http://www.tccoa.com, it's THE thunderbird forum, I never frequent it however, I go to
http://www.sccoa.com (it's a supercoupe forum).
I'm not even registered on tccoa I don't think....
if I were you, I'd probably go with a 302 swap, way easier and cheaper on parts then the 2.3 turbo, though there's heaps and heaps of 9 second boosted Birds and Cougars with those motors...
it was just an exspensive motor parts wise due to lack of demand and design. I'm lucky and the 3.8 used in my car shares a lot of parts with a NA 3.8, come to think of it, for more power and a daily driver temperment, perhaps you should look for the SC motor as oppossed to the 2.3, it's sure to be easier to put in and not have to worry about all the accessory drives. (maybe, it does use a DIS ignition system, could be a wiring nightmare, best advice is to search and ask those with experience in the matter)
have fun!
ps- What brought you to NICO anyway? Being a fellow Ford owner and all...
