What is the purpose of a wastegate?

A wastegate controls the maximum boost pressure your turbocharger can produce. It diverts exhaust gas away from the turbine wheel once a set pressure is reached, preventing overboost and protecting your engine.

Can I change the boost pressure on this wastegate?

Yes, you can change the boost pressure by swapping the internal spring. This unit comes with a 1.5 Bar (21.75 PSI) spring, but other spring pressures are available separately from TiAL Sport.

What else do I need to install this wastegate?

Installation requires custom exhaust fabrication for the wastegate dump tube and plumbing to connect it to your turbo manifold and the wastegate actuator port. You will also need appropriate V-band clamps and flanges.

Product Details

The MVS wastegate uses a 38mm diaphragm and comes with a 1.5 Bar (21.75 PSI) spring installed, ready to manage boost on your turbocharged setup. This well-built unit is designed to help you dial in precise boost control, preventing overboost situations and keeping your engine running safely within its intended parameters. The compact size makes it easier to fit into tight engine bays, a common challenge with aftermarket turbo systems.

TiAL Sport is known for making solid components for forced induction applications. This wastegate features a billet aluminum actuator housing and a stainless steel diaphragm. The internal spring is made from high-grade stainless steel, ensuring consistent performance over time and across a range of temperatures. The purple anodized finish on the actuator housing not only looks sharp but also adds a layer of protection against corrosion.

This wastegate is not CARB approved and cannot be shipped to California. Ensure you check local emissions regulations before purchasing.
