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 65 mm (2.56 in) and a stroke of 95 mm (3.74 in) for a displacement of 1,260 cc (76.9 cu in). Power is 37.5 PS (28 kW). In 1955 this was updated to the GH12, a square design with a 76.2 mm bore and stroke for a displacement of 1,390 cc (84.8 cu in). This was upgraded in 1956 for more power, 46 PS (34 kW) rather than the original's 43 PS (32 kW), and was renamed GH100. In 1958, power increased yet again, to 50 PS (37 kW).

GL engine

For 1959 Isuzu developed their own square design (78 mm or 3.07 in) called the GL150, Isuzu's first own petrol engine. Still showing unmistakable Hillman origins it displaces 1,491 cc (91.0 cu in) and has 60 PS (44 kW). 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.

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.	82 mm (3.2 in)	66.2 mm (2.61 in)	1,398 cc (85.3 cu in)	53 PS (39 kW)	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.	82 mm (3.2 in)	75.7 mm (2.98 in)	1,599 cc (97.6 cu in)	61 PS (45 kW)	OHV

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.	87 mm (3.4 in)	82 mm (3.2 in)	1,949 cc (118.9 cu in)	82 hp (83 PS; 61 kW) @4600rpm 101 lb⋅ft (137 N⋅m) @3000rpm	SOHC

4EE2	This engine is now produced by Opel, who calls it the Ecotec DTi/CDTi. 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.	79 mm (3.1 in)	86 mm (3.4 in)	1,686 cc (102.9 cu in)	74 kW (101 PS)	16 Valve DOHC
