Bumping this thread as i have a simialr question.
I currently have a mk1 focus 2.0 zetec. Ive just bought a focus rs engine for a conversion. What is the best way to get this running? Can the 2.0 zetec ecu be mapped to suit the focus rs engine? Or do i need the focus rs ecu to start with?

did he change his wiring loom etc or did he drop his frs engine and had his original focus efc remapped?
