Product Description

The Turbosmart TS-0552-1011 GenV WG40 CompGate40 external wastegate is a high-performance mechanical wastegate designed for universal applications with turbocharged engines. Developed as a next-generation upgrade over Turbosmart's Gen4 series, this wastegate offers industry-leading thermal performance and superior flow characteristics for both street and motorsport use. It's ideal for tuners, racers, and enthusiasts looking to control turbo boost levels precisely and reliably.

Featuring a 40 mm valve diameter, a modular actuator design, and a unique collar-locking system, this wastegate allows easy orientation and spring changes to suit different boost targets. The TS-0552-1011 comes pre-fitted with a 14 psi spring and includes additional springs for flexibility. Its robust stainless steel construction, strap-type V-band clamps, and optional liquid actuator cooling provision make it durable under high heat and pressure. Because it is universal, fitment depends on your turbo system plumbing rather than a specific vehicle model.
