EFI would be more reliable, but if you bought the whole Rs Turbo lump ie, brains, wiring etc then just put the whole lot straight in. The MFI is a bit of a bodge up by Ford but i wouldn't say it was bad. As it's a Mk5 Fiesta i don't know how easily it would fit, it may need custom mounts etc i don't know really, but a CVH isn't a difficult engine.
