I was thinking of doing a engine conversion i currently have a Ef falcon with a I6 and it has a sized crank shaft and was thinking of putting the Au 6cylinder engine in there what do i need to do the swap i have been looking at some other post and I'm a bit confused i know i need to mod my sump and have to get a Au alternator. what is the go with the cam angle sensor Au engine don't have them do u just swap the Ef sensor into the Au engine or is it left out. i know the coolant temp sensor is different to but i know that is a easy fix. Can i use the Ef manifolds, power steering pump, air con compressor and if there is any different brackets.
I'm going to do all the work myself. and what it might cost me i know i can get a Au engine for around $250 what else do i need to fork out for.
Thanks for your help

Things reqired to fit AU engine to EF/EL

1) sump needs to be modified to fit K-Frame, you can cut and weld the K-Frame but that is up to you, will need engineering after being cut. You cannot use an EF/EL sump as the sump is totally different to AU. Sump Mod Thread ford-4l-and-6-cylinder-f1/au-sump-mod-for-e-series-t79648.html

2) Need to use AU/BF alternator or you will need to modify the block and drill and tap mount points to mount the EF/EL alternator.
If you use an AU I alternator you will need to change the plug for the alternator to one from an AUI as these are different from the Mitsubishi alternators.
Note: Believe that the AUII & III and BA alternators have the same plug as EF/EL.

3) Remove the block where the Dizzy (EL) or cam sensor (EF) goes and remove the gear from the shaft and fit to your Dizzy (EL) or Cam Sensor (EF). This will then mean that the gears are matching and you should have no issues, there have been issues with dizzys failing when this has not been done. Some modding will be requiered to use the existing mount point, extra notch/gring Cam sensor.
Note:Do not try and drill hole in existing EF position on AU block, you will drill through the block.

4) You will need to use a EF/EL thermostat housing as these have your temp sensor and AU housings do not.

5) You will need to use the EF/EL BBM as the uppers are different to the AU. Also us the EF/EL throttle body as some of the plugs are different to the AU.

6) Use the EF/EL wiring loom.

7) You will need to tap the block with an M12 1.5 tap if using the EF/EL Knock sensor. If using the AU sensor you will need to modify the plug.

8) a) You will need to cut the EF/EL AC pump mount spacers down to 30mm to suit the AU block as well as shortening the bolts by 10mmm if using the AU alternator to suit the standard serpentine belt.
b) If using the EF/EL alternator with modified mounts you will not need to cut down the mounts and be able to use the standard Serpentine belt.
c) Alternativly you can use the AU alternator , standard AC spacers and a Serpentine belt from an XH (Slightly longer).

9) Use the EF/EL power steering pump. This is a direct bolt up. The AU pump hose connection is different to the EF/EL.

10) You do not need to change the Harmonic balancer for either EL (Dizzy) or EF Coil Pack.

11) If fitting to EF you will need to use your original Coil Pack or an AUI coil pack as these are different to AUII & III. (different plug)

12) you can use the AU head or fit you EF/EL head, that is up to you.different sensor.

Thank you for that. thats going to help alot

Is the VCT engine the same for the engine swap or is the more mods and stuff thanks

Not worth the hassle. Use a good low Km AU block.

Is all the stuff you said before the same for an au engine into an ed?
cheers

ed doesn't need modified sump, just grind the fins off.

cheers for the help guys just got myself a low km's stained au engine now to get the sump modified
