CP Piston & Ring Set for Nissan CA18DET - Bore (83.5mm) - Size (+0.5mm) - CR (8.5)

Forged from high-strength 2618 aluminum alloy, these CP Pistons are built to handle the demands of a performance Nissan CA18DET engine. The 83.5mm bore size, which is 0.5mm over the stock dimension, is ideal for rebuilding an engine with a worn cylinder wall or for achieving a slight displacement increase. This set is designed for a compression ratio of 8.5:1, making it a solid choice for boosted applications where controlled combustion is key.

CP Pistons are known for their robust construction and precision machining. Each piston in this set features a specific skirt design and wrist pin arrangement to minimize friction and ensure smooth operation, even under high cylinder pressures. The included rings are matched to the pistons for a proper seal, which is critical for maintaining compression and preventing oil blow-by. This set is intended for builders looking to establish a strong foundation for a performance engine build, whether for track use or spirited street driving.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Proper ring gap setting and cylinder wall preparation are essential for optimal performance and longevity. This set is not CARB approved and cannot be shipped to California.
