Wiseco Mitsubishi Turbo -18cc 1.390 X 92MM Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components for performance applications. If you're building a serious engine for your 1983-1989 Mitsubishi Starion, this Professional Series piston set is designed to handle the demands of heavy to severe duty racing. These aren't your average pistons; they're built with a focus on durability and performance for builders who push their engines hard.

Each piston is forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for high-stress situations. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and keep combustion contained. The piston crown is fully machined, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making for a smoother-running and more reliable engine.

This set includes four pistons, each with a -18cc dish and a 92mm bore, designed specifically for the Mitsubishi 4G54B engine. They are intended for sport compact applications and are built to withstand the rigors of racing. Please note that these pistons are not CARB approved and cannot be shipped to California.
