JE Pistons Toyota 1JZ-GTE 86mm Bore -3.2cc Dish 9.0:1 CR - Set of 6

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications, offering the tensile strength needed for serious engine builds. Specifically designed for the Toyota 1JZ-GTE engine, this set of six pistons features an 86mm bore and a -3.2cc dish, resulting in a 9.0:1 compression ratio. This compression level is a popular choice for those looking to balance pump gas drivability with the potential for significant power gains, especially when paired with forced induction.

JE Pistons brings over 75 years of experience to their manufacturing process, with these pistons being forged and machined 100% in the USA. They incorporate a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and utilizing a shorter wrist pin for further weight savings. Depending on the specific application, an accumulator groove may be included to help reduce combustion gas pressure, improving ring flutter and ensuring a consistent ring seal for reliable power delivery. Additionally, a skirt coating, if applicable for this engine, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and extended engine life.

This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, making it a comprehensive solution for your engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
