for durability and performance. You'll find precision ring grooves, anti-detonation grooves, and additional features for improved ring seal. The crown is fully machined, and they incorporate forced pin oiling to keep the wrist pins lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in high-performance engines.

This shelf stock kit includes everything you need for a set of four pistons, ready to be installed in your 1983-1989 Mitsubishi Starion, 1987-1989 Chrysler Conquest, or 1984-1986 Plymouth Conquest. They are designed to withstand heavy to severe duty performance applications, making them a solid option for racers and serious builders looking to push their engine's limits.
