CP Pistons SC7303 Nissan RB30 Forged Piston Kit
CP Pistons SC7303 Nissan RB30 Forged Piston Kit
The CP Pistons SC7303 Forged Piston Kit is engineered for Nissan RB30 performance engine builds, including RB30/RB25DET and RB30/RB26DETT twin-cam conversions. Manufactured in the USA from premium 2618 forged aluminium, these pistons are CNC machined for exceptional strength, durability and reliability in high-boost street, drag and circuit racing applications. Designed to withstand extreme cylinder pressures, the SC7303 is ideal for serious performance builds where strength and tuning flexibility are essential.
Featuring an 87.00 mm (+1.00 mm oversize) bore, 86 mm stroke compatibility, 152.5 mm connecting rod length, and a 32.5 mm compression height, the SC7303 is available with an effective 8.5:1 compression ratio when used with an RB25DET cylinder head or 8.2:1 with an RB26DETT cylinder head. Deep valve reliefs provide clearance for high-lift camshafts and oversized valves, while accumulator grooves, double forced pin oilers and premium wrist pins improve lubrication and durability under extreme operating conditions.
Each kit includes six forged pistons, premium 1.0 mm / 1.2 mm / 2.8 mm ring sets, 21 mm heavy-duty wrist pins and spiral locks for a complete installation. Every piston is CNC machined and weight matched to tight tolerances, ensuring consistent engine balance and maximum performance. The lightweight yet incredibly strong 2618 forged aluminium construction provides excellent resistance to detonation and high cylinder pressures, making these pistons ideal for serious street, drag and circuit racing engine builds.
