    Got around to my gearbox oil change. Both filler and drain plugs came out without too much resistance. Glad I changed it, it was old. Slight green tinge but fairly dark/black. Put in new Millers Pistoneeze classic gear oil EP GL4 80W90 and it now shifts more smoothly. I took out about 1.8 litres so put back in the same. Took it out for 30 miles today on an essential trip and hse drove lovely.

    Yes, I like the map light, it is intermittent through. Another connection to clean up!

    I machined up the prototype outer drive shaft coupling today, left it a bit long on the inner face in case I need a bit more , can always machine it back afterwards just need to cut the splines now,

    That looks great, I had to make do with making adapters as I couldn’t cut the splines, must be great to have access to the right tackle!! 725868B8-627A-4AE1-A44D-E8F68C1C7133.jpeg

    Well I’m making steady progress in getting the car back together.

    I'd like to see a longer test on the road up to 70-mph. I just can't imagine driving with a 4.44 on the road (fine for circuits and rallies).

    That’s real short, is it not a step too far? What’s mph/1000rpm in top?

    I have been using a 4.11 LSD for the past few years Rob, motorway cruising @ 70 MPH is around 3750RPM with my S13 box and tyre combo, with the 4.44 its moved up the RPM a bit around 4000rpm. But I'm yet to take it for a proper spin as we are still not aloud out in Wales , only been down my workshop down the road , but I may take it to work next week to test it on the motorway,

    My ideal set up would be quick up to 100MPH , goes round corners well and stops really quick and can cruise on the motorway as 70MPH without 'screwing' it and going deaf from the noise, it a bit of a compromise sometimes but that's what I aim for , and I do have a spare 3.54 LSD diff if I want to drive all the way to LeMan classic .

    Saw it in FB yesterday Gary - I flippin' love it!! I'd think that should be monstrous fun to drive and it sounds brilliant. Nice job.

    Look at the 4.44 as a license protection mechanism :) .

    I was looking the other day at a 4.6 vs my current 3.7, and it really only raised the revs about 1000 rpm at 70. I wish I'd bid more on the 4.6 :)
    the 3.7 is a bit under 3k at 70 whereas the 4.6 would be about 3.8k

    I can understand the thrill during acceleration but once there a buzzing engine is like having a wasp in the car. Also I imagine 1st gear is really 'short'. Anyway I've had this conversation with 'franky' and we agree to disagree.

    I think its the perfect combo there. you haven't built your car to sit at 70mph on the motorway. Sitting at 60 is no hardship, then you've the thrill of having a car where you can really drive it everywhere else. What the world needs is 5th to be an overdrive, so 0.73 etc. like a rocket box.

    franky, you can really drive any modified Z anywhere else - they have gearboxes. If I want the experience of a 4.44 diff I'll just use 1 lower gear than now but still have an overdrive. Anyway we won't agree.

    We don't need to agree Rob, we can both like different things, doesn't mean either of us are wrong.

    The best box would be where 2, 3 and 4 are close. 5 overdrive.

    An Imp is doing 4k at 60mph and have regularly held it at 70+ for miles. If the engine note is right and the car loves to rev it's pure music.

    The S12 boxes have a 0.76 5th ratio IIRC ,

    My engine comes on cam at around 4k so if I can cruise on the motorway just under that its pretty quiet and when i put my foot down i can overtake easily,
    I built my car to enjoy the roads I have near me , nice A &B roads in the mountain's were you spend most of your time in 3rd & 4th and you need good brakes that don't over heat ,

    Everyone has 'their' perfect set up, doesn't mean anyone is right or wrong , as long as your having fun that's what matters

    I love Welsh roads. In the early 70s nearly all my rallying was in Wales.
