Toyota 1FZ-FE Engine Specifications
The Toyota 1FZ-FE is a 4.5 L (4,476 cc, 273.14 cubic inches) straight-six, four-stroke cycle naturally aspirated gasoline engine. It was manufactured by the Toyota Motor Corporation from 1986 to 1992. The engine features a cast-iron block and aluminum cylinder head with dual chain-driven overhead camshafts and four valves per cylinder (24 in total). The 1FZ-FE is equipped with an electronic fuel injection system and ignition system with a mechanical distributor. In 1998 the engine was equipped with the distributorless electronic ignition system. It has a 100.0 mm (3.94 in) cylinder bore and 95.0 mm (3.74 in) piston stroke. Compression ratio rating is 9.0:1. This engine produced 215 PS (158 kW; 212 HP) at 4,600 rpm or 243 PS (179 kW; 240 HP) at 4,600 rpm of maximum horsepower and 373 Nm (38 kgm, 274.9 ft-lb) at 3,200 rpm or 407 Nm (41.5 kgm, 300 ft-lb) at 3,600 rpm of peak torque.
