I'm no racer or know much about cars in general, but I have read thru enough threads and stayed at a Holiday Inn Express once. First off, your better off swapping an srt6 motor rather than trying to build the equivalent with the N/A motor. The parts you would need to convert would probably be more $ than just buying a used srt6 motor outright. Not to mention the time and effort installing all those parts. Second, I've read phantom grip does offer something that acts like a LSD and is made for our cars for only $500.00. Good luck man, hope I helped.
