I've just picked up my new XR3i cab and someone has already fired in the EFi block from a later escort into it - I know I want to get the MFi turbo engine into it but I'm not sure what they have actually changed wiring wise to get this done.

Is it a big rewiring job to have this all done if they have had to change anything to get it running on the EFi management or is it a straight fit and forget job in a way like a normal engine replacement?

The car did originally have MFi, and then a ZVH in it a few years ago.

I know I have Sitech along the road to go to and get a look, but with being on holiday right now I wouldn't mind getting some info as to what to change, and what to look out for with changing the cabrio to the turbo engine, do i have to change any brackets etc on the engine bay for the metering unit etc.


Cheers

Neil
