Supertech VW 1.8T 20V 82.50mm Bore -17cc Dish 8.7:1 CR Pistons - Set of 4 (700HP) (Excl Rings)

If you're building a high-performance VW 1.8T 20V engine, these Supertech forged pistons are a solid choice for handling significant power. This set is designed for an 82.50mm bore and features a -17cc dish, which helps achieve a 8.7:1 compression ratio. They are rated to support up to 700 horsepower, making them suitable for serious engine builds. Remember that this set does not include piston rings, so you'll need to source those separately.

These pistons are forged from high-strength aluminum, a common material for performance pistons because it offers a good balance of strength and weight. The dish design is crucial for controlling combustion chamber volume and achieving the target compression ratio, especially when paired with different cylinder heads or head gasket thicknesses. Supertech is known for producing well-built engine components, and these pistons are designed to withstand the stresses of boosted applications. The 82.50mm bore size is a common upgrade size for the 1.8T engine, allowing for a slight increase in displacement over stock.

When installing these pistons, ensure you follow the manufacturer's recommended clearances and lubrication procedures. Because these are a performance part, it's essential to have your engine block machined to the correct bore size and finish. This set is intended for enthusiasts looking to push the limits of their 1.8T engine, and proper installation is key to achieving reliable performance. Please note that these pistons are not CARB approved and cannot be shipped to California.
