A bore and stroke of 86 mm × 100.2 mm (3.39 in × 3.94 in) makes for an overall displacement of 3.5 L (3,492 cc; 213.1 cu in).[9]

VR38DETT

Designated the VR38DETT by Nissan, the engine is used from 2007–Present in the Nissan GT-R[10] 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 0.15 mm (0.0059 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 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.[11]

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 608 lb (276 kg).[12]
