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).[2]

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.[3] Still showing unmistakable Hillman origins it displaces 1,491 cc (91.0 cu in) and has 60 PS (44 kW).[2] The GL150 was fitted to the 1959 Isuzu Elf and the 1961 Bellel.

General Motors

Isuzu G engine

G130

The 1.3 L G130 OHV engine was used in the Isuzu Bellett, Bellett B, and Bellett Express. Bore x Stroke is 75 mm x 75 mm, with a displacement of 1,325 cc (80.9 cu in).

The 1.4 L G140 OHV 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.[5]

G150

Bore x Stroke: 79 mm x 75 mm, displacement: 1,471 cc (89.8 cu in)

There is also an SOHC version of this called the G161S/G161Z, which was used in the Florian, the Isuzu Gemini, Holden Gemini and Chevrolet Chevette. Later, this became renamed the 4ZA1. A further development was the twin-cam G161W engine (still with eight valves) first presented in the Isuzu Bellett GT-R in March 1968.[6]

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 & early Isuzu Piazza with 135 hp (101 kW) and 123 lb·ft (167 N·m) of torque. It was also installed in 19821985 GMC S-15 pickup trucks,[7] 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 motor shared with its J-platform compacts since it was locally produced.
