not a comparo but sticking up for the Nismo... ive driven both cars and if you know how to push a cars limits the Nismo can be pushed further than a sport packaged Z. And to push a cars limits that means VDC off. Ive upgraded my nismo and you can mod it just like a sport z but its a great head start and I gaurantee if you made the same mods to both a sport and a Niz the Nismo would gain more of an advantage with each mod.
