Wiseco Volks 2.0 9A 16v Dished -11cc Turbo 83mm Piston Shelf Stock Kit

If you're building a high-performance 2.0L 16V engine for your 1990-1992 Volkswagen Golf or Jetta, especially for turbo applications, these Wiseco pistons are a solid choice. They're designed to handle the demands of serious racing and heavy-duty builds, offering improved strength and durability over stock components. The dished crown design, with a -11cc volume, is specifically intended for turbocharging, helping to achieve optimal compression ratios for boosted engines.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, a material known for its excellent tensile strength, which is crucial for pistons that experience high pressures and temperatures. They feature precision-machined ring grooves, anti-detonation grooves, and enhanced ring sealing features to ensure a tight seal and prevent detonation. The piston crowns are fully machined for a clean, consistent surface, and the forced pin oiling system helps keep the wrist pin lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating reduces friction, resists seizure, and contributes to quieter operation, making these pistons well-suited for both performance and longevity in demanding builds.

This kit includes a set of four pistons, each with an 83.00 mm bore and a 29.77 mm compression height, along with 0.787-inch diameter pins. Remember that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation guidelines carefully.
