The JE Pistons Ultra Series Piston Kit for the Toyota 2JZ-GTE features a forged 2618 aluminum construction with an 86mm (3.386 in.) bore and a 9.0:1 compression ratio. Designed for high-horsepower racing applications, these pistons incorporate advanced technologies to enhance strength, durability, and performance. Key features include JE's proprietary Aligned Grain Flow forging process, which maximizes tensile strength for extreme cylinder pressures. A skirt coating reduces friction and wear while minimizing operating noise, particularly during cold starts. The thermal barrier crown coating helps reflect heat into the combustion chamber, lowering piston crown temperatures and improving exhaust gas flow. Lateral gas ports maintain a strong ring seal under high RPM and boost conditions, and optimized pin oiling ensures proper lubrication for reduced wear and friction. This set includes six pistons with high-strength, thick-wall wrist pins designed for demanding high-performance applications. These pistons are ideal for high-boost builds and power-adder setups.
