Toyota FZ engine

The Toyota FZ engine is a 24-valve, 4.5 litre (4,477 cc) DOHC straight-six internal combustion engine that Toyota built to replace the F-series engine. Its large displacement, smoothness, ruggedness and torque made it a choice mainly for sport utility vehicles. Bore and stroke are 100 mm by 95 mm with a 9.0:1 compression ratio, and the head uses Toyota narrow-angle overhead camshafts for better fuel economy. Only two variants were offered, the carburetted 1FZ-F and the fuel injected 1FZ-FE, which made 212 hp in its first form and was revised from 1998 in some markets with a redesigned head, direct ignition and more compact pistons. A de-rated LPG version, the 1FZ-E, was built for forklifts.
