What is the primary function of this wastegate?

This external wastegate controls the maximum boost pressure your turbocharger can produce. It does this by diverting exhaust gases away from the turbine wheel when a set pressure is reached, preventing over-boosting.

What does the 14psi spring setting mean?

The 14psi spring is the base boost pressure the wastegate will target. When the exhaust pressure acting on the wastegate diaphragm exceeds the spring pressure, the wastegate will open to bypass exhaust gas.

Can I change the boost pressure later?

Yes, you can change the boost pressure by swapping the internal spring. Turbosmart offers different spring rates separately, allowing you to tune your boost levels to your specific needs.

About this part

Product Details

The Nitronic 60 valve guide and high-temperature 347 stainless steel body construction means this Turbosmart WG38 Gen V Ultragate 38 wastegate is built to handle the heat and stress of forced induction. This 38mm external wastegate comes pre-set with a 14psi spring, offering a cost-effective way to manage boost pressure on a wide range of turbocharged vehicles. Its motorsport-proven design ensures reliable performance when you need it most.

Turbosmart has engineered this wastegate for excellent flow characteristics, validated through CFD and bench testing, which helps maintain consistent boost levels. The traditional 3-bolt flange and orientation make installation straightforward on many turbo manifolds, and the 17/7 PH stainless steel springs are chosen for their fatigue resistance, ensuring long-term operation. You can also add an optional position sensor for advanced boost control or a liquid actuator cooling option if your application runs exceptionally hot.

This wastegate is a solid option for enthusiasts looking to upgrade their boost control system. Please note that this part is not CARB approved and cannot be shipped to California.
