Product Description

The Turbosmart TS-0552-1012 GenV WG40 CompGate40 external wastegate is a high-performance mechanical wastegate engineered for precise boost control on turbocharged engines. Designed as a universal external solution, it offers superior flow capacity, thermal handling, and reliability for both street and motorsport applications. It's ideal for enthusiasts, tuners, and race teams looking to improve boost response and maintain consistent pressure under high load.

Featuring a 40 mm valve and a modular diaphragm design, the wastegate provides adjustable actuator orientation for flexible installation in tight engine bays. The collar-locking system simplifies spring changes, and the included spring kit allows tuning for a wide range of boost pressures. Strap-type V-band connections and optional liquid actuator cooling make it durable and versatile for most turbocharged setups. Because this product is universal, fitment depends on turbo plumbing rather than a specific vehicle model.
