Hell, I had a 3000GT (not a turbo mind you) and many of those guys (with the V6 twin turbo) were running 450 hp in a street set up, and driving it regularly with pump gas. And this is on a 13 -18 year old engine. Given some of the new technology this is a very practical. And still get better gas mileage than our trucks. The only thing you are loseing is some of the low end torque, so it isn't ideal for hauling.
