Yeah given that Nismo is a tuning house.............
More just Nissans motorsport division. Production car is touchy as they are only making 20. But just look at the damn thing!! its quicker than a Ferrari Enzo at a fraction on the Enzo's price tag. This is the pinnicle of Japanese tuning. Theres not much you'd need to do to this to make it unstoppable. In fact turning up the boost a bit it probably about it... as these are only 600BHP max I think theres is a 500BHP version as well. I reckon you'd want 700BHP to be happy in a GTR as good as that.
Unfortunately all are pre sold, can't even get ya hands on a NUR edition. Pretty much all ya can hope for is a V Spec II, still worth the lotto ticket!!!
