Product Description

The Wiseco K677M86AP piston set is a high-performance, forged solution for Toyota's 2JZ-GTE 3.0 L engine, commonly used in Supra and Soarer models from 1993 to 1998. Crafted from aerospace-grade aluminum with an asymmetric skirt design, these pistons provide exceptional durability, stability, and friction reduction for high-power and high-RPM applications.

With a compression height of 34 mm and a 9.51:1 compression ratio, the pistons are optimized for forced induction and race engines while maintaining reliability. The ArmorGlide coating enhances ring seal and reduces wear, and strutted forging reinforces high-stress areas.

The kit includes all necessary components for installation: six pistons, wrist pins, circlips, and a performance ring set. The offset pin design reduces piston rock and noise, providing a reliable and high-performance upgrade for the 2JZ-GTE platform.
