CP Piston & Ring Set for Toyota 7MGTE - Bore (83mm) - Size (Standard) - Compression Ratio (8.4)

This kit includes a set of four forged pistons and matching piston rings, specifically made for the 1987-1992 Toyota Supra with the 7MGTE engine. These are standard bore pistons, meaning they are designed to fit within the original cylinder wall dimensions, making them a direct replacement for worn-out factory pistons. The 8.4:1 compression ratio is a notable change from stock, often chosen for builds that plan to use forced induction, like turbochargers, as it helps manage cylinder pressures and heat under boost.

CP Pistons is known for making well-built internal engine components, and these forged pistons are no exception. Unlike cast pistons, forged pistons are made from a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston that can withstand higher temperatures and pressures, which is crucial for performance applications. The included rings are designed to seal against the cylinder walls, ensuring good compression and preventing oil from entering the combustion chamber. This set is a solid option if you're rebuilding the top end of your 7MGTE and want a component that can handle more than stock power levels.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Because these are designed for performance, they often require specific attention during assembly to ensure longevity and proper function. Remember that this kit is not CARB approved and cannot be shipped to California.
