CP Piston & Ring Set for Nissan VG30DE - Bore (87.5mm) - Size (+.05mm) - Compression Ratio (10.5)

If you're rebuilding the engine in your Nissan VG30DE and looking for a solid set of pistons to handle increased performance, this forged set from CP Pistons is a strong contender. These pistons are designed to replace the stock ones with a slightly larger bore size, specifically 87.5mm, and are finished at a +0.05mm undersize. This means they're intended for engines that have been honed out to match this specific dimension, often as part of a performance rebuild to ensure a perfect fit and optimal clearance. The compression ratio comes in at 10.5:1, which is a common target for naturally aspirated or mildly boosted VG30DE builds, offering a good balance between power and drivability.

CP Pistons are well-known for their forged construction, which uses aerospace-grade aluminum alloys. This process creates a piston that is significantly stronger and more durable than cast aluminum, making it much more resistant to the extreme pressures and temperatures found in a performance engine. This particular set is designed to meet the demands of enthusiasts who are pushing their VG30DE engines beyond stock specifications. The included rings are also selected to work in harmony with the pistons, ensuring proper sealing for good compression and oil control.

When undertaking an engine rebuild of this caliber, it's crucial to have all your components measured and ready. These pistons are a +0.05mm size, meaning the cylinder bore should be precisely machined to 87.5mm to achieve the correct piston-to-wall clearance. Always refer to the manufacturer's detailed installation instructions and consult with your engine builder to ensure all specifications are met for a successful rebuild.
