Why not try calling TurboCity instead? I've heard a lot of good things about them.

I think it'd be easiest (and much cheaper) to just buy a watercoolered t3 turbo off of another earlier turbocoupe. That way you can get all the special fittings you need (like the oil return line, wastegate, special exhaust housing and turndown, etc) and still be able to send it away for a rebuild/upgrade at a later date.

I had a hybird T3/T4 custom built by Majestic Turbo in Waco, Texas. VERY nice people who know what they're doing. Ask for Kevin Draper. 1-800-231-5566

The guy doesnt know what he is talking about. A T3 with an SVO style compressor outlet is a direct bolt in to the 87-88. Only difference is the T3 specific oil drain line, and elongating the holes on the down pipe flange that bolts to the exhaust elbow.

How was Majestic Turbo, price wise? Their web page wasn't all that great. And will they sell rebuild kits for us do-it-yourselfers?
