Would depend on the size of turbo id imagine. The bolt on Evo turbos FP make use an 3.25" anti surge inlet their largest bolt on turbo the black which is an 82mm compressor (GT35 territory) yanks are pulling 750+ "American hp" outta these badboys & 8 second passes (I think) So I guess it would be fine for anything upto GT35... Any bigger than that im not so sure.
