Toyota G engine

The Toyota G-family engine is a family of straight-six piston engines that Toyota produced from 1979 to 2008, notable because only one displacement of 2.0 litres (1,988 cc) was built. The early engines were belt-driven OHC units with no valve interference, and multivalve DOHC heads and variable valve timing were added later in the production run. The 1G-GEU was Toyota's first mass produced four-valve twincam engine, and a prototype of it called the LASRE alpha-X, with twin turbochargers, variable valve timing and variable displacement, was fitted to the Toyota FX-1 show car at the 1983 Tokyo Motor Show. The G engines served as a lower-displacement alternative to the M and JZ six-cylinder families, in cars such as the Soarer, Crown, Mark II and the Lexus IS 200.
