VR35DDTT

The VR35DDTT was announced in March 2024 for the third-generation Infiniti QX80. It is also used in the related Nissan Patrol/Armada. It is a larger version of the VR30DDTT and replaces the 5.6-liter VK56 V8 engine in Nissan's largest automobiles. A bore and stroke of Template:Cvt makes for an overall displacement of Template:Cvt.

Applications:

Years	Model	Power output	Torque	Market
2024–present	Infiniti QX80 (Z63)	Template:Cvt at 5,600 rpm	Template:Cvt at 3,600 rpm	North America
2024–present	Nissan Patrol/Armada (Y63)	Template:Cvt at 5,600 rpm		Australia, Middle East, North America, Philippines

Nissan GT-R (R35) is powered by the VR38DETT

VR38DETT

Designated the VR38DETT by Nissan, the engine is used from 2007–2025 in the Nissan GT-R and the limited production Nissan Juke-R.

The VR38DETT featured 24 valves controlled by dual overhead camshafts (2 per cylinder head) with variable valve timing on the intake only. The block is cast aluminium with 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 its power cycle. 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.

Since 2011, all VR38DETTs produced came with a red top engine cover in the GT-R

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 weighed .

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
• Multi port fuel injection
• 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

Applications:

Years	Model	Power output
2007–2025	Nissan GT-R
2011	Nissan Juke-R (only 5 units were produced)
2014	[[Infiniti Q50#Q50 Eau Rouge (2014)|Infiniti Q50 Eau Rouge Prototype]] (Concept car)
2023	Praga Bohema
Racing:
2012–present	Nissan GT-R Nismo GT3
2014–2021	Renault Sport R.S. 01
2017–2019	Ligier Nissan DPi
2024–present	Nissan Fairlady Z GT300

VR38DETT NISMO Engine Tuning Menu Concept (2016)

It is a version of VR38DETT engine used in Nissan GT-R, with GT3-spec camshaft, 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.

Production

The engines are hand built by five specially trained mechanics called "Takumi Craftsmens" on a special line at Nissan's Yokohama plant and their names are badged on every GT-R engine. The cars are built at their Tochigi plant on a shared production line.
