Wiseco Toyota 3SGTE 4v Dished -6cc Turbo 86.5mm +.5mm Oversize Piston Kit

If you're building a high-performance Toyota 3SGTE engine, this Wiseco piston kit is designed for serious racers and builders. These are forged pistons, meaning they start as a block of 2618 aluminum that's heated and hammered into shape. This process gives them improved tensile strength compared to cast pistons, making them well-suited for heavy to severe duty race applications where durability is key.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves and anti-detonation features that help improve ring seal and prevent damage under high boost. They also come with an ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction, makes operation quieter, and resists seizure, which is crucial when you're pushing your engine hard. The crown is also fully machined, and they feature forced pin oiling to keep the wrist pins well-lubricated.

This kit includes four pistons, each measuring 86.50 mm bore size, which is a 0.5 mm oversize from the standard bore. The compression height is 35.00 mm, and they use a 0.866-inch diameter pin. Keep in mind these are not CARB approved and cannot be shipped to California. They are intended for sport compact applications and are a solid option for those rebuilding their top end for extreme performance.
