Designated the VR38DETT by Nissan, the engine is used from 2007–Present in the Nissan GT-R{{cite web |url=http://www2.nissan.co.jp/GT-R/R35/0710/ |title=日産：NISSAN GT-R [ GT-R ] スポーツ＆スペシャリティ/SUV Webカタログ ホーム |publisher=.nissan.co.jp |date=2007-10-24 |access-date=2010-03-26 |url-status=dead |archive-url=https://web.archive.org/web/20110928195909/http://www2.nissan.co.jp/GT-R/R35/0710/ |archive-date=2011-09-28 }} 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 {{Convert|0.15|mm|in|abbr=on}} 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.{{Cite web |url=http://jdmspecengines.com/nissan-engines/vr-series/vr38dett-engine.html |title=JDM Spec Engines - Nissan VR38DETT Engine |access-date=2013-01-29 |archive-date=2015-12-08 |archive-url=https://web.archive.org/web/20151208092407/http://jdmspecengines.com/nissan-engines/vr-series/vr38dett-engine.html |url-status=usurped }}
