http://www.turbochargedpower.com/ <---These fella's are bolting up Turbo kits on 5.0 stangs and even the 4.6 stangs with a bone stock motor with no internal building as far as I can understand on some of the cars. I was thinking about this set up on my next car but is it safe at all? They also say they're open to making a turbokit for other types of cars which would be a good add on for a 4.6 or 5.0 T-bird. Anywho I was just curious on your opinions of this set up. I don't beleive I would go beyond the stage 1 setup on a stock motor and I still have my doubts about that.
