CP Piston & Ring Set for Toyota 7MGTE - Bore (83.5mm) - Size (+0.5mm) - Compression Ratio (8.4)

If you're rebuilding the engine in your 1987-1992 Toyota Supra, especially if you're pushing the limits of the 7MGTE motor, a solid set of pistons is crucial. This forged piston and ring set from CP Pistons is built to handle the demands of a performance engine build. They come in a specific 83.5mm bore size, which is a 0.5mm oversize from stock, perfect for engines that have been bored out during a rebuild to refresh cylinder walls or increase displacement slightly. The compression ratio is set at 8.4:1, a common target for modified 7MGTE engines that often see increased boost pressure.

CP Pistons are well-known in the performance world for their robust construction. These aren't cast pistons; they're forged from high-strength aluminum alloy. This forging process creates a much stronger and more durable piston that can withstand higher cylinder pressures and temperatures compared to cast alternatives. This strength is essential for engines that are tuned for more power, whether through turbo upgrades, camshaft changes, or ECU tuning. The included rings are designed to seal effectively against the cylinder walls, ensuring good compression and efficient oil control, which are vital for engine longevity and performance.

This set includes all six pistons and their corresponding rings, ready for installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and break-in procedures to get the most out of this performance component.
