Now you are just looking for trouble. Nissan had to choke the GTR to get it legal in Japan, sound farmiliar? A balls out contest between an r34 and 03 cobra, both modded on stock internals would be a fight I wouldn't want to have to bet on. Both in a straight line and a corner.
Spend a little time researching the skylines, and you will realize what the rest of the world already knows. They are the best production car to never be imported to the US. Period.
