What is the purpose of an external wastegate?

An external wastegate controls the maximum boost pressure your turbocharger can produce. It diverts excess exhaust gas away from the turbine wheel, preventing over-boosting and protecting your engine.

Can I change the boost pressure on this wastegate?

Yes, the spring inside the wastegate can be swapped out to change the boost pressure. This unit comes with a 7.25 PSI spring, but other spring rates are available separately to tune your boost levels.

What else might I need to install this wastegate?

Installation typically requires a compatible turbo manifold with a wastegate flange, and a custom exhaust dump tube to route the bypassed exhaust gas. Refer to the manufacturer's instructions for specific requirements.
