Product Description

The Wiseco K550M865 is a high-performance, forged piston set designed specifically for the Toyota 2JZ-GTE 3.0 L twin-turbo engine. Built from 2618-grade aluminum, these pistons are engineered to endure high RPM and severe-duty tuning, making them ideal for racing or high-boost applications.

Its -14.8 cc dished crown tunes the compression ratio to around 8.4:1, which helps improve reliability and detonation resistance under aggressive or forced-induction operation. The ArmorGlide® coated skirts reduce friction and noise, while the engineered structure and forced pin oiling ensure durability under extreme conditions.

This comprehensive kit includes six pistons, 22 mm wrist pins, circlips, and premium 8650XX ring sets. Whether you're doing a full engine build or a high-power upgrade, the K550M865 delivers race-grade strength, precision, and reliability for serious 2JZ-GTE performance builds.
