Petrol

GH engine

Isuzu's first petrol engines were license built Hillman units for the locally assembled Minx, from 1953. Called the GH10 it has a bore of and a stroke of for a displacement of . Power is . In 1955 this was updated to the GH12, a square design with a 76.2 mm bore and stroke for a displacement of . This was upgraded in 1956 for more power, rather than the original's , and was renamed GH100. In 1958, power increased yet again, to .

GL engine

For 1959 Isuzu developed their own square design () called the GL150, Isuzu's first own petrol engine. Still showing unmistakable Hillman origins it displaces and has . The GL150 was fitted to the 1959 Isuzu Elf and the 1961 Bellel.

General Motors

• The Isuzu Hombre used a General Motors-built Vortec 2200 Engine with 118 hp (86 kW) and 140 ft·lb (190 N·m) of torque.
• 2004–2006 Isuzu i-Series used a General Motors-built Vortec 2800 Engine with 175 hp (130 kW) and 185 ft·lb (251 N·m) of torque.
• 2007–2008 Isuzu i-Series use a General Motors-built Vortec 2900 Engine with 185 hp (138 kW) and 195 ft·lb (263 N·m) of torque.

Isuzu G engine

Designation	Description	Bore	Stroke	Displacement	Power Rating	Valvetrain
G130	This engine was used in the Isuzu Bellett, Bellett B, and Bellett Express.					OHV
G140	The 1.4 L G140 engine was used in the Chevrolet Chevette in North America. The engine block and associated components for the USA market Isuzu G-series engines were locally produced under license by a GM engine casting and assembly plant in Flint, Michigan. In South America an overhead-cam version was adapted, and later developed into a 1599 cc version with a 75.7 mm stroke.					OHV
G150	The 1.5 L G150 engine was used in the Isuzu Bellett and the Isuzu Elf.					OHV
G160/G161	The eight-valve 1.6 L G160/G161 engine was used in the Isuzu Florian and the Isuzu Bellett GT, as well as a number of commercial vehicles including the Elf 150 (KA41/51). The G160 has a three main bearing crankshaft, whereas the G161 has five bearings. There is also an SOHC version of this called the G161S, which was used in the Florian and the Bellett. A new version of this engine, with the same dimensions, was called the G161Z and was installed in the Florian, Isuzu Gemini, Holden Gemini and Holden Rodeo, and Chevrolet Chevette. Part of the "Z" engine family, this was later renamed the 4ZA1. A further (albeit earlier) development was the twin-cam G161W engine (still with eight valves) first presented in the Isuzu Bellett GT-R in March 1968.					OHV
G180	The 1.8 L G180SS engine was used in the Isuzu Bellett GT. The 1.8 L G180Z SOHC engine was used in the 1972–1976 Opel Kadett, Isuzu Gemini, Chevrolet LUV, and Isuzu 117 Coupé. There is also the G180W DOHC eight valve engine which was used in the Gemini ZZ (Japan only) and the Isuzu 117 Coupé.				@4800rpm @3000rpm	SOHC
G200	The 2.0 L G200Z engine was used in the 1981–1985 Chevrolet LUV and also Isuzu Trooper (Holden Jackaroo in Australia). With carburettor it has 86 hp, with EFI in the Isuzu Piazza 90 hp in the US and 110 hp in Japan. The G200W DOHC eight valve engine was found in the 19??-1985 JDM, Isuzu 117 Coupé and early Isuzu Piazza with 135 hp (101 kW) and 123 lb·ft (167 N·m) of torque. It was also installed in 1982–1985 GMC S-15 pickup trucks, where it received the LR1 engine code. Unlike the 1.4 which was locally produced, the G200 was imported. It was also used with the second generation LUV and Isuzu P'UP until GM discontinued it as the entry level powerplant when the Iron Duke was made the base motor after 1985; some early S10/S15s came with the optional GM 122 engine shared with its J-platform compacts since it was locally produced.				@4600rpm @3000rpm	SOHC
G201	This 2-liter inline-four is a gasoline-powered version of the diesel C190. It has an 8.0 : 1 compression ratio. It was fitted to certain models of the Isuzu Elf 250 (TLG42).				at 4800 rpm at 3000 rpm	SOHC

It was also used in the 1979–1981 Isuzu 117 Coupé XD/XDL, one of the first cars with sporting pretensions to be fitted with a diesel engine. In the 117, claimed max power (JIS) increased to at 4,300 rpm. It is a bored out version of the 2-litre DL201 and was first seen in the 1964 Isuzu Elf, as the C220 with 62 PS. For the 1968 new model Elf it was upgraded (now with 65 PS) and called the C221.					8 Valve OHV
C240	The C240 was often used in stationary and forklift applications. It has been used in the second and third generation Isuzu Elf 250 since late 1969 (TLD23) and also in the rare, front-wheel drive "Elf Mypack" (KUD20). For later industrial and marine applications, this engine has been called 4AB1. This family of Isuzu engines were fitted in early diesel jeepneys and CJ2A, CJ3A jeeps made by Francisco Motors and Sarao Motors in the Philippines.					8 Valve OHV

Better known as the "Circle L engine", it is made in Poland by Isuzu Motors Polska and is available in certain Opel and Honda vehicles. It was available in versions of 100, 110 and latest 130 PS. The only visible difference between the versions is the relocation of the oil filler cap from upper right (Honda 2003-2005, engine type 4EE 2, 100PS version, 5-hole injector nozzles), to lower right, then to lower left corner of the engine (Opel engine types A17DT A17DTC A17DTE). The early version used 5-hole injector nozzles, the latest has 7-hole injector nozzles for better emissions and fuel economy.					16 Valve DOHC
A17DTL A17DTN	After the ISUZU Polska factory went under full GM ownership, the engine marking changed to A17. All modifications of the original 4EE2 are physically only minor and can be considered tuning instead of an all-new development.				Template:Cvt	16 Valve DOHC
A17DTJ A17DTC A17DTE	All the A17 engines are almost identical to the 4EE2 base engine, the main changes are in the ECU, control software, camshaft position sensing wheel, added sensors (exhaust temperature), injector upgrades and modifications of the engine cover, resulting in shifting oil cap position.
