CP Piston & Ring Set for Nissan RB26DETT - Bore (86.0mm) - Size (STD) - CR (9.0) - Set of 6

This is a set of six forged pistons and rings from CP Pistons, specifically made for the Nissan RB26DETT engine. These pistons are designed for an 86.0mm bore, which is the standard size for this engine, and they feature a 9.0:1 compression ratio. If you're rebuilding or modifying your RB26DETT, especially for higher performance levels, a well-built set of pistons like these is crucial for handling increased cylinder pressures and temperatures.

CP Pistons are known for their robust construction, and this set is no exception. They are forged from high-strength aluminum alloy, which makes them significantly stronger and more durable than cast pistons. This strength is essential for engines that see hard use, whether it's for track days, spirited driving, or just a reliable street build. The 9.0:1 compression ratio is a popular choice for many RB26DETT builds, offering a good balance between power output and pump gas compatibility, though tuning will be critical to realize its full potential. This set includes the pistons and the necessary rings to match, simplifying your parts acquisition for the engine build.

When installing these pistons, proper balancing of the rotating assembly is always recommended to ensure smooth operation and longevity. It's also important to ensure your cylinder walls are perfectly honed to the correct cross-hatch pattern for optimal ring seal. Remember that this piston set is not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic for specific installation procedures and tuning recommendations tailored to your build.
