    Engine is finally in. What a nightmare that turned out to be. :( Had never put the engine in complete before & had never put sump on mockup engine. What a mistake that was. :cry: Lots of small jobs done I wasn't looking forward to due to my error. Subframe bolts freed off, steering rack bolts freed off & anti-roll bar freed off.

    Had to make a small bit of clearance on the subframe for the sump, but just glad to see it in.

    Now the fun starts, wiring & piping it up next. [:s]

    Will need to update the times, have them all wrote down in the garage.

    Cheers John

    I wonder if it`s worth putting a small damper / mount higher up the engine ? The gap it sits into it`s that big and with the mounts being so low on the block, it`s bound to move side to side. Last thing you want is it hitting the bulkhead as you accelerate or brake ?

    The engine looks to be almost behind the turrets on that pic :thumbup:

    That sounds like a good idea. Never even thought of that. Mounts are very low. Cheers for that. :thumbup:

    Engine does sit behind the turrets, only a matter of mm's forward of the rotary. That was the plan from the start, to try not upset the handling of the car too much. Has gave me a few headaches though. [:s]
    Standard strut brace fits back on. ;)

    Started to get some of the pipe work sorted. I thought I start with the metal pipes on the engine. Started with the Passat top pipe.

    Was going to interfere with the manifold I'm using.
    [​IMG]

    With a simple bit of cutting & welding, it's sorted. I hope.

    I've also made to bottom pipe fit my application, but forgot to take pics.

    Times also updated on the first page.

    Cheers John

    Not had much time to work on the car the last couple of weeks. Been busy getting the retired track car out of hibernation & ready for a rolling road day. Back on it over the next week.

    The car the rx8 is replacing on track.

    Fitted the starter today & checked that it would still engage with the modified flywheel. Was chuffed to hear it turn over.

    A few small jobs done today.

    Blanking plate fitted to the rear of the head.
    [​IMG]

    Wiring all connected to the engine, think I'll be able to fit it nice & tidy with minimum work.
    [​IMG]

    [​IMG]

    Piped most of the turbo up temporarily, with the pipes I have about. Just so I can try & test fire it before going any further.
    [​IMG]

    Plan is to pipe up the rest of the intake side of things, try & test fire it for next weekend if I get time & get ECU back. Getting a bit nervous now. If you can spot anything fitted wrong please let me know.

    Cheers John

    Unfortunately not really much to report at the moment. I'm still waiting on my ECU coming back. :-k

    Just thought I'd post to let you's know the project is still ongoing.

    Have spent some of my time helping some friends compete at knockhill. Which lets me play with some interesting cars.

    Also a few mods to the fiesta that we built last year. Arches rolled to get bigger wheels on to allow for a brake conversion
    [​IMG]

    Did get a couple of jobs done to the rx8. Drilled & tapped the rear of the head to take an outlet that suits my application.

    Messed about with the water pipes a bit till I was totally happy with them. Will update times ASAP.

    Almost forgot, got some tail pipes FOC for me to start making the exhaust. Should be big enough. :lol:

    Ordered these today so I can start to pipe the breather system. I've got no room to run the standard setup, so will run a catch can. Anyone else running one & used these fittings before?

    [​IMG]

    Hope to get my ECU back today at some point. Done or not. Been away for over 2 months now.

    Cheers John

    Been a while since I've been able to work on the car. But finally got the intercooler in a position I'm happy with. Had to remove the front crash bar, I'll make a different one up. Didn't realise the intercooler was this big.

    Started to mock up the boost pipes. Even made my own bead roller of sorts. Should do the job.

    First boost pipe just about mocked up.

    Hi Pete, I've seen your thread before on a few forums. But thought it had been abandoned due to the lack of updates. Glad to see its still on the go.

    The dials just need to see a feed from the crack pickup from the rx8 engine. But you probably already know that. I removed the trigger wheel & mounted it to the front pulley. Had mine fired but not tried the gauges yet. Just starting to make my exhaust manifold. Will need to update the thread.

    Cheers John

    That was my plan yeah, wasn't sure if it would give a correct rpm due to the crank being eccentric and not as a std crank? Would it not show 3xcrank rotations due to the 3 cylinders? As opposed to one revolution on a std crank
    You still running the rx8 rack? I've ditched it in favour of an mx5 item.
    But that involved extending the tre and the steering column haha.
    Pretty much nothing is bolt on on this project

    No, just shows normal revolutions of the eccentric shaft. 1 360 turn of the trigger wheel shows 1rpm. Nothing to do with the amount of cylinders. ;) Plan is still to use the rx8 rack. Got in touch with a guy through the rx8 Facebook pages that's done a ls1 conversion. He's done a lot more reserch into the electrics & gave me the info about the power steering only needing to see the rpm signal to work. [:D]

    Cheers John
