"The 3.5L VQ V-6 offers some serious upgrades: an excellent infinitely variable valve timing system, a first to the VQ family and, Nissan's engineers claim, the world's first variable valve timing to use electromagnetic control of camshaft phasing."

I believe it's the "electromagnetic control of camshaft phasing" that's generating the extra horses in the G35 and 350Z. If this is in fact controlled by a "computer" then a simple change in the program would easily generate 20-30 more horses.
