you'll need fuel managment... you could use a 12:1 FMU but don't reccoment going over 7-9lbs... stock injectors may even hold up to a small turbo, but DSM 450cc's are cheap.
I have both DSM 450's and an FMU along with a turbo manifold/downpipe and turbo I could get rid of if someone brought cash
You would be missing IC piping, IC and bolt up your exhaust you would be done.
