CP Piston & Ring Set for Nissan VG30DETT - Bore (88.0mm) - Size (+1.0mm) - Compression Ratio (8.5)

If you're rebuilding the engine in your Nissan VG30DETT, especially for a performance application where you're pushing the limits, a strong set of pistons is crucial. These forged pistons from CP Pistons are built to handle the increased stress and heat that come with a modified or high-performance engine. They are designed to be a direct replacement for the stock pistons, but with the durability and strength that forged aluminum offers over cast or hypereutectic designs.

Forged pistons start as a single block of aluminum that's heated and hammered into shape under immense pressure. This process aligns the grain structure of the metal, making them significantly stronger and more resistant to detonation and fatigue than cast pistons. This particular set is sized at 88.0mm with a +1.0mm overbore, which is common when an engine block needs to be machined to clean up cylinder walls or account for wear. The 8.5:1 compression ratio is a good choice for boosted applications, providing a bit more room for boost pressure before detonation becomes a major concern, while still offering solid performance on pump gas.

This set includes the pistons and rings, ready for installation after your machine shop has prepared the cylinders. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and break-in procedures.
