To install a turbo kit on the Ford 3.8L would be a substantially huge job and would take considerable amounts of automotive technical knowledge and money. On top of that, you would have to beef everything up including your trans which would explode with any amount of good power.
As for my VR4, it is quicker and fun to drive, but I wouldn't consider it to be all that fast. It just all depends the environment your in I suppose. With the people I hang out with I have one of the slower cars as even a couple of them have 700+hp VR4's, and even one guy with a 850 wheel horsepower 300ZX with NO spray. Then, there are some people, who including me, also drive a SL 3000gt as a daily driver or while they are working on their VR4.
