The Toyota FZ engine was a 24-valve, 4.5L DOHC straight-6 internal combustion engine manufactured by Toyota to replace the F-series engine. It was used primarily in SUVs because of its large displacement, smoothness, ruggedness and torque.
Technical data
The engine displaced 4476 cc with a bore and stroke measuring 100 millimetres (3.9 in) x 95 millimetres (3.7 in), respectively and a 9.0:1 compression ratio; the head used Toyota's narrow-angle overhead camshafts for better fuel economy.[1] The 1FZ had only two variants available: the 1FZ-F and the 1FZ-FE. The only significant difference between the two was the inclusion of electronic fuel injection on the 1FZ-FE, whereas the 1FZ-F used a carburetor.[2] Starting in 1998, the fuel injected version of the 1FZ-FE was also manufactured with a direct ignition variation available in certain non-US markets (the engine pictured here is that variant discernible by the intake manifold and lack of distributor).
The 1FZ-F produced 190 horsepower (140 kW) at 4400 RPM and 268 pound-feet (363 N·m) at 2800 RPM; its fuel injected counterpart produced 212 horsepower (158 kW) at 4600 RPM and 275 pound-feet (373 N·m) at 3200 RPM.
Usage
The 1FZ-F and -FE were used in the following vehicles:
- 1984–2009 Toyota Land Cruiser (FZJ7x)
- 1993–2006 Toyota Land Cruiser (FZJ80)
- 1998–2007 Toyota Land Cruiser (FZJ100, FZJ105)
- 1995–1997 Lexus LX 450 (1FZ-FE only)
- 02-7FG35 Toyota Counterbalance Forklift with LPG/Dual Fuel conversion
