Re: A2 GTI throttle body and intake manifold q's (iluvfastcarz)
Other than facing the wrong way (I know why you want that though) the A2 intake and TB will be at least as restrictive as the stock 87-90 Fox intake. You could realize some gains with a Neuspeed or Audi 5K TB, but the Audi one is not a bolt on. I think the coldstart will end up pretty close to the battey if not hitting it. You may also need a longer coldstart line. For doing what your thinking about, you may not need the coldstart anyway. The aux.air regulator will not have a place to mount either, but you won't be needing that for your app.
The cable comes up slightly short I think.
