My friends and I were discussing why they had changed it for this application. Probably something to do with the same reason it took the US years to get the STI and EVO. But that’s a story for another time.[/quote]
It’s purely economics of scale. The VQ is already established across Nissan’s entire line-up, from the sports coupe 350Z to the sedans Altima and Maxima, the crossover Murano and even the mid-sized Frontier pickup. That includes many chassis designs to fit the engine, particularly the front-midship which is on the 350Z and other sports cars, and is the darling of Nissan engineering.
The RB, being inline, would require a much longer engine bay, and the resurrection of a whole new chassis design. The new GT-R would cost so much more, that Nissan could never make their money back using the superior engine.
Instead, they could just put a twin-turbo, four wheel steering and all-wheel drive onto a 350Z and call it the US GT-R. Much more sensible.

Definitely impressive. Don’t get me wrong, I love the VQ, and it does make gobs of torque. In fact, it produces the same max torque as the RB engine at their stock tuning.
But the VQ is also one liter larger and 300 lbs heavier, despite being an aluminum block compared to the RB’s cast iron. This is progress??
And that brings us to the question of tunability, where the RB is proven up to 600hp on stock internals and 1300hp with reinforcements. I highly doubt the aluminum VQ could handle that kind of power, though I do believe that time will tell, as this is the present/future of Nissan Motorsports.
