The 4G11 displaces 1.2 L (1244 cc).
The 4G12 displaces 1.4 L (1410 cc).
The 4G13 displaces 1.3 L (1298 cc). It is an SOHC engine.
Mitsubishi Space Star
The SOHC 4G15 displaces 1.5 L (1468 cc).
Mitsubishi Lancer/Eagle Summit
The 4G16 displaces 1.2 L (1198 cc).
The Mitsubishi Astron is series of straight-4 internal combustion engines, along with Orion, Sirius, and Saturn. Engine displacement ranges up to 2.6 litre (one of the largest four cylinder engines of its time. It powered models such as the Mitsubishi Pajero, Mitsubishi Sigma and Mitsubishi Magna.
It employs a hemispherical head, chain driven single overhead camshaft (SOHC) and has 8 valves (two per cylinder). In 2.6 L (4G54) Astron II EFI guise (used in the TN Magna) it produced 93 kW at 4800 revolutions per minute and 205 N·m at a low 2300 rpm. United States passenger car versions had a small secondary intake valve, called by Mitsubishi the "Jet Valve", to induce swirl in the intake charge, enabling the use of leaner fuel/air mixtures for lower emissions. Rather than redesign the head as three valves per cylinder, the Jet Valve was designed as a cartridge containing the valve spring and seat which simply screwed into a threaded hole in the head, similarly to a spark plug but inside the cam cover, thereby reducing modifications to the head design to simply providing the threaded hole. The rocker arms for the intake valve were widened on the valve end to accommodate the extra valve, which was equipped with a very soft valve spring so as not to increase wear on the camshaft intake lobe.
In 1975, the Astron featured a modern balance shaft system, dubbed "Silent Shaft". The 2.6 was praised for its smoothness and strong low-end torque, but later in its life its power and (never great) economy was eclipsed by newer (many of them DOHC) engines.
The 4G52 displaces 2.0 L (1995 cc).
1979-1989 Dodge Ram 50
The SOHC 8-valve 4G54 displaces 2.6 L (2555 cc). It was designed for longitudinal use in rear wheel drive and all wheel drive vehicles. It was equipped with a Hitachi 2 barrel carburetor with vacuum operated progressive secondary, except for the turbocharged version and a version used in Australian Mitsubishi Magnas which were fuel injected.

The 4G55 displaces 2.3 L (2346 cc).
The 4G32 displaces 1.6 L (1597 cc). It is an 8-valve SOHC design with an aluminum head and iron block. The engine has five main bearings, a cross flow head and a single up draught carburetor. Firing order is 1-3-4-2.
Bore x Stroke: 76.9 x 86 mm (3.03" x 3.39")
The 4G33 displaces 1.4 L (1439 cc).
The 4G36 displaces 1.2 L (1238 cc).
The 8-valve SOHC 4G37 displaces 1.8 L (1755 cc).
The 4G61 normally displaces 1.6 L, but there are two distinct variations: An earlier version uses 3.03x3.39 in bore and stroke, while a later one has moved to 3.24x2.95 in. This engine was always DOHC 16-valve and used either ECFI or MPFI fuel injection. A turbocharged version was also produced for the Mirage. The 4G61 does not have balance shafts like the other 4G6x motors. Instead, it has different components, some of which can be used on the "Silent Shaft" motors.

The larger 1.8 L 4G62 was an SOHC 8-valve unit for longitudinal RWD/4WD use. With a 3.17x3.46 in bore and stroke, it displaces 1795 cc.
1988 Mitsubishi Cordia
1988 Mitsubishi Tredia
The 4G63 was a 2.0 L (1997 cc) version. Again, there were two different bore and stroke versions, and both SOHC and DOHC were produced. It is found in various Mitsubishi models including the Eclipse and Galant but also appears in Chrysler-branded versions of the Eclipse: the Eagle Talon and Plymouth Laser.It comes with either 4/6/& 7-bolt mains. The increase in main-bolts, is to reduced 'cam-crawl';the 7-bolt is used in the VR-4 & Evolution. This makes for swaps into other vehicles difficult, except the Galant GSX*.
Note that the 4G63 block in the Eclipse and Galant (and other Mitsubishi and Chrysler passenger cars) is not identical to the 4G63 block found in the Mitsubishi Mighty Max and Dodge Ram 50. The car-bound 4G63 has a bore and stroke of 3.35 in (85 mm) and 3.46 in (88 mm), whereas the truck 4G63 has a bore and stroke of 3.31 in (84 mm) and 3.54 in (90 mm).
Output for the US-spec 2004 Mitsubishi Lancer Evolution is 271 hp (202 kW) at 6500 RPM with 273 ft.lbf (370 Nm) of torque at 3500 RPM. It has a cast iron engine block and aluminum DOHC cylinder heads. It uses MPI multi-point fuel injection, has 4 valves per cylinder, is turbocharged and intercooled and features forged steel connecting rods.
In the United Kingdom, a special Lancer Evolution, the FQ-400, produces 302.13 kW (405.2 hp), from a 4G63 engine. At 202.9 hp (151.3 kW) per liter, it has possibly the highest specific output per liter of any production engine.
Its turbocharged variant, 4G63T (also sometimes referred to simply as the 4G63), has powered Mitsubishi vehicles in World Rally Championships for years in the Galant VR-4, Lancer Evolution, Carisma GT and Lancer WRC04. It was the powerplant of the Lancer Evolution when Tommi Mäkinen won his four sequential WRC championships. The engine is also used in a variety of turbocharged 2-liter models of Galant and Eclipse.

The longitudinal 4G64 was the largest variant, at 2.4 L (2350 cc). Early models were 8-valve SOHC, but a later 16-valve DOHC version was also produced. All used MPFI with a 3.41 in (86.5 mm) bore and 3.94 in (100 mm) stroke.
A later 4G64, built in Shiga, Japan, was used as recently as 2004 in transverse applications. It has an cast iron engine block and aluminum SOHC cylinder heads. It uses SFI fuel injection, has 4 valves per cylinder with roller followers and features a one-piece cast camshaft cast and aluminum intake manifold.
The version used in the Chrysler Sebring/Stratus coupes produced 147 hp (110 kW) at 5500 RPM with 158 ft.lbf (214 Nm) of torque at 4000 RPM. The Chrysler version features fracture-split forged powder metal connecting rods.
The Lancer Ralliart/Eclipse version uses forged steel connecting rods. Output is 162 hp (121 kW) at 5500 RPM with 162 ft.lbf (260 Nm) of torque at 4000 RPM.

The 6A1x series is a V6 piston engine from Mitsubishi Motors. The 1.6 L 6A10 holds the distinction of being the smallest modern production V6.
With the engine capacity of only 1.6 L (1597 cc), this is the smallest yet most powerful 1.6 L engine available on production car. With the configuration of 6 cylinders, dual overhead cam (DOHC), and 4 valves per cylinder, the 6A10 engine manages to output 140 hp (104 kW) @ 7000 rpm in stock condition.
Available in the Mitsubishi Lancer MX in 1992, this engine was once the most sought after engine for modification in Japan. In 1994, the Kotsumi's brothers from Kanagawa, Japan, managed to turn the 1.6 litre engine into a 'little monster' able to produce 430 bhp (320 kW) @ 6000 rpm without a forced induction system.

The 2.0 L (1997 cc) 6A12 is less notable than its little brother. It was available with and without the MIVEC variable valve timing system and was a DOHC 24-valve engine.
Development continued with the 2.5 L (2498 cc) 6A13.
The 6G7x series is a V6 piston engine from Mitsubishi Motors. Three displacement variants have been produced with both SOHC and DOHC. MIVEC variable valve timing was also fitted. Modern versions feature a one-piece cast crankshaft and cast aluminum intake manifold.
The 6G72 is a 3.0 L (2972 cc) engine. Bore is 91.1 mm and stroke is 76 mm. SOHC 12-valve, SOHC 24-valve, and DOHC 24-valve versions have been produced.
The latest version is used in the Eclipse and Galant. Output in 2004 is 210 hp (157 kW) at 5500 RPM with 205 ft·lbf (278 N·m) of torque at 4000 RPM. It has an cast iron engine block and aluminum SOHC cylinder heads. It uses MFI fuel injection, has 4 valves per cylinder with roller followers and features fracture-split forged steel connecting rods.

It uses MFI fuel injection, has 4 valves per cylinder and features forged steel connecting rods.
The Mitsubishi Galant was launched in 1969 as a two- and four-door sedan, sold in some markets as the Colt Galant. It featured a choice of 1·3 or 1·5 L four-cylinder engines. It was sold in the United States as the Dodge Colt from 1971.
From 1970, a fastback coupé model, the Hardtop, was added. It was the first Japanese production passenger car without side pillars. The same year saw the release of the most powerful first-generation model, the GTO, with a 1·6 L, 125 PS engine.
The second-generation Galant—in sedan and GTO forms—was more widely exported and was sold in Australia as the Chrysler Valiant Galant and in Europe as the Colt Galant. This model was more curvaceous, influenced by coke-bottle styling, and featured a larger, 1850 cmł engine, as well as a new 2·0 'Astron' unit developing 125 PS. It was also offered as the Dodge Colt in the US.
The third-generation Galant, dating from 1976, was divided into two models: the Galant Sigma (for the sedan and wagon) and the Galant Lambda (the coupé). The former was sold in many markets as the Mitsubishi Galant (without the word 'Sigma') and in Australia as the Chrysler Sigma (until 1980, after which it became the Mitsubishi Sigma). Strangely, in New Zealand it was badged as 'Galant Sigma' but colloquially referred to as the 'Sigma', a name it formally adopted after 1980.
The coupé was sold in Europe as the Mitsubishi Sapporo, in Australia as the Chrysler (and later Mitsubishi) Sigma Scorpion, and in the United States as the Plymouth Sapporo and Dodge Challenger from 1978 to 1983. On the Japanese home market, the car was known as the Mitsubishi Lambda. Initially available with Mitsubishi's Astron 2.0L 4cyl, the larger 2.6 4cyl was made a later option. 4 wheel disc brakes were standard.
A substantial facelift took place in 1980, though the rear end of the wagon was retained. Mitsubishi officially considers this a new generation Galant. It was Car of the Year in New Zealand in 1981. Production of the wagon model continued in Australia till 1987, when the Magna wagon came on stream.
From 1982 to 1983, some of the Australian Sigmas were exported to the United Kingdom with the Lonsdale badge, circumventing the voluntary 11 per cent market restriction adopted by Japanese manufacturers. The car was unsuccessful. For its final year, 1983 to 1984, it carried Mitsubishi Sigma badges in the UK before meeting its demise.
A long-lived fifth-generation model shifted to front-wheel drive for the 1984 model year as a four-door sedan. This formed the basis of the widened Mitsubishi Magna in Australia for 1985, the same year in which Mitsubishi won the Golden Steering Wheel in Germany for the Galant and Wheels’ Car of the Year for the Magna. In 1988, the standard Galant was re-released in the New Zealand market as the V3000 with a 3·0 L V6 engine and continued alongside the sixth-generation Galant for many years.
In 1987, the same platform was used for a sixth-generation model which adopted taller, rounded styling. This generation won Japanese Car of the Year in 1987 and the GS model became Motor Trend Import Car of the Year in 1989.
The Sigma designation disappeared but a new hardtop liftback model was added in 1988, called the Galant Eterna.
This generation was also sold in Canada as Dodge 2000GTX and Eagle 2000GTX.
The four-wheel-drive, four-wheel-steer 1988 Galant VR-4 (E39A) was a respected competitor in the World Rally Championship and the engine from this amazing car, the 4G63 engine was carried over to the Mitsubishi Lancer Evolution series of winning rally cars. The current VR-4 model still retains the 4WD layout and high-revving engine and is considered by many to be a serious sports sedan.
1992 Mitsubishi Galant A new-model Galant débuted in 1992, available as a four-door sedan and five-door liftback (Eterna). A Japan-only hardtop model, the Emeraude, was launched in 1992, too.
1998 Mitsubishi GalantThe eighth-generation 1996 model continued the 1992 design themes but a station wagon (known in Japan as the Legnum) was added. The liftback was deleted. This model won the 1996–7 Japanese Car of the Year award. Despite it being superseded in the US from 2003, it remains on sale in numerous countries, including Japan itself as of May 2005. This arguably makes it one of the longest-running passenger cars currently on sale in Japan, with the exception of luxury models such as the Toyota Century. The Legnum wagon (which has recently ceased production) was a popular car with tuners. Cool car!!
The United States has had the sedan-only ninth-generation PS platform model since 2003, announced at the New York International Auto Show in April of that year, for the 2004 model year. Other markets did not see it till much later. One of the first markets outside North America to get it was the Republic of China, which launched the Galant Grunder in December 2004.
It became apparent that the non-American Galants will get a front end that resembles that of the Lancer and Diamante. The new front end was designed by its former design chief Olivier Boulay. It is equipped with a 2·4 L engine producing 162 bhp.
The Middle East and eastern Europe will likely source its Galants from the United States from 2006.
In Australia, starting in the 2006 model year, Mitsubishi will be selling a highly modified larger version of the North American Galant as the 380. The 380 is a successor to the Magna and the Verada large cars that also formed the basis for the North American Diamante. The 380 is a crucial car for Mitsubishi because this is the car that will determine the future of Mitsubishi's Australian manufacturing operations.
United States production
1996 Mitsubishi Galant ES (7th-Generation US Model)In the United States, the Galant, along with the Mitsubishi Eclipse and the Eagle Talon and Plymouth Laser (the later two now discontinued), was one of the vehicles built by Diamond Star Motors, a joint venture between Chrysler (now DaimlerChrysler) and Mitsubishi, in Normal, Illinois. The plant has been wholly-owned by Mitsubishi since 1991.
The seventh-generation Galant's production was shifted to Normal, Illinois. The very first seventh-generation US-made 1994 Galant rolled off the assembly line on May 24, 1993. The eighth generation went into production there on July 7, 1998. The 2004 Galant began production on October 15, 2003.
Due to excess capacity at the plant, Mitsubishi will export Galants in 2006 to markets in the Middle East and eastern Europe. There had been a layoff at the plant in late 2004, and Mitsubishi hopes to utilize its capacity and rehire its former employees as soon as possible.
MIVEC (Mitsubishi Innovative Valve-timing-and-lift Electronic Control) is an automobile variable valve timing technology developed by Mitsubishi. MIVEC varies the lift of valves by using two different camshaft profiles. It is similar to Honda's VTEC system.
Hope above listings are informational and useful to you guys and find various source where Mitsubishi has been a platform in producing engines and parts swappable between some other manufacturers.
