Toyota G engine
The Toyota Motor Corporation G-family engine is a family of straight-6 piston engines produced from 1979 to 2008. It is notable in that only a single displacement, 2.0 L (1,988 cc), was produced in this series. Initially belt-driven OHC non-interference engines (except the VVT-i version which is an interference engine), multivalve DOHC (except the 1G-EU SOHC 12 valve engine) and variable valve timing were added later during the production run. The 1G-GEU was Toyota's first mass produced four-valve twincam engine. A prototype version of the 1G-GEU called the LASREα–X, featuring twin-turbos, variable valve timing and intake as well as variable displacement, was fitted to the Toyota FX-1 show car at the 1983 Tokyo Motor Show. It showcased a number of technologies which were later to become commonplace. This engine was designed around the new LASRE technology for lighter weight – such as sintered hollow camshafts. These engines were used as a lower-displacement alternative to the more upmarket M family and JZ family straight-sixes.
For ten months (in 1967-1968), Toyota also offered Hino's GR100 engine as the "Toyota G" in the shortlived Briska light truck.
After Toyota's takeover of Hino Motors in 1967, the Briska one-tonne truck was sold with Toyota badging for ten months. The engine code was changed from Hino's "GR100" to "G" for these cars. The engine is a 1251 cc watercooled OHV inline-four with distant Renault origins and was originally developed by Hino for their Contessa passenger car. Bore and stroke are 71 mm × 79 mm (2.80 in × 3.11 in), maximum power 63 PS (46 kW) at 5500 rpm. Hino's earlier variants of this engine had a variety of power outputs, ranging from 52 to 65 PS.
Apart from its name, this engine is unrelated to the later series of Toyota G engines.
Since just one displacement was offered, all G-family engines are marked 1G and share the same "square" 75 mm (2.95 in) bore and stroke.
Applications:
The export-spec two-valve 1G-E had no emissions controls and were used in commercial vehicles and for a few export markets, mostly southeast Asia. Typical specifications:
The Japan-spec 1G-EU was produced from 1979 through 1988. This and the 1G-E are the only two-valve SOHC members of the family. Output was 105–125 hp (78–93 kW; 106–127 PS) at 5400 rpm and 157–172 N⋅m (116–127 lb⋅ft) at 4400 rpm.
