RB26DETT

The VR is a twin-turbo DOHC V6 automobile engine from Nissan with displacements varying from 3.0 L to 3.8 L. An evolution of the widely successful VQ series, it draws on developments from the VRH JGTC and Nissan R390 GT1 Le Mans racing engines.

Announced by Infiniti on December 15, 2015 the VR30DDTT[1] will be first available in the Infiniti Q50 sedan and will come in a 300 hp and 400 hp version.[2]

VR38DETT

Designated the VR38DETT by Nissan, the engine is currently used in the 2007–present Nissan GT-R[4] and the limited production Nissan Juke-R.

The VR38DETT sports 24 valves controlled by dual overhead camshafts (a total of 4 cams for both overheads) with variable valve timing (intake only). The block is cast aluminum with 0.15 mm (0.006 in) plasma-sprayed cylinder liner bores. This coating provides a hard protective layer for the piston rings to slide on as the piston moves up and down during their cycles. 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 equipped with a feedback control system that changes air fuel ratio depending on the engine load which has a significant effect on reducing the fuel consumption.[5]

The VR38DETT is hand assembled in a special clean-room environment at Nissan's Tochigi facility by specially trained technicians.[6]

Since 2011 all VR38DETTs produced have come with a red top engine cover.

Fully equipped with the first set of catalytic converters, turbos, all of the engine driven accessories, front differential assembly, and turbo outlet pipes, the engine weighs 608 lb (276 kg).[7]
