This is a set of six forged pistons and rings from CP Pistons, specifically made for Nissan RB30 and RB25DET engines. These pistons are designed for a standard 86mm bore and feature a compression ratio of 8.2:1, making them a solid choice for builds looking for reliable performance without excessive compression. CP Pistons is well-known for producing strong internal engine components, and this set is built to handle the demands of a performance RB engine.

Forged pistons like these are significantly stronger than cast pistons, which is crucial for engines that see higher boost levels or more aggressive tuning. The 8.2:1 compression ratio is a versatile figure, offering a good balance between power and drivability, and it leaves room for boost without being overly sensitive to fuel quality. This set includes the necessary rings to complete the piston assembly, ensuring you have the core components ready for installation. When rebuilding or upgrading your RB engine, using well-made pistons is a key step in ensuring long-term reliability and performance.

This set is intended for the RB30 and RB25DET engine platforms. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or a qualified mechanic to ensure these pistons are the right fit for your specific build goals and to follow proper installation procedures.
