I was going off of this quote from Automobile Magazine:
"What we do know is that the GT-R will be Nissan’s modern equivalent of the mid-1980s Porsche 959: a staggeringly fast, all-wheel-drive, technology-laden flagship coupe into which Nissan engineers and designers have poured their souls. Sources report that the 2008 Skyline will be built on a unique all-wheel-drive platform and powered by a twin-turbo version of the 350Z’s 3.5-liter V-6, possibly bored out to 4.0 liters. The grapevine speaks of 450 hp allied to Nissan’s next-generation, variable-torque-split, ATTESA E-TS all-wheel-drive system. We say, how about a 500-hp, twin-turbo version of the 4.5-liter Infiniti V-8, instead?"
For $70k, it had better be in the 450-500 hp range to even raise an eyebrow in America.
