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

Forged from high-strength aluminum, these CP Pistons are built to handle the demands of a performance Nissan RB25DET engine. This set is designed for an 87mm bore and comes at a +1.0mm oversize, meaning it's intended for engines that have been bored out to accommodate this size, often during a rebuild or performance upgrade. The 9.0:1 compression ratio is a solid choice for many boosted applications, offering a good balance between power and reliability.

CP Pistons are well-known in the performance world for their robust construction. These pistons are forged, a process that creates a stronger, more durable part compared to cast pistons, making them a popular choice when you're pushing an engine beyond its stock limits. This particular set is for a single piston, so you'll need to order the correct quantity for your engine build. They are designed to fit right into a prepared RB25DET block.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your RB25DET and need reliable, strong pistons, this set from CP Pistons is a well-built option.
