Nissan VQ engine


The VR is a series of twin-turbo DOHC V6 automobile engines 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.

DDTT series[edit]


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] It is on the Ward's 10 Best Engines list for 2017.


  • Aluminium block with arc sprayed mirror coating to cylinder bores
  • Aluminium cylinder head with integrated exhaust manifold
  • Lightweight resin intake and lower oil pan
  • Compact twin direct-mount turbos with electronic wastegate actuator
  • Twin water-to-air charge coolers with one (300 hp)/two (400 hp) water pumps
  • Electronically controlled variable displacement oil pump
  • Intake: electronic variable Valve Timing Control (VTC)
  • Exhaust: hydraulic continuously variable VTC



Production of the VR30DDTT engine began in 2016 at the powertrain plant in Iwaki, Fukushima, Japan.[4][5][6]

Designated the VR38DETT by Nissan, the engine is currently used in the 2007–present Nissan GT-R[7] and the limited production Nissan Juke-R.

The VR38DETT features 24 valves controlled by dual overhead camshafts (2 per cylinder head) with variable valve timing on the 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 features 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.[8]

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).[9]

Other pertinent features of the VR38DETT include:

  • Continuously variable valve timing control system (CVTCS) on intake valves
  • Aluminum cylinder block with high-endurance/low-friction plasma-sprayed bores
  • Iridium-tipped spark plugs
  • Electronic drive-by-wire throttle
  • Pressurized lubrication system with thermostatically controlled cooling and magnesium oil sump
  • Fully symmetrical dual intake and low back-pressure exhaust system
  • Secondary air intake system to rapidly heat catalysts to peak cleaning efficiency
  • 50 State LEV2/ULEV



VR38DETT NISMO Engine Tuning Menu Concept (2016)[edit]

It is a version of VR38DETT engine used in Nissan GT-R, with GT3-spec cam shaft, connecting rod and connecting rod bolt, intercooler, intercooler piping, turbocharger; NISMO 1st and 2nd catalyzers, titanium muffler.

The engine was unveiled in 2016 Tokyo Auto Salon.[11][12]


The VR38DETT is hand assembled in a special clean-room environment at Nissan's Tochigi facility by specially trained technicians.[13]
