CP Piston & Ring Set for Nissan RB26DETT - Bore (86.5mm) - Size (+0.5mm) - CR (9.0) - Set of 6

If you're rebuilding the heart of your Nissan RB26DETT, especially for a performance build where you're pushing the limits, a solid set of pistons is crucial. This set from CP Pistons is built for that purpose, offering a robust upgrade over stock components. They're designed to handle the increased stress and heat that come with a modified engine, ensuring reliability when you need it most.

These pistons are forged from high-strength aluminum, a process that creates a denser, more durable material compared to cast pistons. This makes them significantly more resistant to deformation and failure under high cylinder pressures and temperatures. The bore size is 86.5mm, which is a +0.5mm overbore from the factory specification, typically used to clean up cylinder walls or achieve a specific displacement. With a compression ratio of 9.0:1, these pistons are well-suited for boosted applications, offering a good balance between power and detonation resistance. The set includes six pistons and their corresponding rings, ready for installation.

When rebuilding an engine, especially a high-performance one like the RB26DETT, attention to detail is key. Ensure you have all the necessary machine work done to spec before installing these pistons. This includes proper cylinder honing and checking clearances according to CP Pistons' specifications. Having the right tools and a clean workspace will make the installation process smoother and contribute to the longevity of your engine build.
