GTM Performance Engineering: MHI Twin Turbo Official Release

Sounds like you are going with the exact same setup as myself

Is anyone else here going to need to have the BOV's recirculated (plumbed back)?

I know that I mentioned this to Mike a while back and he said that they would have an option for it because others had already asked about it but he didn't elaborate on what it would be. I don't believe that the standard Tial Q or Turbosmart Raceport BOV's can be recirculated so I would assume that they will send either the Tial QR or the Turbosmart Plumb Back.

Does anyone know more about this?

will there be boost creep issues with the .64ar running 2.5" all the way back, no cats?

It's entirely possible if you're planning on using internal wastegates. Either go external or step up a turbo size and you won't have to worry about it.

By step up a turbo size your reffering to like from .64 to .84?? Don't flame me I'm still in the learning process lol
