The Toyota 7M-GE is a 3.0 L (2,954 cc, 180.26 cubic inches)
straight-six, four-stroke cycle naturally aspirated gasoline engine from
the Toyota M-family. The engine was manufactured by the Toyota Motor
Corporation from 1986 to 1992.
The engine features a cast-iron block, aluminum cylinder
head with dual belt-driven overhead camshafts and four valves per
cylinder (24 in total). The Toyota 7MGE is equipped with an electronic fuel
injection system. It has an 83.0 mm (3.27 in) cylinder bore and 91.0 mm
(3.58 in) piston stroke. Compression ratio rating is 9.1:1.
This engine produced from 193 PS (142 kW; 190 HP) at 6,000 rpm to 207 PS
(152 kW; 204 HP) at 6,000 rpm of horsepower and from 250 Nm (25.5 kgm,
184.3 ft-lb) at 4,800 rpm to 265 Nm (27 kgm, 195.3 ft-lb) at 4,800 rpm
