Toyota FZ engine

The engine displaced 4.5 L (4,477 cc) with a bore and stroke measuring 100 mm × 95 mm (3.94 in × 3.74 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]

The 1FZ-F produced 188 hp (140 kW) at 4400 rpm and 268 lb⋅ft (363 N⋅m) at 2800 rpm; its fuel injected counterpart produced 212 hp (158 kW) at 4600 rpm and 275 lb⋅ft (373 N⋅m) at 3200 rpm.

Starting in 1998, the fuel injected version (1FZ-FE) was updated in certain non-US markets. This version of the engine received many updates over the previous version such as a redesigned head, more compact pistons, updated throttle body, an improved intake manifold with longer intake runners, 4 nozzle fuel injectors to improve fuel atomization and direct ignition (via a wasted spark set-up with three dual outlet coils); the engine pictured here is that variant discernible by the intake manifold and lack of distributor. This version of the 1FZ-FE produced 240 hp (179 kW) at 4600 rpm and 300 lb⋅ft (407 N⋅m) at 3600 rpm on 91 Octane Fuel (RON) without a catalytic converter.

Also, a de-rated LPG version was built for the 7FG/7FZ series forklifts. Called 1FZ-E it produced 63 kW (84 hp) at 2350 rpm and 294 N⋅m (217 lbf⋅ft) at 1200 rpm [3]

The 1FZ-F and -FE were used in the following vehicles:

• 1992–2009 Toyota Land Cruiser (FZJ7x)
• 1992–2007 Toyota Land Cruiser (FZJ80)
• 1998–2007 Toyota Land Cruiser (FZJ100, FZJ105)
• 1995–1997 Lexus LX 450 (1FZ-FE only)
• Toyota 5FG/5FD series forklifts[4]
• Toyota 7FG/7FD series forklifts[3]
