Just wondering, without much fuss, if it's possible to drop a naked AU engine into my EL (non-AU hybrid)

Just replaced the dizzy, coil and ignition module and except for the leaking head gasket wondering what else could go wrong with my poor little car

It is possible, there are plenty of threads on this, do a search

Biggest issue is it won't actually fit without modding the AU sump, by cutting a chunk off the front at 45 degrees and welding on a flat plate. It won't clear the front crossmember.

Little more fussing, but if you're not keen on cutting part of your car out, get your old EF Sump and replace it with the one on the AU engine.

wont work, the au sump has cross bolts from the sides

Agreed, not at all possible.

if you can be botherd and have the time and paintence, would be a good idea to do it, but if you need it back on the road asap or cant be botherd just do the head gasket

Will be happy to supply pictures of an EF with an AU motor utilising an EF's sump on the weekend; alternatively, PM SV-Valiant as he has done this.

Will be waiting for them,

it is probally just as easy to pick up a spare sump, drop it off to a welding shop, give them the measurements, pick it up a day later and its ready to go,

Then stuffing around trying to get the ef sump to fit a au engine

How did he go about it? Just not even bother with the cross bolts or something?

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.

2) Need to use AU/BF alternator or you will need to make up adapter plates 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. 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.

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 to take the EF/EL knock sensor, AU's use a different sensor.

8) 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 to suit the serpentine belt.

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 EL (Dizzy) but you will need to fit an EF balancer if using 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.

Hope these points help, if you need more info please contact. I have an AU engine here now that is ready to be fitted to an EF on the weekend.

Wrong i cut my K frame on my EF to suit the AU motor and AU Sump cant use the EF sump on a AU motor

now the truth be told. cheers S- Valiant

Sorry, could've sworn that was what he did. That comment is rich coming from you though Matt; 10 day build much.
