Product Description

The Wiseco K550M86 is a high-performance forged piston kit designed for Toyota's 2JZ-GTE 3.0 L twin-turbo engine, commonly used in 1993-1998 Supra models and compatible with select Lexus SC300 / Soarer applications. Built from 2618 aerospace-grade aluminum, these pistons provide outstanding strength and durability under high-RPM and high-load conditions.

Featuring a -14.80 cc flat-top crown, the compression ratio is optimized (~8.5:1) for turbocharged setups, ensuring improved detonation resistance. ArmorGlide® skirt coating reduces friction and noise, while strutted forging and precision ring grooves enhance reliability during extreme performance builds. Forced pin oiling ensures the wrist pins receive proper lubrication under high stress.

This complete kit includes six pistons, wrist pins, circlips, and a premium piston ring set, making it perfect for full engine rebuilds, racing applications, or street performance upgrades. The K550M86 delivers professional-grade performance and durability for serious 2JZ-GTE engine builds.
