Product Description

The Wiseco **K677M8625AP** is a professional-series forged piston kit specifically made for Toyota's 2JZ-GTE 3.0 L engine (found in the 1993-1998 Supra and Soarer). Built from 2618-grade aluminum and optimized with strutted forging, these pistons are engineered for severe-duty motorsports use.

With an 86.25 mm bore and a -5.3 cc dished crown, this set hits a compression ratio of approximately 9.5:1 - a sweet spot for high-performance builds balancing power and reliability. The ArmorGlide® coating reduces friction and enhances longevity, while forced-pin oiling ensures consistent lubrication under high RPM stress.

This complete kit includes six forged pistons, wrist pins, circlips, and a high-quality 8625XX ring set - everything needed for a top-tier rotating assembly upgrade on a 2JZ-GTE. It's ideal for tuners and engine builders aiming for a durable, high-output engine build.
