    I want to wrap the dump pipe as the temps under the bonnet are getting really hot. I will also look at a small spacer between the bonnet and the hinge at the back to give a bit of a gap for hot air to escape. Similar to what Ben did on his Cresta for drag week.

    Put the Kelford cams in, springs, shimless buckets and ARP head stud kit.

    I bought an RT142 Corona diff, around 3.58:1 ratio compared to the 4.1 that's in it now. It should help with highway speeds. I also wouldn't mind a 1 piece tail shaft.

    Then more boost and possibly e85.

    Little filter added, mod plate booked for Saturday. Wired in the relay for the air conditioning so will need to get it recharged and hope it doesn't leak.





    Changed the MAC valve location now that I the oil air separator is removed, exhaust valve venting straight to intake like factory. I need to find a little filter for the MAC valve. If anyone reading this on the Gold Coast has one spare feel free to PM me.

    Re did the hot side so I will have a bit more room to fit a filter. I also removed the Moroso separator and will run the breather line directly from the exhaust cam over to the inlet of the turbo. I think it looks much better and frees up more space.









    I might upgrade my tig welder, something with a higher frequency would be great.

    This makes all of the right noises.

    Good that you got it sorted, pinion angles can be a nightmare to fix if you don't have room to move

    So I ended up raised the rear of the transmission about 12mm which made the pinion angles much better. I did a bit of hunting around with google and people experiencing similar issues rectified it by unbolting the converter, turning it, and bolting it to a different bolt hole on the flexplate. So after doing all of that the vibration is pretty much gone, still a very slight one, but cruising around at 80km/h @ 3,000 rpm is so much better now.

    Good thing about a wet road is that you don't really have to worry about breaking things,..

    I've had the tail shaft checked over again, a bit of run out in it which was fixed and also re balanced.

    I still have a super annoying vibration around the transmission area around 3,000rpm so I will pull the transmission and converter out and rev the motor without it attached to trouble shoot.

    Very frustrating.

    Also ordered a bunch of stuff to put a proper filter on it so I can have it mod plated.

    The upgrade must be a few dollars then.
    Seems a shame to throw it in the bin.

    Wait for it to break, pull everything out , send the shell to sims metal and put it in something newer.

    What decision on diff? Vibration looks very annoying.

    New converter seems to have made a huge difference. Have a vibration around 3,000rpm so will have to get the tail shaft checked again. Then off to Spry for a check and more boost. I bought a set of Kelford Cams, 272/278 degree. 9.95mm lift. So I will eventually get my spare cylinder head built up and ported to be installed and start looking a set of forged pistons and rods for the bottom end.

    Seeing that the forum issues removed previous video,



    Quick inside vid with an old gopro - was hoping the sound would have been a little better.
