4A-GE, 4A-FE, or 4E-FTE
The Toyota E engine family is a straight-four piston engine series, and uses timing belts rather than chains. The E engines were the first multi-valve engines from Toyota designed with economy, practicality and everyday use in mind rather than performance.
Like many other Toyota engines from the era, the E engine series features a cast iron block , along with an aluminium cylinder head. E engines are lighter compared to earlier Toyota engines, due the hollow crankshaft , thinned casting of the cylinder block, and several other reductions in auxiliaries as well as in the engine itself.

Carbureted versions include a newly designed, variable-venturi carburetor. All of these changes improved economy and emissions. The E family supplanted the K engines in most applications.
A large number of parts in the E engine series are interchangeable between each other. Bore and stroke is Compression ratio is 9.
It appeared in It appeared in , and was discontinued after The 2E engines appeared in both carbureted and fuel-injected versions.
The 3E engines appeared in both carbureted 3E and fuel-injected 3E-E applications.
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 rubber 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.
The 4E engines appeared in fuel-injected applications. The first generation of 4E engines found in the Starlet GI, Soleil and Corolla models were produced from until This engine has more in common with the 4E-FTE, sharing the same throttle body, and slightly larger fuel injectors. However the 4E-FTE was a very popular conversion engine by enthusiasts for many small Toyota cars such as the Corolla, Tercel, Paseo and Sera which it fit into with standard Toyota parts.
The cylinder head and valve train are identical to the 4E-FE. The 4E-FTE also features a harmonic damper instead of a normal crankshaft pulley.
The Toyota E Series Engine
The low boost mode is electronically controlled by a solenoid valve and the ECU and the high boost is controlled by an actuator connected to the turbocharger. The 4E-FTE also has a top-mounted, air-cooled intercooler. The second generation of the 4E-FE is essentially the same engine as the first but the intake and exhaust manifolds were changed along with a slight alteration of the ECU meant to reduce exhaust emissions.
This engine was discontinued in It was introduced in and discontinued in All 5E engines are fuel-injected. This ignition design uses two coils. Each coil mounts on top of a spark plug, but also has a cable run to another cylinder's spark plug. This is known as a " wasted spark design".
Toyota E engine
It is electrically similar to engines that have a coil pack. The spark plug fires in both directions center-to-side, and side-to-center.

Double platinum plugs are used with this engine to prevent premature side electrode wear. A much thinner 0. In a return-less fuel system was added. It uses the harmonic damper from the 4E-FTE, more aggressive intake and exhaust cams, some versions not the Sera have the ACIS intake, high compression pistons, exhaust headers, and stronger internals i.
