I agree that mod for mod the GTR will always be quicker mostly because of the 4WD launch, but there isn't that much difference in engine capability. GTR's run 1.1 bar in stock form while 2WD Skylines typically run .6 bar in stock form. Just the difference in boost almost accounts for the horsepower difference. I live in Japan and there is just as much of a following for 2WD Skylines (mostly because of the drift scene) as there is for GTR's and you see just as many 900 and 1000ps 2WD Skylines as you do 1000ps GTR's.
