Nissan VR engine
From Wikipedia, the free encyclopedia
The VR engine is a 3.8 L V6 piston engine from Nissan. The engine is the product of further development of the widely successful VQ engine series, in particular drawing experience from the JGTC racing engines as well as Nissan's VRH engines from vehicles such as the Nissan R390 GT1.
[edit] VR38DETT
This 3.8L twin-turbo DOHC V6 engine is rated by Nissan to produce 353 kW (473 hp) @ 6,400 rpm and 588 N·m (434 ft·lbf) @ 3,200-5,200 rpm in its use in the 2008 Nissan GT-R[1]. It is so far, the only version of the VR engine in production.
The engine sports 24-valves controlled by dual overhead camshafts with variable valve timing (intake only). The block is cast aluminum with plasma-sprayed bores. The turbine housing for the IHI turbochargers are integrated into the exhaust manifold to decrease weight and bolster vehicle balance. The engine also sports a pressurized lubrication system controlled thermostatically.
The VR38DETT is hand built in a special clean room in Nissan's Yokohama facility by specially trained engineers. Each engine is assembled by only one engineer, to promote greater quality control.
It is fitted to the following vehicles.
