A buddy told me that I can use a turbo from a car like the Audi a4, that comes stock with turbo, so it will pass smog and as long as my internals are C.A.R.B., then the referee should deem it street legal. . . what are your thoughts on a setup like this? ? ? seems like it would work as the only reason greddy turbos are street legal is that they are not adjustable to gain more power. . .
