I'm not saying it won't but dollar for dollar, its going to take a lot more modification for the 500 to handle the HP than the 518. All depends on how much money you have to spend.
I have done them all different ways and with a basically stock trans with a GOOD Rebuild Kit(Good Clutches)and a shift kit they work just as well.As long as you're half way intelligent about it(No Reverse Roll-outs or Neutral Drops)it will last quite awhile without any further Mods....
