CP Piston & Ring Set for Nissan RB25DET NEO - Bore (87mm) - Size (+1.0mm) - CR (9.0) - Set of 6

CP Pistons is well-known for making strong, reliable forged pistons for performance applications. This set is specifically for the Nissan RB25DET NEO engine, offering a +1.0mm oversize bore at 87mm, with a 9.0 compression ratio. This is a set of six pistons, designed to handle the demands of a performance-built engine.

These pistons are forged from high-strength aluminum alloy, a common choice for performance engine builds because it offers a good balance of strength and weight. The 9.0 compression ratio is a solid choice for many RB25DET builds, providing a good increase in power without being overly sensitive to fuel quality. The +1.0mm oversize means these are intended for an engine that has already been bored out to accommodate them, typically during a rebuild where the cylinders might have been slightly worn or to achieve a specific displacement.

This set includes the pistons and rings, ready for installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a successful rebuild, ensure your machine shop is aware of the exact bore size required for these +1.0mm pistons and follow all manufacturer guidelines for installation and break-in.
