well its pretty much impossible to give a price range because it will have to be completely one off with mostly all custom parts, and parts costs are as variable as anything in the universe. but it can be done, you might want to consider a rear mounted turbo, i'm not sure how much room there is but it could be doable, i think?
the reason i'm going with the supercharger because it's.. oh about 1/5 of the work!
