    Today's progress:
    - New 35mm flywheel bolts to replace the dodgy ones my clutch kit came with that were too short. Bolted up perfectly this time!

    - Flywheel, cluch and pressure plate fitted.

    - Finished fitting the 6spd to the motor (the diesel box only attaches with the 4 M12 torx bolts) and bolted up the starter motor, ready to drop into car.

    I had to trim about 20mm off the e28 m5 mounts on the engine side stud and continue the threads further down. This made it slightly easier (still difficult though) to position the engine over the mounts. Like the guides say, don't bolt the mounts into the subframe until after the engine is positioned otherwise you'll never get the engine mount arms onto them.

    She runs!!
    So after a year in the making, yesterday was finally the day!



    Started first time! More work to be done though. O2 sensors are dead so need to source a replacement. Have heat cycled the engine a few times to check for leaks and all seems well.

    Now on to making the exhaust and fitting the intercooler.

    Slow but steady progress.
    Fitting the 6 speed diesel box definitely has its "intricacies" with the tilt of the box meaning the shift carrier sat nowhere near where it needed to.

    Eventually after lots of cuts, welds and whatever, the shift carrier and linkage aren't even close to resembling the original items. But finally got the angles and positioning basically spot on.

    Waiting on my shifter to arrive from the UK then I can put it in and bolt up the driveshaft and finally see this car move under its own power!

    Found (hopefully) the source or my tuning woes. Seems the cam angle sensor is in need of replacement. I knew of the weaknesses of these once they get old and knew I should have checked before fitting but I just got too excited to get it in and running.

    Anyway all the insulation on the wires is destroyed at least 10cm up inside the shielding so a new sensor has been ordered and will be here in about a week.

    lol 195s, does it even move?

    i dont have a timeframe for when i expect to be driving it. Theres just too many delays involved with getting stuff where i live despite living in the capital of Australia. i wanted it to be driving over the xmas break but that looks unlikely now unless my new CAS gets here wednesday next week.

    still wont have the downpipe and exhaust fabricated though anyway

    The new cam angle sensor arrived so i fitted that asap and it fixed the CEL.

    So i filled the diff with redline 75w90 gear oil, started it up and started filling the power steering.
    After bringing it up to temp, i popped it into 1st and rolled out of the garage! First time moving under its own power....however it was short lived. I couldn't engage reverse. Seems the shifter needed some adjusting so using the 3 socket and vice Method i bent the shift lever backwards and towards the right (its a RHD car), then popped it back in and finally had reverse working!

    Took it for a couple of laps around the block and all seems well. Need to adjust the steering wheel as it's off centre slightly but otherwise thing are looking positive.

    The clutch needs a good bleeding, as do the brakes and I'm yet to start fitting the FMIC but my goal of having it move under its own power over my Xmas Break has been achieved Click here to enlarge

    Fitted up the FMIC yesterday. Got it pretty much perfect fitment wise.

    It's a 450x300x76mm core with 2.5" inlet/outlet.

    Only hiccup is I need a longer 3" to 2.5" 90 degree reducer to connect to my maf tube.

    Those with a keen eye will spot that I have retained a new parallel core a/c condenser and the stock hose routing made to work. No fan unfortunately but we'll see how good a job the diesel clutch fan does at drawing through air at idle.

    Also safety wired the radiator into the bottom of the core support and gained about 5mm more clearance from the a/c compressor pulley.

    Downpipe done! After thinking this was going to be my most difficult job, I was incredibly lucky with getting the angles perfect first try. Yes the welds are horrible again, however I pressure tested the pipe to 20psi and found no leaks so that all that matters really.
