CP Piston & Ring Set for Toyota 1JZGTE - Bore (86.0mm) - Size (STD) - CR (0.9) - Set of 6

CP Pistons is well-known for building strong, reliable internal engine components for high-performance applications. This piston and ring set is specifically made for the Toyota 1JZGTE engine, a popular choice for tuners and enthusiasts looking to build serious power. If you're rebuilding the top end of your 1JZGTE, especially if you're planning on significant modifications or forced induction, a set of forged pistons like these is a critical upgrade over stock cast pistons.

These pistons are forged from high-strength aluminum, a process that creates a denser, more durable material than cast aluminum. This makes them much more resistant to the extreme pressures and temperatures generated in a performance engine, particularly when running boost or higher compression. The 86.0mm standard bore size means they're designed to fit precisely into a freshly machined 1JZGTE block, and the 0.9 compression ratio is a common target for builds aiming for a balance of power and pump gas compatibility, though tuning will be essential to realize its full potential. This set includes six pistons and their corresponding rings, ready for installation.

When installing these pistons, ensure your engine block is properly machined to the correct bore size and honed to a finish suitable for forged pistons. Proper balancing of the rotating assembly is also crucial for engine longevity at higher RPMs. This set is designed to be a direct replacement for the factory pistons, but it's always recommended to consult your engine builder or a trusted mechanic for specific installation procedures and torque specifications.
