EFI throttle bodies + update on my project

That is an NA throttle body and will not bolt up at all to your
manifold. However if you can find a round KH TB it WILL bolt up, but
will leave the old ISV/WG line dead, and you'll have to replumb those
lines (which you have to do with the KH manifold anywho). Talk to Chris
Semple at Force5 (www.force5auto.com), I was in the area so I stopped to
see what he had, and he just yanked me one off the shelf.

Will it work on my stock MC manifold, and should it clear the fuel rail? If not does anybody (especially in South Florida) have any leads on a round KH style one?

Tomorrow I'm going to try and find some room somehow, maybe tap a depression into the rail at that point where its tight, or maybe shave a few mil off the michelin man, maybe both. I used Porsche OEM equipment for everything except the rail itself (eg. injector cups, regulators, pressure test fitting) cut from some Porsche 944 rails I had laying arround the shop. Kinda ironic, an Audi made part designed for a largely Audi Porsche going on an Audi.
