The VR38DETT engine

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.

VR38DETT

This 3.8L twin-turbo DOHC V6 engine is rated by Nissan to produce 485 PS (357 kW; 478 hp) at 6,400 RPM and 60 kg·m (588 N·m; 434 ft·lbf) at 3,200-5,200 RPM in its use in the 2008 Nissan GT-R[1]. With turbos, the motor weighs 608lbs.[2] 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 0.15 mm plasma-sprayed cylinder liner bores. The turbine housings for the two IHI turbochargers are integrated into the exhaust manifolds to decrease weight and bolster vehicle balance. It also makes it harder to install larger turbochargers to increase performance as two new exhaust manifolds are needed. The engine also sports a pressurized lubrication system controlled thermostatically.

The VR38DETT is hand assembled in a special clean room in Nissan's Yokohama facility by specially trained technicians. Each engine is assembled by only one technician, to promote greater quality control.

It is fitted to the following vehicles.
