If you're running mfi then just swap everything over on to the new engine. inlets and exhaust. a cvh fly wheel is needed and the holes need to be drilled out, but any engineering company can do this for afew £

I do have efi inlet +adapter so you would need a loom and ecu from a fiesta. i am running megasquirt.

Not sure what spec the turbo is, but i think i will keep it for the zetec engine.
