    Glad you're up and running! That TB connector has gotten me a couple times over the years, escaped my mind on this one.

    the thing that gave it away was along with the code, there was no sensor information while running diagnostics with forscan.

    It could be a normal sound as I am not used to this engine and I cant hear it in the cabin (or probably even with the hud down but havent tried that yet) but there is a slight clicking - probably just the injectors but you guys seem to be experts so a second opinion would be welcome!

    The sound is normal. Direct injectors are noisy

    Very noisy, welcome to the sound of the engine. Now if you start hearing a metallic slapping or rubbing noise you've got problems and your timing chain / vvt is past due for service

    Does this actually run? Would like to see some clips of this thing in action. Has anyone even done this before? Only other DISI transplant I can think of is the Mazda5 that Motor Trend did more than a decade ago.

    Answer is "mostly" - it runs, drives, passes UK regulations (MOT) still working through some issues as can be seen in other posts. I dont belive this is the first one in a mk3 but I do belive this is the first right hand drive one - I just tried looking for the forum post but cant find it, the inspiration came from over at miata.net forums
