CP Piston & Ring Set for Nissan SR20DE/DET - Bore (88mm) - Size (+2.0mm) - CR (8.5) Set of 4

CP Pistons is well-known for making strong, reliable internal engine components. This piston and ring set is built for the Nissan SR20DE and SR20DET engines found in the 1989-1998 Nissan 240SX. If you're rebuilding the top end of your engine, especially if you're looking to increase displacement or handle more power, a set of forged pistons like these is a solid choice.

This set features pistons with an 88mm bore, which is 2.0mm larger than the stock bore size. This increase in bore diameter, combined with the specific compression ratio of 8.5:1, is designed to work with engines that have been modified or are being rebuilt to handle higher performance levels. Forged pistons are made from a solid block of material that is heated and hammered into shape, making them significantly stronger and more durable than cast pistons. This strength is crucial for engines that see increased cylinder pressures from turbocharging, higher boost levels, or aggressive tuning.

This set includes four pistons and the necessary rings to match. When installing these, remember that they are an oversize part, so proper cylinder wall preparation and honing are essential to ensure a good seal and long engine life. Always refer to the manufacturer's installation instructions for precise details on fitting and break-in procedures. Please note that this part is not CARB approved and cannot be shipped to California.
