Product Description

The Wiseco K677M865AP is a professional-series, forged piston kit specifically designed for the Toyota 2JZ-GTE 3.0 L engine - the powerhouse found in the Supra MK IV and select Lexus models. These pistons are crafted from high-grade 2618 aluminum to withstand high-performance, high-boost applications.

With a dished crown of -5.3 cc, this kit delivers a 9.6:1 compression ratio - a balanced figure that suits both high-boost setups and aggressive tuning. The strutted-forge design strengthens the piston structure, while the ArmorPlating® coating enhances durability by resisting abrasion and wear. Forced pin-oiling ensures your wrist pins stay lubricated even under demanding conditions.

This comprehensive kit comes with a full ring set, forged pistons, and durable wrist pins, making it an excellent choice for performance builds or race engines. When installing, make sure to verify ring gaps, clearances, and torque settings to get the most out of your build.
