Product Description

The Turbosmart TS-0552-1202 GenV CompGate40CG 5 PSI external wastegate is a high-performance boost control component engineered for turbocharged applications requiring precise low-pressure control. Its compressed gas (CG) diaphragm design is optimized to handle high top chamber pressures such as those seen in CO2 or compressed air systems, enhancing diaphragm longevity and consistent boost control under demanding conditions. This universal external wastegate is suitable for most turbo systems with an external wastegate port.

Featuring a 40 mm valve, a modular mechanical diaphragm actuator, and a 360° adjustable actuator orientation, this wastegate offers flexibility for installation in tight engine bays or custom layouts. The inverted diaphragm and advanced design provide excellent thermal and flow performance, while the included strap-type V-band connections and spring kit allow for boost tuning across a range of pressures. The TS-0552-1202 is ideal for performance builders, racers, and tuners seeking reliable, consistent boost management in street, track, and competition applications.
