CP Piston & Ring Set for Nissan SR20DE/DET - Bore (86mm) - Size (STD) - CR (9.0)

If you're rebuilding the engine in your 1989-1998 Nissan 240SX, especially if you're looking to get more performance out of your SR20DE or SR20DET, this forged piston and ring set from CP Pistons is a solid choice. These pistons are built to handle the increased stress and heat that comes with a performance build, offering a significant upgrade over stock cast pistons. The set includes everything you need to replace your pistons and rings, ensuring a fresh start for your engine's core components.

CP Pistons are well-known for their robust construction, and this set is no different. They are forged from high-strength aluminum alloy, which makes them lighter and stronger than cast pistons. This strength is crucial for maintaining engine integrity under higher boost pressures or more aggressive tuning. The 86mm standard bore size means they're designed to fit engines with a stock bore, and the 9.0:1 compression ratio is a popular choice for many SR20 builds, offering a good balance between power and drivability, especially when paired with forced induction. The set comes complete with the necessary rings, ready for installation by a qualified mechanic.

When undertaking an engine rebuild of this caliber, precision is key. These pistons are manufactured to tight tolerances to ensure a proper fit and optimal performance within the SR20DE/DET block. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with your engine builder to ensure all specifications are met for your specific application.
