CP Piston & Ring Set for Nissan CA18DET Bore (84.5mm) - Size (+1.5mm) CR - (9.0) - Set of 4

This is a set of four forged pistons and matching rings from CP Pistons, designed for the Nissan CA18DET engine. These pistons are built to a 1.5mm oversize, meaning they measure 84.5mm in bore diameter, and feature a 9.0:1 compression ratio. CP Pistons are well-known in performance circles for their robust construction and ability to handle the demands of high-output engines.

Forged pistons are a significant upgrade over cast pistons, offering superior strength and durability. This is crucial for engines that have been modified for increased power, as forged aluminum can better withstand the higher cylinder pressures and temperatures. The 9.0:1 compression ratio is a common target for modified CA18DET builds, offering a good balance between pump gas drivability and the potential for increased power with tuning. The set includes all four pistons and the necessary rings, simplifying the rebuild process.

When rebuilding your CA18DET with these pistons, it's important to ensure your cylinder bores are properly honed to match the 1.5mm oversize. This set is intended for performance applications and is not CARB approved, so it cannot be shipped to California. Always refer to the manufacturer's installation instructions for precise clearances and assembly procedures.
