This CP forged piston and ring set SC7325V-4 fits Nissan SR20VE and SR20VET engines in 1996-2002 Primera Presea and Lucino models. The 86.5mm bore (+0.5mm oversize) and 9.0:1 compression ratio deliver reliable power for naturally aspirated or turbocharged rebuilds. Each kit includes four pistons rings wrist pins and spiro locks for complete assembly readiness.
Key Features
- Forged 2618-T6 Alloy: High-strength material handles 1000+ horsepower levels with resistance to detonation and fatigue in performance engines.
- Precision CNC Machining: Tight tolerances ensure perfect cylinder fit reducing blow-by and improving compression stability across RPM ranges.
- Premium Ring Pack: 1.2mm steel top ring 1.5mm second ring 3.0mm oil control ring for maximum sealing and minimal oil consumption.
- Accumulator Groove: Traps combustion residue to prevent ring flutter and maintain consistent power delivery under boost.
- Low-Friction Skirt Coating: Reduces piston-to-wall drag for quicker revs and less heat buildup during extended track sessions.

Frequently Asked Questions
How do I confirm this CP piston set matches my engine build?
Confirm the exact engine family, bore size, stroke, connecting rod length and small-end diameter, cylinder head and valve layout, compression height, dome or dish volume, ring pack, wrist pin, and manufacturer part number.
Can the advertised compression ratio be used for every build?
No. Final compression depends on bore, stroke, deck height, gasket thickness and bore, combustion chamber volume, piston-to-deck position, and the exact piston crown volume.
What measurements are required before final piston assembly?
A qualified engine builder should verify bore finish and clearance, ring end gap, pin fit, deck clearance, piston-to-valve clearance, rod and counterweight clearance, and all CP installation specifications.
Installation Instructions
Professional engine machining and assembly are required. Follow the current CP Pistons and engine-builder instructions for this exact part number. Measure every bore and component, verify all clearances and ring gaps, clean all parts and oil passages, use the specified lubricants and fastener procedures, confirm rotating-assembly and piston-to-valve clearance, and complete the required break-in and calibration.
