If it's a budget project ad ditch going for mfi m8....find a mk4 g or h plate 3i for the loom..change some wires(be a guide somewhere)..source a fiesta rs turbo lump and Ecu....mfi is out of date and a pain in the ars..it was shit then and is shit now..it's only still used as peeps want orignal cars nowadays..not saying ofab/efi is the dogs bollox but it's better than mfi and if your budget building it will help in long run....unless this is not a budget build then ditch all above and go for summit more mappable lol
