Product Description

The Wiseco K550M87 is a professional-grade forged piston set engineered for Toyota's 2JZ-GTE engine, commonly used in the 1993-1998 Supra. Built from high-strength 2618 aluminum, these pistons are tailored for performance applications where reliability and durability matter - especially under high RPM and boost.

With a -14.80 cc dish volume, the compression ratio is lowered (~8.5:1), making this kit well-suited for turbocharged setups that prioritize detonation resistance. The ArmorGlide® skirt coating reduces friction and operational noise while promoting longevity. Meanwhile, the forced pin oiling system helps ensure consistent lubrication of the wrist pins during heavy use.

This full six-piston kit includes everything you need: wrist pins, circlips, and a top-tier 8700XX ring set. Whether you're building a high-boost street car, a dedicated race engine, or restoring a 2JZ-GTE for serious performance, the Wiseco K550M87 offers race-ready strength and precision.
