Toyota 7A-FE engine reliability, problems and repair
The Toyota 7A engine appeared in 1990 and became the biggest among the A-types. It differs from the basic 4A engine because it has a crankshaft with a piston stroke of 85.5 mm and bigger height of the cylinder block. The cylinder diameter remains the same and the engine itself is an enlarged copy of the 4AFE engine.
Toyota produced only one 7A-FE type of the engine but its capacity varied from 105 HP to 120 HP. It is not recommended to buy the weakest 7A-FE Lean Burn engine type because the system is quite a problematic one; its servicing is quite a costly thing.
The 7A-FE firing order is 1-3-4-2.
Apart from the 7A engines, they also produced younger 4A and 5A motors.
The 7AFE is equipped with a toothed timing belt. The car needs a belt replacement every 60,000 miles (100,000 km) of mileage.
In 1998, a new 1ZZ engine replaced the 7A-FE. It will be mentioned later.
Toyota 7A engine problems and malfunctions
The identity of the 7A and 4A engines construction was previously mentioned. Those facts concern the possible problems, which are similar for the two motors. HERE it is possible to get to know more information on them in detail.
Toyota 7A engine tuning
7A-GE. 7A-GZE. 7A-FE Turbo
The best you can do is to devise a hybrid engine of the 4AGE and 7AFE. You will need a cylinder block, crankshaft, connecting rods (all for 7A-FE) and to buy pistons, a cylinder head, and a gasket for the 4A-GE cylinder head (all for 4A-GE) . You will have to assemble all those things and adjust them on the ECU Megasquirt. Finally, you will achieve 180 horsepower.
One can assemble the 7A-GZE with the similar 4A-GZE and 7A-FE details in a same way.
The 7AGZE engine will sustain a stock pressure of 9-11 psi (0.6-0.8 bar). If you want to intensify the pressure up to 15-17 psi (1-1.2 bar), you will need to buy the forged pistons and H-beam connecting rods.
