Hope someone can help me out, I have a mk3 se cab that I want to zetec, I have the engine but confused as to which loom, ecu and inlet would be best, may turbo at later stage too, have read a lot about the conversion on here and other sites but has probably confused me more if anything, I have carried out a few 3i - turbo conversions before which is pretty straight forward but the efi part is where I'm stuck, any help much appreciated, thank you
