The Toyota 1G-FE is a 2.0 L (1,988 cc, 121.3 cu·in) straight-six, natural aspirated four-stroke liquid-cooled internal combustion vertical gasoline engine, manufactured by Toyota from 1988 to 2005.
A 75.0 mm (2.95 in) cylinder bore and 75.0 mm (2.95 in) piston stroke give the 1G-FE engine a total of 1,988 cc of displacement. The compression ratio rating is from 8.0:1 to 10.5:1 depending on the engine modification.
The 1G-FE engine had three generations:
- 1-st gen: (1988-1996). This engine produced 135.0 PS (99 kW; 133.0 HP) at 5,600 rpm of maximum horsepower and 176 Nm (17.9 kg·m; 129.9 ft·lb) at 4,400 rpm of peak torque.
- 2-nd gen: (1996-1998) The engine has 140.0 PS (103 KW; 138.0 HP) at 5,600 rpm of output power and 185 Nm (18.9 kg·m; 136.5 ft·lb) at 4,400 rpm of peak torque.
- 3-rd gen: (1998-2005) This 1G-FE BEAMS version has 160 PS (118 KW; 158 HP) at 6,200 rpm of maximum horsepower and 200 Nm (20.4 kg·m; 147.6 ft·lb) at 4,400 rpm of peak torque.
