GT-R Spec V : Finalized Specifications

Well at least according to this link on the Motor Trend Forums, which came from somewhere else.

"New & Future Cars: Nissan GT-R Spec V
Nissan has finalized the performance numbers on the GT-R Spec V.

Nissan's newest supercar will have a very limited production run. Unlike the stock GT-R, the Spec V will be a 2-seater, though both models will look virtually identical. Output of the GT-R's 3.8-liter twin-turbo V-6 has been increased to 520 bhp at 6500 rpm and 440 lb.-ft. of torque peaking from 3200–5200 rpm. The Spec V will be slimmer by about 200 lb., tipping the scales at 3615 lb.

"We expect the GT-R Spec V to be introduced in the U.S. sometime in early 2009, with a price tag of about $130,000 "

It should be expensive. Not too sure if its going to actually make it to the US. Time will tell
