    late audi box mated to T5r volvo engine

    i also rigged up an old pedal box to check clutch lift /travel and its works ! next move is a 5 segment rotor to fit the end of the exhaust cam to fire the audi tch ignition module and a movable backplate with the hall trigger so i have manual advance retard

    I sort of wish I knew what any of that meant!
    The only guess I can make is that it should probably be horizontally fitted - but only because it looks too tall to fit under a bonnet!

    My last "big job" on the van, was to replace a wing mirror that someone knocked off, while i was parked up.
    Had I realised that you have to take the inner part of the door off, I probably wouldn't have tried - loads of hateful breakable clips!

    I'm far too embarassed to admit how long it took - but it's done, now!
    As you all might have guessed - I'm not a mechanic - my "expertise" lies elsewhere!

    But it looks good, considering you're somehow combining one engine with a non-standard gearbox (from a totally different car!?), along with christ knows what else!

    I've seen inside a gear-box before (that some-one else was working on - might I add!) and it resembled the 7th circle of hell - a proper horrific mess of varying-sized cogs, which obviously have to be in the right places!

    He got it back together, too - but I've no idea how.

    If my life depended on fixing anything like that - I'd be dead!
    Good on you - I seriously wish I could do that sort of stuff.

    All the Best,
    CJ

    That should be a pretty good substitute. T5 is lovely engine, nice and torquey and very durable. There are loads of cheap ones about too

    made the rotor for the hall trigger , welded on a strip of steel , 30 amps with the unit over a ,socket , the same diameter ,
    superglued it to an audi 5cyl one and scribed the sections and cut and filed as acurate as possible
    have to position it in relation to the distributer rotor arm and make allowance for about 34 degrees advance by manualy moving the hall trigger housing so in effect i will be the anti knock and boost retard
    those of us with old bikes like manual advance and retard it, used to be a party trick with chauffeurs of old rollers setting the engine up just after tdc then quickly moving the A/R lever to flick the points and it would start 20200108_164627.jpg

    set about making up the ignition set up .
    A ball bearing holds the hall trigger via a flat spring 'an old steel rule , this allows it to move around the rotor to adjust the timing
    the hall trigger is a 3 wire one and it works with the ign module fine ,ihad it mocked up on the bench and big sparks when i passed a metal blade past the trigger coil . A 20200109_130025.jpg nd finally all the bits so simple these modules were used on most of the european cars in the 80s before the ecu took over to control timing ,they can be used on any engine with a bit of ingenuity , i couldnt use the flywheel trigger as i had to remove all the trigger teeth fr om the fly wheel to clear the bell housing

    20200116_161318.jpg 20200116_161436.jpg managed to make a rising rate fuel regulator
    out of a new industrial regulator originaly for instrument air or gases. diaphragm is viton so it should be fine with most fuels .
    With a carb blow thru system it has to have a normal fuel supply pressure on idle, ive set it at 3.5 psi with most of the pump pressure being diverted back to the tank via a return pipe ,the main pressure held at 25 psi
    the pump gives 40 psi


    When you boost it the supply pressure has to be above the boost pressure so pressure is fed in at the top of the unit with the pipe i added where the spring lives and in turn raises the supply pressure progressively
    The small pipe feeding into the dome i added has a non return valve so when the engine goes back down to idle it stops the diaprhagm lifting and dropping the pre set idle pressure being held by the spring inside.
    The fitting on the botton has a restriction hole to control the main pressue at 25 psi while diverting some of the fuel back to tank should help to keep the fuel cool too and save vapour lock
