Helo everyone,

Since I got bigger plans for my AU< i wanna get another car, however the work I have done to the I6 AU engine I dont wanna go to the shits. So I was thinking of getting an old EF Falcon of any sort and transplant the engine out of the AU into it. As far as I am concerned the engine mounts should be identical, however the reason why I wanna look at an EF is due to the wiring harness. The EFs were the first to use the variable length intake system.
My Question now is will the EF wiring harness be good enough for the AU engine to run or would I have to take the AU harness with me? If that is the case I my as well get an ED and transplant it into that.

Second of all is I got a T5 sitting at home which i cant fit to the AU, as they use a longer type, and i only got the older shorter transmission. In short words the T% is out of an EA, I presume I would need a new bellhousing to make that fit.

Also I wanna take the AU ECU with me into the new car, I know that the plugs for ECU havent changed since the EA to the AU, however converting it from Auto to Manual, should i reflash the ECU with the manual program? Mind u i got a custom ChipTorque chip on the AU ECU sitting ATM which has already giving me a fair wack of grief.

Any ideas and answers to my questions are appreciated.

Cheers
Mic

that could be tricky conversion

I would be more inclinded to leave it where it is. EF-AU almsot identical across the range
but the manual to auto situation in these cars is worse the Torque control that's used in the ECU is there to keep both auto and manual boxes alive.
A long think about it is all I can say

I do know a guy who used a wreaked Au XR6 motor and dropped it into a XR6 ED with VCT now with a powerdyne charger on board but it was never smooth sailing, espcially with the auto's i think he ended up with a very worked C9 box
