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.
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.
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.
