Congrats!
I see from you side on pic, that you are also rinning the GT TB. Do you have a separate plate behind it to hold the gasket tight to the UIM? as you probably realise that the GT TB doesn't have the hump on the top of the flange like the SVT TB does, and so, if it doesn't press against the gasket to seal it to th UIM, you may get boost leaks from there. I myself had a friend TIg an extra piece of Aluminum to the top of my GT TB to create the "hump" and thus seal the TB to the UIM.

I have to post pics again of my set. My discharge pipe look 200% better than the last one!

PS that BOV is the RFL, correct? So is it ReallyFugginLoud?

It looks as if he's made a flat steel adapter plate of some kind behind the TB judging by the first pic. I'd still be worried about the gasket flapping in the breeze though until it was welded to the TB like yours Stazzi, or at least a thicker adapter plate.

Very nice work Tom! I need a ride. Let's see... how many hours drive is it to Texas...

Stazi and Brad:
Yes it is a GT high perf. TB from MAC, a 70mm. I used a fairly thick, rigid piece of aluminum sheet to cut an adapter plate. It would take more than 10-12 psi I intend to run to separate that. Just trust me on that one. There are no extra fittings on the MAC like there are on the stock 65mm TB's.

You like my "home-boy" intake pipe? I even painted it to forestall the comments that your pipe brought!

Brad, if you can get here then you can ride in it.
