hey guys! back after an extended break!

just wondered if anyone can shed any light on this!
ive got a 1600 zetec running efi, out of the crate 100% standard in a Orion,
wondered if its possible to run a 2000 zetec fron a mondeo bare lump then bolt all the efi system to it. As simple as it sounds or am I going to run into trouble??

thanks
martin
