Wiseco VW/Audi Turbo Conversion 20V Cyl Head 81.0mm Bore 8.5 CR Pistons (Inc Rings)

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This set of forged pistons is built for turbo conversions on VW and Audi 1.8L 20V engines, designed to handle the demands of serious racing builds. They feature an 81.00 mm bore and a compression ratio of 8.5:1, making them a solid choice for boosted setups where durability and performance are key.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. Wiseco has included several features to enhance performance and longevity, such as precision ring grooves, anti-detonation grooves, and additional ring seal improvements. The crown is fully machined for accuracy, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, which is crucial in high-performance engines.

This set includes four pistons, premium rings, and is designed to withstand heavy to severe duty performance applications. They fit a range of vehicles, including models like the Audi A4, Audi TT, Volkswagen Golf, and Volkswagen Jetta. Please note that these pistons are not CARB approved and cannot be shipped to California.
