Overview
The CP Piston 2JZ-GTE 86/STD Stroke 8.5:1 is engineered for high-performance turbocharged applications, offering the strength and reliability needed for engines running elevated boost levels. Featuring a standard 86mm bore and stroke, these pistons maintain factory fitment while the lowered 8.5:1 compression ratio enhances detonation resistance, making them ideal for aggressive forced induction setups. Manufactured from premium forged 2618 aluminum alloy, they deliver excellent thermal stability and strength. Key design elements include deep valve reliefs for compatibility with high-lift cams, accumulator grooves to reduce ring flutter and improve combustion sealing, and dual forced pin oilers to ensure consistent wrist pin lubrication. The pistons are fully CNC machined and balanced to within +/- 1 gram for precise engine operation. Each set includes high-performance rings and standard 5310 wrist pins, with optional upgrades available. This combination of durability, precision, and boost-friendly compression makes them a top choice for serious 2JZ-GTE builds.
