4a คือ 1600cc 5a คือ 1500cc และ7a คือ 1800cc ครับ ผมเองก็ทราบแค่นั้นครับ แหะๆ
รอผู้รู้อิกทีนะครับ
อันนี้มาจากวิกิพีเดียนะครับ
4A-FE
1st generation 4A-FE engine.
2nd generation 4A-FE engine.

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).[5]
Toyota designed this engine with fuel economy in mind. The 4A-FE is basically the same as the 4A-F (introduced in the previous generation of Corollas), the most apparent difference being the electronic fuel injection system as noted by the E. The engine was succeeded by the 3ZZ-FE, a 1.6-liter engine with VVT-i technology.
* Engine displacement: 1.6 liters (1587 cc)
* Layout: DOHC Inline-4 (Straight-4)
* Valves: 16, 4 for each cylinder
* Power: 105 hp (78 kW) @ 5800 rpm
(Europe/Japan spec: 115 PS (85 kW; 113 hp) @ 6000 rpm)
* Torque: 101 ft·lbf (137 N·m) @ 4800 rpm
* Redline: 6300 rpm
* Fuel Delivery System: MPFI
Note: power and torque specs are from the 1988–1992 North American Corollas.
The 4A-FE is different from the 4A-GE in terms of performance and power. Although both have the same displacement and are DOHC, they were optimized for different uses. The first obvious difference are the valves, the engine's intake and exhaust valves were placed 22.3° apart (compared to 50° in the G-Engines). The second is that it employed a "slave cam system", the camshafts being geared together and driven off one camshaft's sprocket (both camshafts' sprockets on the G-Engine are rotated by the timing belt). Some of the less directly visible differences were poorly shaped ports in the earlier versions, a slow burning combustion chamber with heavily shrouded valves, less aggressive camshaft profiles, ports of a small cross sectional area, a very restrictive intake manifold with long runners joined to a small displacement plenum and other changes. Even though the valve angle is closer to what is considered in some racing circles to be ideal for power (approximately 25 degrees), its other design differences and the intake which is tuned for a primary harmonic resonance at low RPM means that it has about 10% less power compared to the 4A-GE engine. This engine design improves fuel efficiency and torque, but compromises power. Power rating varied from 100–105 hp in the US market. Late-model engines are rumored to make slightly greater power but still received a 105 hp rating.
Although not as powerful as the 4A-GE, both engines are renowned for the power they produce from such a low displacement relative to other engines. Toyota engineers had skillfully optimized the power and torque from the company's relatively low-displacement engines.
5A-FE
Toyota joint venture partner Tianjin FAW Xiali now produces the 5A-FE (dubbed 5A+) for its Vela and Weizhi (C1) subcompact sedans.
Output for the 1987 FI version was 104 hp (78 kW) at 6000 rpm and 97 ft·lbf (131 N·m) at 4800 rpm. The later one produced 100 hp (75 kW) at 5600 rpm and 102 ft·lbf (138 N·m) @ 4400 rpm. The version now produced by Xiali produces 100 hp (75 kW) at 6000 rpm and 96 ft·lbf (130 N·m) @ 4400 rpm.

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.
