What is the main advantage of a forged piston over a cast piston?

Forged pistons are made by heating and hammering aluminum into shape, which makes them significantly stronger and more durable. This improved strength is essential for engines running higher boost pressures or compression ratios.

How many pistons do I need to buy for a full engine set?

This product listing is for a single piston. You will need to purchase the correct quantity of pistons to match the cylinder count of your Nissan VG30DETT engine for a complete set.

Can this piston be shipped to California?

No, this piston is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Wiseco is well-known for making high-performance internal engine components, and this forged piston is a prime example of their work. Designed for Nissan VG30DETT engines, this piston features a dome with a 4.2cc volume and measures 1.260 inches in pin bore diameter and 3.464 inches in bore diameter. It's a single piston, meaning you'll need to purchase multiples to complete a set for your engine rebuild.

Forged pistons like this one are built from a solid block of aluminum that's heated and hammered into shape, making them significantly stronger and more durable than cast pistons. This strength is crucial for engines that see higher cylinder pressures, whether from increased boost or higher compression ratios. The dome shape is specifically designed to work with the VG30DETT's cylinder head configuration to achieve a desired compression ratio and combustion chamber shape.

When rebuilding an engine, especially one known for performance like the VG30DETT, using well-built components like these Wiseco pistons is key to a reliable and powerful outcome. Remember that this piston is not CARB approved and cannot be shipped to California.
