3E

The 3E is a 1.5 L (1456 cc) SOHC version. Output ranged from 78 hp (58 kW) to 87 hp (65 kW) at 6000 rpm with 87 ft·lbf (118 N·m) of torque at 4000 rpm to 89 ft·lbf (121 N·m) of torque at 4800 rpm. It appeared in 1986, and was discontinued after 1994. The 3E engines appeared in both carbureted and fuel-injected applications. The 3E-TE, appearing in 1986, was a turbocharged engine producing 113 hp (84 kW) at 5600 rpm with 127 ft·lbf (172 N·m) of torque at 3200 rpm.

Applications:

* Toyota Tercel
* Toyota Corolla II
* Toyota Starlet(EP71)

The ’3E’ and ’3E-E’ engines are considered slightly less reliable than other Toyota engines, although they are also among the easiest engines to service. The most common problems affecting these engines are premature valve stem seal (nitrile) failure, carbon buildup on the intake valves, and collapse of the oil control ring on the piston. Any of these conditions can lead to rough idling, stalling, and fouled spark plugs, and therefore need to be differentially diagnosed. The valve stem seals, at least, can be replaced with silicone or viton-based seals which last much longer.

4E

The 4E is a 1.3 L (1331 cc) DOHC version. Bore was 74 mm and stroke 77.4 mm. Output ranged from 81 hp (60 kW) at 6400 rpm to 99 hp (74 kW) at 6600 rpm with 81 ft·lbf (110 N·m) of torque at 3600 rpm to 6 ft·lbf (8.1 N·m) of torque at 5200 rpm. It appeared in 1989, and was discontinued after 1998. The 4E engines appeared in fuel-injected applications

Applications:

* Toyota Starlet EP81, EP82, EP85, EP91, EP95
* Toyota Tercel

1st Gen 4E-FE

The first generation of 4E engines found in the Starlet GI, Soleil and Corolla models were produced from 1989 until 1996. The engine found in these two models produced 99 bhp (74 kW) @ 6600 rpm and 86 ft·lbf (117 N·m) @ 5200 rpm. this engine had more in common with the 4E-FTE, sharing the same throttle body, and slightly larger fuel injectors.

* Specs:
* 74 mm Bore
* 77.4 mm Stroke
* 9.6:1 Compression Ratio

The 2nd Generation of the 4E-FE was introduced in 1996 producing less peak power: 88 bhp (66 kW) @ 5500 rpm, but with a slight increase in peak torque 87 ft·lbf (118 N·m) at 4400 rpm. The 2nd generation of the 4E-FE was essentially the same engine as the first but the intake and exhaust manifolds were changed along with a slight alteration of the ECU to reduce exhaust emissions.

* Specs:
* 74.3 mm Bore
* 77.4 mm Stroke
* 9.6:1 Compression Ratio

The 3rd gen in 1997 the intake manifold was changed again along with the ECU and the result was 85bhp for the Corolla and 82bhp for the Starlet. This engine was discontinued in 1999.

4E-FTE
The 1st generation 4E-FE was the basis of the 4E-FTE, appearing in 1989, which was a turbocharged engine producing 135 hp (101 kW) at 6400 rpm with 116 ft·lbf (157 N·m) of torque at 4800 rpm. The 4E-FTE was the most powerful of the E series engines ever produced. It was produced exclusively for the Toyota Starlet GT Turbo (Japan Only) and its replacement, the Toyota Glanza V (Japan only). However the 4E-FTE was a very popular conversion engine by enthusiasts for many small Toyota cars such as the Corolla, Tercel and Paseo, which it fitted into with standard Toyota parts. The 4E-FTE differed internally from the 4E-FE only by its stronger connecting rods, lower compression pistons and different head gasket. It also features a harmonic damper instead of a normal crankshaft pulley. The turbocharger fitted to the 4E-FTE was Toyota’s own CT9 model which featured an internal waste gate and had 2 modes; low (0.4 bar/40 kPa) and high (0.65 bar/65 kPa) boost. The low boost mode was electronically controlled by a solenoid valve and the ECU and the overall or high boost was controlled by the actuator connected to the turbocharger. The 4E-FTE also had a “Top mounted”, air cooled, Intercooler. The 4E-FTE was mated to the Toyota C52 transmission (EP82 Starlet GT) and the C56 transmission (EP91 Glanza V). Although aftermarket parts could substantially increase the power output of the engine, the major limitation is the fuel injection system.

* Specs:
* 74 mm Bore
* 77.4 mm Stroke
* 8.2:1 Compression Ratio

5E

The 5E is a 1.5 L (1497 cc) DOHC version. Output ranged from 94 hp (70 kW) at 5400 rpm to 110 hp (82 kW) at 6400 rpm with 91 ft·lbf (123 N·m) of torque at 3200 rpm to 100 ft·lbf (140 N·m) of torque at 4000 rpm. It appeared in 1991, and was discontinued after 1998. All 5E engines were fuel-injected.

Applications:

* Toyota Paseo
* Toyota Sera
* Toyota Tercel
* Toyota Raum
