CP Piston & Ring Set for Honda D16Y7 - Bore (75.5mm) - Size (+0.5mm) - CR (9.0) - Set of 4

If you're rebuilding the engine in your 1996-2000 Honda Civic or 1996-1997 Civic del Sol, this forged piston and ring set from CP Pistons is built for serious performance. This set is specifically designed for the D16Y7 engine, featuring a 75.5mm bore size, which is 0.5mm oversize from stock. The compression ratio comes in at 9.0:1, making it a solid choice for builds aiming for improved power without going extreme on compression, which can be beneficial for forced induction applications or when using pump gas.

CP Pistons are well-known in the performance engine building world for their strong construction and attention to detail. These pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast aluminum, which is what most factory pistons are made from. This strength is crucial for handling the increased cylinder pressures and temperatures that come with performance modifications or high-mileage engines needing a refresh. The set includes the necessary rings, ensuring you have matched components for a proper seal.

When installing these pistons, remember they are 0.5mm oversize, so your engine block will need to be bored and honed to this specific dimension by a machine shop. This ensures a precise fit and proper piston-to-wall clearance, which is critical for engine longevity and performance. This set is intended for off-road use and is not CARB approved, meaning it cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed specifications and procedures.
