Supertech VW 1.8T 83mm Bore -14.8cc Dish 9:1 CR Pistons - Set of 4 (Rated 700HP) (Excl Rings)

If you're rebuilding the engine in your VW 1.8T and looking to handle more power, a set of forged pistons like these from Supertech is a solid choice. These pistons are designed to replace your stock ones and are built to withstand the demands of a high-performance setup. With an 83mm bore and a -14.8cc dish volume, they help achieve a 9:1 compression ratio, which is a common target for boosted applications aiming for a balance between power and reliability.

Supertech uses a strong forged aluminum construction for these pistons, making them significantly more durable than cast pistons. This strength is crucial when you're pushing your engine beyond its original limits, especially if you're aiming for the 700HP rating these pistons are designed for. The dish volume is specifically calculated to work with common cylinder head volumes in the 1.8T engine to achieve that 9:1 compression. Keep in mind that these pistons are sold as a set of four and do not include piston rings, so you'll need to source those separately.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and procedures. Proper installation is key to ensuring their longevity and performance. These pistons are a significant upgrade for anyone serious about building a more powerful 1.8T engine, but they are not CARB approved and cannot be shipped to California.
