I've been tossing around the same thing recently since I finished a customers turbo 93 Cobra, full acessories including A/C and 700hp with low boost, what more could you ask for. Well I can tell you even the kit I installed on his needed some attention to have it fit properly, and you hear that about most kits.
Although I have my own shop, am very proficent with a TIG and MIG, plasma cutter, mill and bender it will still take many hours to custom fab a kit, and have it fit and function properly. You need to think about the future with your car as well, the tiny T3/T4 turbo will not support large power (although as mentioned above enough to break a stock block) The proper tubing can be bought from
RacePartSolutions - Fast Parts At Discount Prices and if your going to try to make our own manifolds most header compnaies offer box of bends and flanges, mine will come from
Stahl Headers - Manufacturing racing exhaust headers and camshafts. The header/manifold portion is very important and most guys can't build one that functions properly, they is a lot into the headers...do your research. The entire system with it's bends is truly thought out or you slow down the air or create so much back pressure at the turbo which causes other issues.
I suggest you do more reading over at Turbomustangs and maybe look at the B&G or Pony Down hot and cold side kits....
Hey XP, my project may involve a mod motor
