Nissan VR engine

The VR is a 3.8 L twin-turbo DOHC V6 automobile engine from Nissan. An evolution of the widely successful VQ series, it draws on developments from VRH JGTC and Nissan R390 GT1 Le Mans racing engines.

Designated the VR38DETT by Nissan, the engine is currently only used in the 2007–present Nissan GT-R.

VR38DETT

The VR38DETT 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.

Fully equipped with the first set of catalytic converters, turbos, and turbo outlet pipes, the motor weighs 608 lb (276 kg). It is currently the only version of the VR engine in production.
