CP Piston & Ring Set for Nissan VQ35DE - Bore (96mm) - Size (+0.5mm) - CR (8.5)

This is a set of forged pistons and rings from CP Pistons, specifically made for the Nissan VQ35DE engine found in your 2003-2007 Infiniti G35 and 2003-2006 Nissan 350Z. These pistons are designed for builders looking to get the most out of their engine, whether for a performance build or a robust rebuild. They come at a 96mm bore size, which is a +0.5mm oversize from stock, meaning they're intended for engines that have already been bored out or require a larger bore for a rebuild. The compression ratio is set at 8.5:1, making them a solid choice for forced induction applications or for those seeking a slightly lower compression for reliability with premium pump gas.

CP Pistons are well-known for their strength and durability, using high-grade forged aluminum to withstand the higher pressures and temperatures of performance engines. This set includes the pistons, rings, and wrist pins, giving you the core components needed to start your engine build. The 8.5:1 compression ratio is a notable feature, offering a good balance for tuners who plan to add a turbocharger or supercharger, as it provides more room for boost before detonation becomes a concern. Remember, these are an oversize part, so ensure your engine block has been properly machined to the 96mm bore specification before installation.

When undertaking an engine rebuild with performance pistons like these, it's crucial to have all your measurements precise. Ensure your connecting rods are also checked and potentially upgraded to handle the increased power. Always refer to the manufacturer's installation instructions for specific details on ring gap, piston-to-wall clearance, and lubrication requirements to ensure a long and healthy life for your newly built engine.
