whats the best?
its gonna be a daily driver car though
what kinda horses would i get out a super/turbo charger
and how strong could i build up the stock engine?

 

just strap a jet engine onto your car, that'll be safe in terms of engine damage, and hey, it'll blow away any turbo/nitrous/supercharged/NA car out there.

 

Yeah, a jet lude is definately the way to go, or run oxygen instead of nitrous. That will give you a healthy burn. Do a search of posts made by Toretto. We've went over this many times with him. If you still have a specific question after that we'll be happy to answer it.
