CP Piston & Ring Nissan RB26DETT - Bore (87.0mm) - Size (+1.0mm) - CR (8.5) Single Piston

This is a single forged piston from CP Pistons, specifically made for Nissan RB26DETT engines. It features an 87.0mm bore, which is 1.0mm oversize from the factory specification, and a compression ratio of 8.5:1. This piston is designed for builders looking to refresh or upgrade their RB26 engine, often used in performance builds where increased displacement or replacement of worn components is needed.

CP Pistons are known for their well-built construction, and these forged pistons are no exception. Forging makes the aluminum stronger and more durable than cast pistons, which is important for engines that see higher cylinder pressures and temperatures. The 8.5:1 compression ratio is a common target for modified RB26s, offering a good balance for forced induction setups without being too aggressive for pump gas in many applications. This specific piston is 1.0mm larger than stock, allowing you to bore your cylinders out to match if they are worn or if you're aiming for a slight increase in displacement.

Please note that this piston is not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly.
