well considering you say hf, and your name says b18, im guessing its a stock hf, and if so, why in gods name would you want to anything but throw that engine and tranny in the river? i mean, im sure you could get it to work, but why would you want to use the stock turbo off a saab? hell a stock turbo period. i cant remember what it is, something about bearings or some shit, but they dont have em, which makes them poopy.
