can you even run 2-3lbs of boost on a turbo?
Zetecs can handle around 8lbs of boost with no problem as far as I know...of course you're gonna need bigger mAF, injectors and a chip for tuning but thats automatic for any FI setup.
Never would you build a turbo setup without those because you couldn't run any noticeable boost without it...
but just like Seawulf said, read the turbo FAQ. I believe I have learned quite alot from looking around the internet for turbo info.
