    TFSI coils and a suitable loom (speak to Error404), ABY/ADU or AAN ECU and the pin swap on the ECU connector. You can keep the 3B dizzy and its hall sensor as the trigger. Hardest part is the ECU pin swap as it's a pain to do in the footwell.

    You will then need to consider what map the ECU has and your fuel pressure reg. The 3B fuel reg can be changed to a 4Bar unit from a 20v 7A engine and it's a direct fit.

      You need an ABY ECU and the various pin-outs documented here:



      Then you need a TFSI loom to replace the equivalent ABY POSs and coils.
