Turbosmart 2011 WG38/40/45 7PSI Outer Spring Brown/Pink

If you're looking to fine-tune your turbo system's boost pressure, swapping out the wastegate spring is a common way to do it. This is the outer spring from Turbosmart, rated at 7 PSI, designed to work with their WG38, WG40, and WG45 external wastegates, as well as their IWG-75 internal wastegate actuators.

Turbosmart makes these springs from well-built materials to ensure they hold their tension and perform consistently, even under the heat and pressure of a turbo system. By changing this spring, you can adjust the point at which your wastegate opens, which directly affects the maximum boost your turbocharger will produce. This particular spring is a 7 PSI option, often used to raise boost levels from a stock setting or to match a specific tuning goal.

Remember, this spring is not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual or consult with a professional tuner to ensure this spring rate is appropriate for your specific application and supporting modifications.
