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, for a British design typically long, 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).
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.
