I'd say the limit for most street cars before you start getting into the completely fugging nuts category is 650-700 depending on weight. AWD eliminates most traction issues, and you see more and more performance-viable AWD systems out there. Wait for the new GTR, that thing is going to be a modder's DREAM.

I am also positive that neither we nor they yet know what these new engines will end up in....
And all this you see here is hoping, and wishful-thinking-discussion, IMHO -- and there's nothing wrong with a bunch of enthusiasts doing just that!
I hope it will still have alot of potential.
