Not content to build a 350Z GTS, Nissan may be planning an all out assault on the sports car world with a V8 powered monster rebadged as the 450Z. Pulling a 4.5 liter V8 from the Infiniti stable, this beast could produce 400 hp. There is even talk of 4 wheel drive! Presumably this car would slot in somewhere between the 350Z and the GTR.
