Overview 

The UEM Piston 2JZ-GTE 86.75/STD Stroke -7.5 is a high-performance piston designed specifically for the Toyota 2JZ-GTE engine, offering increased durability and precision for demanding applications. With an oversized 86.75mm bore, it is ideal for engines that have been slightly overbored to restore cylinder wall integrity or gain a slight increase in displacement. It retains compatibility with the standard stroke, preserving factory crankshaft dimensions and ensuring balanced engine dynamics. The -7.5mm compression height allows for fine-tuning of the compression ratio, making it well-suited for turbocharged and high-horsepower builds. Constructed from high-strength materials, this piston is engineered to withstand extreme temperatures and pressures, making it perfect for forced induction setups. Whether used in motorsport or high-performance street applications, the UEM 86.75 piston delivers reliability, strength, and performance tailored to the needs of serious 2JZ-GTE engine builds.
