I got some intake manifold questions: (and yes i'm going to do the a6 IM conversion in the near future).

H23:
- What throttle bodies will fit the h23 intake manifold? F22a1, a6, H22a?

- The h23 upper IM is a direct bolt on to the lower f22a6, correct?
- Why is it more beneficial to do this hybrid manifold? is it just the throttle body, or is there more power in the design?
- Does the fuel rail bolt right up?
- Will i need the TPS?
- can i swap the IACV and EGR valve from the f22a6 onto the h23?


h22:
Will the H22A intake manifold fit the the upper half of the f22a6 (bottom half)?


I think that's about it. thanx in advance for all your help.
