Product Description

The Wiseco K615M87AP is a professional-series forged piston kit tailored for the Toyota 3S-GTE 2.0L 16V turbo engine, commonly found in Celica and MR2 models. With a bore of approximately 87 mm and a -6 cc dish, these pistons are optimized for turbocharged performance while maintaining robust strength via 2618 aluminum forging.

The ArmorGlide® coating on the skirts lowers friction and helps prevent scuffing, even under intense conditions. Strutted forging adds rigidity to handle high boost loads, while the forced-pin oiling system ensures the wrist pins remain well-lubricated, critical in high-RPM or high-stress applications. The set comes with a pre-gapped 8700XX ring pack, simplifying installation and ensuring strong sealing.

These pistons are ideal for performance builds, whether you're rebuilding a high-boost 3S-GTE for racing or tuning it for street use. They offer a durable, race-ready foundation for your engine project.
