VR38DETT

Designated the VR38DETT by Nissan, the engine was originally developed and used from 2007–2025 in the Nissan GT-R. It is the first engine produced in Nissan's VR series, and the most powerful production engine produced by a Japanese manufacturer.

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 0.15 mm 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.

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 608 lb.

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
