Nissan's and Japan's first mass-produced V6, the iron block/aluminum head 60° VG engine was produced in displacements between 2.0 and 3.3 liters. Early versions used SOHC cylinder heads with two valves per cylinder; later models featured DOHC cylinder heads, four valves per cylinder, a slightly different engine block and N-VCT, Nissan's own version of variable valve timing, delivering a smoother idle and more torque at low to medium engine speeds.
Nissan engineers wanted the VG to have improved performance, fuel economy, reliability, and refinement, while being both lighter and more compact than its predecessor. The resulting engine was designed by Nissan from scratch, and shared few mechanical components with its predecessor, or with any other automaker.
Extensive computer design techniques were used during development, which made the VG series one of the most advanced and high-tech engines of its day. It featured a sequential multi-port fuel injection system, and Nissan's Electronic Concentrated Control System (ECCS).
ECCS used a microprocessor and an oxygen sensor to control fuel delivery, spark timing, exhaust gas recirculation rate, and engine idle speed, depending on the current operating conditions of the engine. This system reduced carbon emissions, improved fuel economy, and improved engine performance during cold-start and warm-up conditions.
The advantages of the VG engine over its inline 6 predecessor was that its V6 configuration would have greater torsional rigidity for higher performance potential, and its shorter length would give Nissan designers and engineers more freedom for vehicle design, allowing for both more frontal crush zone space and transverse mounting for front-wheel-drive vehicles.
All VG engines use a timing belt to synchronize the camshafts with the crankshaft rather than a timing chain. The VG series engine was put into thousands of Nissan vehicles, debuting in Japan in the 1983 Nissan Gloria/Nissan Cedric, and in the US and other markets in the 1984 Nissan 300ZX.
When the Nissan VQ engine was introduced in 1994, the VG engine was slowly phased out in Nissan cars, and after 2002 it was only available in the Nissan Frontier and Nissan Xterra. The VG engine was retired in 2004, by which time all V6-powered Nissans had switched to the VQ.
The VG20E is a 1,998cc (2.0L)SOHC engine produced from 1984 on. It produces between 115PS (85kW; 113hp) and 125PS (92kW; 123hp) net. In the earlier gross rating system, early eighties' models claim 130PS (96kW; 128hp).
The VG20ET was based on the VG20E, but with an added an Variable-geometry turbocharger. The VG20ET produces 170hp (127kW). This SOHC motor debuted at the same time as the VG20E. Also coming with the Y30, this motor was known as the "Jet Turbo", and came with the Nissan Leopard models XS, and XS-II Grand Selection. Contrary to the VG30ET that came out in the US, the VG20ET came with an intercooler in certain models to push the horsepower output to 155PS (114kW; 153hp), a great jump from the normally aspirated VG20E. The turbo included with the VG20ET had two different settings. At low speeds, the turbo's wastegate would stay closed improving the response at low rpm. At high speeds, the flap would stay open, decreasing resistance and increasing exhaust flow. At its maximum flow, the flap would open at an angle of 27degrees, while the A/R ranged from 0.21–0.77. Being that the VG20ET had a short stroke 78mm ×69.7mm (3.07in ×2.74in), it was thought to have insufficient low end torque. Nevertheless, the VG20ET was a great improvement over the VG20E.
The VG20DET is an DOHC1,998cc (2.0L) engine with a ceramic turbocharger and intercooler. It has a bore and a stroke of 78mm ×69.7mm (3.07in ×2.74in) and produces 210PS (154kW; 207hp). This engine features NVTCS (Nissan's Valve Timing Control System).
The VG20P is the Autogas (Liquified petroleum gas) version of the VG20. It produces 99PS (73kW; 98hp) at 5,600rpm and 149N⋅m (110lb⋅ft) at 2,400rpm. Later versions (2004–2005) produce 105PS (77kW; 104hp) at 6,000rpm and 152N⋅m (112lb⋅ft) at 2,400rpm. It is an overhead cam, twelve-valve engine.
The VG30S is a 2,960cc (3.0L) SOHC twelve-valve engine with an electronic carburettor which produces 148PS (109kW; 146hp) at 4,800rpm and 234N⋅m (173lb⋅ft) at 3,600rpm. This engine was mainly offered in export markets with more lenient environmental regulations, such as the Middle East and Africa.
The VG30i is a 2,960cc (3.0L) engine produced from 1986 through 1989. It features a throttle body fuel injection system. It has a long crank snout, a cylinder head temperature sensor positioned behind the timing belt cover, and a knock sensor in the cylinder valley (on California models only). It produces 140PS (103kW; 138hp) at 4,800rpm and 226N⋅m (167lb⋅ft) at 2,800rpm.
The 2,960cc (3.0L)VG30E produced 153hp (114kW) and 182lb⋅ft (247N⋅m). Bore and stroke is 87mm ×83mm (3.43in ×3.27in). In the 300ZX, it produced 160hp (119kW) and 173lb⋅ft (235N⋅m) of torque. In April 1987 the "W" series VG30 was released, adding 5 horsepower but leaving torque unchanged. In 1989, the Maxima received the 160hp (119kW) rating, but also used a variable intake plenum improving torque to 182lb⋅ft (247N⋅m) at 3200 rpm.

The 2,960cc (3.0L)VG30ET was available in early production with a single Garrett T3 Variable-geometry turbocharger at 6.8psi (0.47bar) and a 7.8:1 compression ratio. The USDM and JDM version produced 200PS (147kW; 197hp) and 227lb⋅ft (308N⋅m). European versions produced 230hp (233PS; 172kW) and 252lb⋅ft (342N⋅m). When "W"-Series VG30 was released in April 1987, horsepower was increased to 205PS (151kW; 202hp). All 1987 models featured a T3 turbocharger at 6.8psi (0.47bar). In 1988 the compression ratio was changed to 8.3:1 and turbocharged with a single Garrett T25 turbocharger at 4.5psi (0.31bar) to reduce turbo lag.
The engine specified as the VG30ET engine in the Nissan GTP ZX-Turbo Racecar, was a heavily modified VG30ET producing over 551kW (749PS; 739hp) at 8,000 rpm, and over 686N⋅m (506lb⋅ft) at 5,500 rpm.[1]
The first DOHC 24 valve VG30DE engine was developed for the 1985 MID4 concept. The 2,960cc (3.0L)VG30DE produces 190 to 222hp (142 to 166kW) and 198lb⋅ft (268N⋅m). Bore and stroke is 87mm ×83mm (3.43in ×3.27in). Original Japanese market units claimed 185PS (136kW).[2] There are two versions of the VG30DE. The first was introduced in 1986 on the Japanese 300ZR (Z31) and Nissan Leopard F31, and were never sold in North America. The VG30DE has two throttle bodies facing the front of the vehicle (Nissan 300ZX and Fairlady Z) or two throttle bodies to the left (sedans and 300ZR). It was also installed with N-VCT, an early form of variable valve timing.
Early VG30DEs used large oval intake ports, and round exhaust ports, though the flange was similar to the SOHC VG engine, bolt spacing was slightly different. Late VG30DE's used slightly smaller oval intake ports, and oval exhaust ports. The bolt spacing was shared with the round-port variant from earlier years.
The VG30DET is a 3.0L (2,960cc), 24-valve, DOHC, VTC-equipped engine equipped with a T3 (Nissan N1 Type) 4-bolt Garrett Turbo running between 7.5 and 11.5psi (0.52 and 0.79bar). Generating up to 255PS (188kW; 252hp) and measuring 236lb⋅ft (320N⋅m) depending on the production year and application.
While this engine is similar to the VG30DE, it used different heads and inlet manifold. Contrary to popular belief, it was not available in the Nissan 300ZR model - the 300ZR only had an early version of the VG30DE (non turbo). The engine was available in the Cedric, Gloria, Cima and Leopard chassis.[3] It is a single-turbo engine that was used from 1987 through 1995 in the Japanese market, and the predecessor for the VG30DETT engine.
Autech Zagato Stelvio (based on the F31 Leopard) used a modified version with 280PS @ 6000rpm.

The E-series was a line of inline four-cylinder automobile engines designed and built by Honda for use in their cars in the 1970s and 1980s. These engines were notable for the use of CVCC technology, introduced in the ED1 engine in the 1975 Civic, which met 1970s emissions standards without using a catalytic converter.
The Toyota VZ engine family is a series of V6 gasoline piston engines ranging from 2.0 to 3.4 L in displacement and both SOHC and DOHC configurations. It was Toyota's first V6 engine, being made as a response to Nissan’s VG engine, one of Japan’s first mass-produced V6 engines.
The Nissan E series name was used on two types of automobile engines. The first was an OHV line used in the late 1950s and throughout the 1960s. The second was an OHC version ranging from 1.0 to 1.6 litres and was produced from 1981 till 1988. It was replaced by the GA engine series.
The Nissan H series of automobile engines is an evolution of the Nissan "R" engine which was based on the 1.5-liter, three-main bearing "G" engine used in the 1960s. Both inline-four and inline-six versions were produced. It is a pushrod OHV design with iron block, early models with an iron head, later models with aluminum head. Versions of this motor have been used in many Nissan autos and forklifts, well into the eighties and a version called H20II was in production until 2003. The SD diesels are based on this series of motors
The Nissan L series of automobile engines was produced from 1966 through 1986 in both inline-four and inline-six configurations ranging from 1.3 L to 2.8 L. It is a two-valves per cylinder SOHC non-crossflow engine, with an iron block and an aluminium head. It was the engine of the Datsun 510, Datsun 240Z sports car, and the Nissan Maxima. These engines are known for their reliability, durability, and parts interchangeability.
The Renault-Nissan MR engine family consists of straight-four 16-valve all-aluminium and water cooled automobile engines with variable valve timing co-developed by Renault and Nissan. Renault calls it the M engine. Other noteworthy features of this engine family include acoustically equal runner lengths and a tumble control valve for the intake manifold, a "silent" timing chain, mirror finished crankshaft and camshaft journals, and offset cylinder placement in an attempt for increased efficiency.
The L-series is a compact inline-four engine created by Honda, introduced in 2001 with the Honda Fit.

They can also be found in the Japanese-only Airwave wagon and Mobilio MPV.
The Nissan Leopard is a line of sport/luxury cars built by Japanese carmaker Nissan. The Leopard began life in 1980 and was discontinued in 1999. The Leopard were initially based on the Japanese market Nissan Skyline and Nissan Laurel, then later based on the chassis of their Nissan Cedric and Nissan Gloria contemporaries and were rear wheel drive. Final versions were the contributing factors to Nissan's Infiniti M and J products.
The MA is a straight-4 SOHC 0.9 L, 1.0 L, or 1.2 L engine first introduced in 1982 by Nissan, intended primarily for the K10 series Micra/March model. It shares design similarities with the older E engine, with an 8-valve hemispherical cylinder head but differs in that it uses an aluminium cylinder block. Unusually, the specified ignition timing for the MA10 running on the specified 90 RON gasoline was 2 degrees after top dead centre, reflecting a very high flame speed in the compact combustion chambers.
The Renault DiET engine also known as "D engine" or "D-Type" is a straight-4 automobile petrol engine from Renault designed to replace the existing Cléon-Fonte engine in the Renault Twingo.
The Nissan NA family of straight-four engines is a series of engines manufactured by Nissan. It is the replacement of the Z series, on which its design is based, and is mostly used in commercial vehicles due to its use of Liquefied petroleum gas for fuel on engines with a "P" suffix code.
