Carrillo SC7327PVD-1 CP Forged Piston Nissan SR20DE 86.5mm Bore 8.5:1 Single

The Carrillo SC7327PVD-1 is a single forged performance piston from CP-Carrillo's Sport Compact lineup, engineered for the Nissan SR20DE engine in forced-induction and high-performance applications. Sold individually, this piston allows builders to replace or upgrade one cylinder at a time without purchasing a full set.

CP-Carrillo pistons are computer-modeled and precision-forged from 2618-T61 aluminum alloy — the preferred material for high-boost and power-adder applications due to its superior strength and thermal resilience compared to cast alternatives.
