    3sgte into a mk3

    I know the above has been done before but cant find much info online what is involved and parts needed.

    Thanks to my over eagerness at japfest yesterday i now have a crash damaged wrote off mk2 turbo which has a fully rebuilt engine available :( pretty much all the mechanicals are fine so would be an ideal candidate to do something different with.

    Not exactly a simple conversion, in fact bloody difficult compared to others, but the basic run down is....

    1. Position engine in the sweet spot for driveshaft endfloat/ height and front/back location while keeping it perfectly level.
    2. Weld in new hanger bracket on the OS for the Mk2 engine mount
    3. Modify the NS bolt in Mk3 hanger to catch the Mk2 gearbox mount
    4. Make a combo of Mk2 and Mk3 mounts for the front and rear torque mounts.
    5. Cut out and redo the bonnet catch slam panel, it gets in the way.
    6. Use Mk2 turbo shafts but with Gt4 St185 front outer CVs fitted, you will need 4mm spacer rings between the CV and hub to keep the bearing compressed and ABS working.

    In simple terms the above gets it hung and driveshafts connected, after that you need to plumb it, wire it (not simple at all), provide it with a fuel return, build a custom exhaust, work out your intercooling and all plumbing for that, relocate the battery, and there's a few dozen smaller jobs to tackle along the way.

    Not an easy swap!
