Honestly, If you're gonna drop $5k on forced induction, go with a Magnacharger or front mount turbo from Trick or KBRacing. I've seen a few ProCharged systems that looked great on paper, but failed when it came time to perform. Then again, I have also seem some set-ups that rock (namely Mustangs).
There are deals to be had with some used MP112s and turbo kits coming off of trucks who's owners are changing set-ups.
