The 1987–1998 4A-FE is the descendant of the carbureted 4A-F.
The two generations of this engine can be identified by the external shape of the engine. The first generation (1987–1993) featured a plate on the head which read "16 valve EFI" and fuel injectors in the head. The second generation had a higher profile cam design in the head, a cam cover with ribs throughout its length, and fuel injectors in the intake manifold runners. Mechanically, the late-model motors received MAP load sensing and redesigned pistons, intake ports, and intake manifold. The second generation engine was produced from 1992–1998 (1993–1997 in the US).

The largest production A-series engine was the 1.8 L (1762 cc) 7A-FE. Produced from 1993 to 1998, it was a 4-valve DOHC narrow-valve-angle economy engine stroked out from the 4A, also using the 4A-FE's slave-cam concept. Cylinder bore was 81 mm (3.19 in) and stroke was 85.5 mm (3.37 in).
An early Canadian version produced 115 hp (86 kW) at 5600 rpm and 110 ft·lbf (149 N·m) at 2800 rpm. The common (1993 to 1994 North American) version is rated at 115 hp (86 kW) at 5600 rpm and 115 ft·lbf (155 N·m) at 2800 rpm. The engine output was changed for the 1995 to 1997 (North American) version mainly due to a different antipollution system and different intake which made it rate at 105 hp (78 kW) at 5200 rpm and 117 ft·lbf (159 N·m) torque at 2800 rpm
In the United States, the 7A-FE's most common application was in the 1993–1997 Corolla (7th generation). The engine was also used in some 1994–1999 Celicas (6th generation) at the base ST trim level, as well as the Toyota Corolla's clone, the Geo Prizm.
The Indonesian and Russian version of the 7A-FE has the strongest output, 120 hp (89 kW) at 6000 rpm and 16 kgf·m (157 N·m) at 4400 rpm, with 9.5 compression ratio. It appears in the 8th generation Corolla (AE112).
It is a non-interference type engine.
Toyota never made a wide-valve angle 7A-GE based on the 7A, but many enthusiasts have created one using a combination of 7A-FE parts (block, crank, rods) and 4A-GE parts (head, pistons). Likewise, an unofficial supercharged "7A-GZE" could be built from 7A-FE and 4A-GZE parts.

Aww man, at least you tried. What are you planning to try next?
