Nissan VK engine

File:VK45DE.jpg

The {{convert|4494|cc|L CID|1|abbr=on}} VK45DE was introduced in 2002 and is built in Yokohama, Japan. Bore and stroke is {{convert|93x82.7|mm|in|abbr=on}}. Output is {{convert|340|hp|kW PS|0|abbr=on|lk=on}} at 6,400 rpm with {{convert|46|kgm|0|abbr=on|lk=on}} of torque at 4,000 rpm. Redline is at 6,600 rpm. It has an aluminum engine block and aluminum DOHC cylinder heads. It uses SFI, has 4 titanium valves per cylinder with Continuous Variable Valve Timing and features forged steel connecting rods, 4 one-piece cast camshafts, an unusual variable-flow induction system optimizes airflow for low- and high-speed operation, low-friction molybdenum-coated pistons, and a microfinished forged crankshaft.

A flat-plane crankshaft version of the VK45DE was used by Nismo for Super GT races with the Nissan GT-R instead of using the GT-R's VR38DETT twin-turbo V6 engine.{{cite web|url=http://www.autocar.co.uk/News/NewsArticle/Nissan-GT-R/230696/ |title=Autocar article about the Super GT Nissan GT-R |url-status=dead |archive-url=https://web.archive.org/web/20110927124908/http://www.autocar.co.uk/News/NewsArticle/Nissan-GT-R/230696/ |archive-date=September 27, 2011 }} The VK45DE was previously used in Nissan's 350Z Super GT car in 2007, replacing the previous VQ30DETT used in that car. In race trim, the Super GT VK45DE produces {{convert|500|PS|kW hp|0|abbr=on}} and {{convert|52|kgm|0|abbr=on}} of torque.{{cite web|url=http://www.nismo.co.jp/motorsports/race/SUPERGT2008/specifcation.html|title=NISMO Japan's Super GT GT-R spec sheet in Japanese}} The engine idles at around 3,500 rpm and is restricted to the above specified power output. Without such restrictions, the engine is reputedly capable of producing nearly {{convert|800|PS|kW hp|0|abbr=on}}.{{cite web|url=https://www.youtube.com/watch?v=yaowvWwD-Rs|title=YouTube video of NISMO engineer interview regarding the Super GT Nissan GT-R|website=YouTube }} Nismo reasons that by using the engine, they eliminate turbo lag, save weight and generally prefer the torque curve of the atmospheric V8. Also in the Super GT series, an unbranded VK45DE is used for "Mother Chassis" cars; the engine is labeled the GTA V8.{{cite web|url=https://www.racecar-engineering.com/articles/gt300-mother-chassis/3/|title=GT300 Mother Chassis|website=Race Car Engineering|first=Sam|last=Collins|access-date=19 May 2023 }}

The VK45DD is a {{convert|4494|cc|L CID|1|abbr=on}} V8 engine that is very similar to the VK45DE but adds a direct injection fuel system. This was Nissan's first V8 with direct injection (NEO-Di). It officially produces {{convert|280|PS|kW hp|0|abbr=on}} at 6,000 rpm and {{convert|46|kgm|0|abbr=on}} at 3,600 rpm, but it has unofficially over {{convert|300|PS|kW hp|0|abbr=on}}. It has a compression ratio of 11.0:1, and a bore and stroke of {{convert|93x82.7|mm|in|abbr=on}}.

The VK50VE is a {{convert|5026|cc|L CID|1|abbr=on}} V8 engine with {{convert|390|hp|0|abbr=on}} at 6,500 rpm and {{convert|51|kgm|0|abbr=on}} at 4,400 rpm and redline is set at 6,800 rpm. Bore x stroke are {{convert|95.5x87.7|mm|2|abbr=on}} and compression ratio is 10.9:1. The valvetrain is a dual overhead cam (DOHC) design with a continuously variable valve timing control system (CVTCS). The engine also features Nissan's VVEL valve timing technology.{{cite web |url=http://nissan.iconicweb.com/assets/specs/2009_FX_Specs_NNA_Final.pdf |title=Iconicweb FX Specs }}{{Dead link|date=April 2020 |bot=InternetArchiveBot |fix-attempted=yes }}

The VK56DE is a {{convert|5552|cc|L CID|1|abbr=on}} version built in Decherd, Tennessee. Bore and stroke is {{convert|98x92|mm|in|abbr=on}}. Output is {{convert|317|-|320|hp|kW PS|0|abbr=on}} at 4,900 rpm with {{convert|522|to|533|Nm|lbft|0|abbr=on}} of torque at 3,600 rpm. It has aluminum-alloy block and heads and low-friction molybdenum-coated pistons. The valvetrain is a dual overhead cam (DOHC) design with a continuously variable valve timing control system (CVTCS) on the intake valves. It also has 4 valves per cylinder with micro-finished camshafts and ductile iron cylinder liners for increased durability.

Nismo used the VK56DE for FIA GT1 racing in the Nissan GT-R GT1 from 2010 to 2011. In race trim, it produced {{convert|600|hp|0|abbr=on}} and {{convert|650|Nm|0|abbr=on}} of torque.{{cite web|url=http://www.topgear.com/uk/car-news/nissan-gtr-gt1-2009-04-08 |title=Nissan GT1 GT-R news - GT-R goes GT1 - 20090 - BBC Top Gear |publisher=Topgear.com |date=2009-04-08 |access-date=2012-01-27}}

The Nissan Motorsport VK56DE was launched in Australia for the V8 Supercars Championship in 2013 by Kelly Racing in Melbourne. The engine has been reduced in capacity to {{convert|4990|cc|L CID|1|abbr=on}} to fit the V8 Supercars regulations. It has a bore and stroke of {{convert|102.69x75.31|mm|2|abbr=on}}. It was fitted to a Nissan Altima version of the V8 Supercars "Car of the Future" specification that competed from 2013 until 2019.{{cite web |url=http://www.v8supercars.com.au/championship/newsarticle/nissan-unveils-2013-v8-supercar-engine/tabid/70/newsid/12864/default.aspx |title=Nissan Unveils 2013 V8 Supercar Engine |publisher=v8supercars.com.au |date=2012-09-04 |access-date=2012-10-28 |archive-url=https://web.archive.org/web/20121107183243/http://www.v8supercars.com.au/championship/newsarticle/nissan-unveils-2013-v8-supercar-engine/tabid/70/newsid/12864/default.aspx |archive-date=2012-11-07 |url-status=dead }}

Notes:

• The Titan, Armada, and Pathfinder power figures are for regular 87 octane fuel. The {{convert|320|hp|0|abbr=on}} Infiniti QX56 & Nissan Patrol are tuned for premium (91+ octane) fuel.
• Some VK56DE powered vehicles are E85 capable.

The VK56VD is a {{convert|5552|cc|L CID|1|abbr=on}} 32-valve, DOHC, Direct Injection Gasoline (DIG) aluminum-alloy V8 and features Nissan's latest VVEL (Variable Valve Event & Lift System). The direct injection system provides better wide-open throttle performance and improved fuel economy and emissions performance by reducing engine knock, improving combustion stability and controlling injection more precisely.
