Tech:Engine/A Series/Converting to RWD
Converting A-Series engines to RWD can be done.
List of things that you might want to consider when installing a 4AGE based engine into an KE70/AE71/AE86.
Engine Crossmember - You can use the engine crossmember from an AE71/AE86 as the engine mounts will bolt straight up. If you have a KE70 crossmember, you will have to get custom engine mounts made.
Gearbox Crossmember - You can use the gearbox crossmember from an AE71/AE86 as the gearbox mount will bolt straight up. If you have a KE70 crossmember you will have to re-drill some holes to mount the gearbox.
You can use the engine mounts from an AE71/AE86 4A-C engine or have some custom made. Realise that custom made engine mounts require engineering.
Flywheel / Clutch / Pressure Plate / Throwout Bearing
There are 2 different size 4AGE flywheels, for 200mm and 212mm clutches. If yours is the 200mm clutch, just buy an AE71/AE86 200mm clutch kit. If yours is the 212mm Clutch, you will have to buy an AE92 100KW 4AGE 212mm clutch kit (also you will have to buy a throwout bearing from an AE86, as the AE92 clutch kit throwout bearing is completely different).
FF / MR mount 4AGE engines do not have a spigot bearing in the crankshaft. You can press a spigot bearing from an AE71/AE86 4A-C into the crankshaft.
