Features & Product Details

SteamSpeed has worked hand and hand with Turbosmart to develop the line of Billet Pro Wastegates. This is an internal wastegate actuator that will provide more precise boost control when compared to the OEM wastegate actuator. The end result is a flatter and more stable boost curve with less boost drop at peak RPM. You will get better turbo response, improved throttle response, and less turbo lag.

The SteamSpeed internal Wastegate has been crafted using quality billet materials, and it will be able to handle extreme temperatures along with high boost levels for prolonged periods of time. And since it is adjustable, you can change the springs for a variety of boost levels. 

This wastegate will come in an anodized black finish and will come ready to install on your application. 

Note that this is for those equipped with the USDM Single Scroll option. 

Actuator will not work with Subaru OEM IHI Turbos.

QUESTIONS & ANSWERS

  • Q: 2017 Sti fitment   JoshD1 year ago

    Will this fit the 2017 Sti turbo? I believe it’s the VF48 turbo that the 2017 Sti has if I’m not mistaken.

      A:  This model is for aftermarket turbos with Mitsubishi style turbine housings. Most aftermarket turbos are MHI style. We make a different model specifically for IHI VF turbos. https://www.rallysportdirect.com/part/wastegates/sti-wg-pro-vf-steamspeed-billet-adjustable-wastegate-pro

  • Q: Springs?  Ruination3 years ago

    How is it adjustable? Comes with multiple springs?

      A:  You will adjust the length of the wastegate rod on the wastegate itself. This will only come with one spring.

      A:  The ring on the cap screws off. The actuator has 3 slots for different sized springs which come in a variety of preloads, so you can have 1-3 springs installed at once to fine tune the exact preload. SteamSpeed "pro" actuator springs or TurboSmart IWG springs both will work. Yes, you can also shorten the rod by a mm or 2 to gain an extra 0.1 bar of preload too.
