I have a '90 twin turbo with 150,000 miles on it. Still on original turbos and needs some work. Brakes, torsion bars, bushings etc. Opinions wanted if I should sell it and buy a '92 or later n/a with half the miles and upgrade it or keep the tt and drop the cash into that.

 

I would get(have) both of them.... then switch some parts....like twinturbo and cooling system and then sell your car
well, if you have the money ofcourse
