Product Description

The Wiseco K550M87AP is a performance-grade forged piston kit designed for Toyota's 2JZ-GTE 3.0 L twin-turbo engine. Built from 2618 aerospace-grade aluminum, these pistons are engineered to endure high stress, high RPM, and boost-heavy applications.

With a -14.8 cc dished crown, the compression ratio is tuned to ~8.5:1, making this kit ideal for turbocharged setups that demand detonation resistance and reliability. The ArmorGlide® coating on the skirts minimizes friction and wear, while the strutted forging structure ensures the pistons remain strong under load. Forced pin oiling provides dependable wrist-pin lubrication for long-term durability.

This full 6-cylinder kit includes all the hardware you need: pistons, 22 mm wrist pins, circlips, and a premium 8700XX ring set. Whether you're building a high-power race engine or a reliable tuned Supra or 2JZ-GTE platform, the K550M87AP delivers strength, precision, and performance for serious builds.
