This 3.8L twin-turbo DOHC V6 engine is currently only used in the Nissan GT-R[1]. Fully dressed with the first set of catalytic converters, turbos, turbo outlet pipes, the motor weighs 608 lb (276 kg).[2] It is currently 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 (0.006 in) 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. The engine also sports a pressurized lubrication system controlled thermostatically.
The VR38DETT is hand assembled in a special clean-room environment at Nissan's Yokohama facility by specially trained technicians. Each engine is assembled by only one master technician("Takumi").
It is fitted to the following vehicles.
