CP Piston & Ring Set for Nissan SR20DE w/ Turbo - Bore (89.5mm) - Size (+3.5mm) - CR (9.0)

CP Pistons is well-known for making strong, reliable internal engine components, and this forged piston and ring set for the Nissan SR20DE engine with a turbocharger is a prime example of their work. If you're building a performance SR20DE for boosted applications, these pistons are designed to handle the extra stress and heat that comes with forced induction.

These pistons are forged from high-strength aluminum, a process that creates a denser, more durable material compared to cast pistons. This makes them much more resistant to detonation and the higher cylinder pressures common in turbocharged engines. This specific set features a bore size of 89.5mm, which is 3.5mm over the stock bore, and a compression ratio of 9.0:1. This compression ratio is ideal for turbocharged setups, providing a good balance between power and the ability to run safe boost levels without excessive detonation risk. The set includes the pistons and the necessary rings to get your engine rebuilt.

When rebuilding an SR20DE with a turbo, using forged pistons like these is a critical step for ensuring long-term reliability and performance. They are built to withstand the demands of higher horsepower and boost pressures. Please note that this part is not CARB approved and cannot be shipped to California.
