CP Piston & Ring Set for Nissan VG30DE - Bore (87.5mm) - Size (+.05mm) - Compression Ratio (8.5)

This is a complete set of six forged pistons and matching rings from CP Pistons, designed for the Nissan VG30DE engine. You get everything needed to outfit your engine with these performance-oriented pistons, which feature a specific 87.5mm bore and a 8.5:1 compression ratio. This setup is ideal for builders looking to refresh or upgrade their VG30DE, especially those aiming for a balance between power and reliability.

CP Pistons are well-known for their robust construction, and these are no exception. Forged from high-strength aluminum alloy, these pistons are built to handle the increased stresses of performance applications compared to cast pistons. The 8.5:1 compression ratio is a solid choice for naturally aspirated builds or those running moderate boost, offering a good compromise between low-end torque and high-RPM power. The included rings are specifically matched to the pistons and bore size, ensuring a proper seal for optimal performance and engine longevity. This set is sized at +0.05mm over the standard bore, which is important to note if you're re-boring your cylinders.

When rebuilding an engine with these pistons, it's crucial to ensure your cylinders are precisely machined to the 87.5mm bore size, accounting for the +0.05mm sizing. Proper ring gap setting and piston-to-wall clearance are critical for performance and durability, so always refer to CP Pistons' specific installation guidelines. Keep in mind that this kit is not CARB approved and cannot be shipped to California.
