Hello guys I'm going converting my 1.25 2001 fiesta to 1.7 . By reading previous threads it doesn't seem too tedious, I bought a puma kith engine and box 2001 also, for a donor car. Will there be any serious problems encountered, I know the engine loom and ecu have to be changed on visibly engine but is there. Any wiring, fuel suspension anything else that will have to be changed? And last question is it possible to do this conversion in a day? Thanks for your time guys
