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

When you're rebuilding the engine for your 1983-1989 Mitsubishi Starion, especially if it's a turbo model, you want parts that can handle the stress. This is a single Wiseco forged piston, designed to replace your stock piston and handle more demanding use. It features a -18cc dish, a 92.5mm bore, and a 35.31mm compression height, with a 0.866 inch pin diameter.

Wiseco builds these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength for durability. They've also added features like precision ring grooves, an anti-detonation groove, and a special ArmorGlide skirt coating. This coating helps reduce friction and noise, and makes the piston more resistant to seizing. The fully machined crown also helps with performance and sealing.

This piston is intended for heavy to severe duty performance applications. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's a solid option for builders looking for a well-built replacement piston for their performance Mitsubishi engine.
