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

This listing is for a single CP Pistons forged piston and ring set designed for the Nissan RB25DET NEO engine. It includes one piston, a set of rings, wrist pin, and locks, all ready for installation. This set is specifically sized at 87mm bore and is 1.0mm oversize, intended for engines that have been bored out to accommodate larger pistons. The compression ratio is set at 9.0:1, which is a common target for builds looking for a balance between performance and pump gas compatibility.

CP Pistons are well-known for their robust construction, and this forged piston is no exception. Forged from high-strength aluminum alloy, these pistons are built to withstand the increased cylinder pressures and temperatures common in performance applications. The 1.0mm oversize means this piston is meant for an engine block that has already been machined to this larger diameter, typically during a rebuild or performance upgrade. The included rings are designed to seal effectively against the cylinder wall, ensuring good compression and oil control.

When installing this piston set, ensure your engine block has been properly machined to the 87mm bore size. It's always a good idea to consult the manufacturer's installation instructions for specific details regarding piston placement and ring gapping. This set is a solid option for rebuilding or upgrading your RB25DET NEO engine.
