    What else do you do on a rainy Melbourne day? Spend the whole day in the garage....
    It started as a garage cleaning day, but after I put oem wheels and suspension on the carbon fibre MX5, it could come off the hoist. Then the silver MX5 went on the hoist, and I started pulling off all the bits I don't need. Did the diff swap, and started stripping the motor so I can put new seals, timing belt, etc on. Next was clean up the rocker cover, I grabbed the wrong can of paint, it was supposed to be wrinkle red, but I accidentally picked up Holden red engine enamel. Probably looks better.
    Still a lot of work to go..

    Bit of an update.
    Timing belt, all seals, water pump, engine mounts, etc has all been done. Clutch and flywheel are done. I had to strip the interior so a full cage can go in. It was booked in with McQueen Motorsport yesterday, but he wouldn't answer his phone. Kind of annoying when you don't have much spare time, and dedicate a full day making sure it's ready on time. I didn't want a full cage, as this is a road registered car. But he is building the full cage for not much more than a quality rollbar.

    Do you think a light flywheel is worth it on a $/sec basis?

    What time do you think it's worth on a lap of PI on otherwise stock engine???

    Cheers

    Might not make a big difference to lap times, but it makes it much better to drive when down changing/ rev matching. I just like it.

    There is an actual horsepower advantage to running lighter flywheel and clutch.
    However if it makes you feel good.... well driver comfort and confidence is equally as important as any other mod.

    On the Swift, which has similar power and weight to the MX5, went from the stock 7.3kg flywheel to a R's 4.3kg, made absolutely no difference to lap times, and could barely notice any difference. Least worthwhile mod to date.

    BTW, very jealous of your MX5, the boys in the Sprinkles household wanted to get one as a track car, but the Minister of Finance and War would not authorise a 2 seater. That's how we ended up tracking Swifts.

    I always go for a lightweight flywheel, and I am amazed it made no difference to your car. On my first 1.6 turbo MX5, I went to a bigger, heavier flywheel. And it actually felt like it pulled a lot harder initially. Every gear change felt like it put you back in the seat more.

    Bit more prep for the cage- the windscreen has been removed, as well as the seat belt towers and ECU cover/footwell rest. There are security bolts on the cover, so had to grind the bolts off.
    Seat belt towers are in the way, and not needed as I will bolt the seat belt to the main roll hoop.

    Also removed 10kg's of fat from myself. I started to put on some weight getting to 94.6kg's, now down to 84.6kg's. At 6'2" I am not sure I want to loose any more.

    I will load the car on the trailer this morning, and take it down to McQueen Motorsport for its cage later.
    I had some time to work on the car, so I installed the radiator and had a crack at the intake. After much thought on how I make a new intake. I figured I should just cut the original long intake up, just using the 90 degree bend and flip it to face the other way. So cut the section off, but it wouldn't slip over the AFM. Tried boiling water, then stuck it in the oven for 10-15 minutes. Slipped straight on. Cost me nothing, so very happy.

    Just to be annoying I will update this. The car is at the rollcage place, deposit payed so he can cover the materials cost. And he says 3-4 weeks before it will be done
    We decided on using the Oem dash bar so I can run the A/C and keep the dash intact. I will check in and see how it's going in a fortnight. I just hope 3-4 weeks doesn't turn into 3-4 months. Payed a years rego on it, and haven't driven it in the road since. Plus I just want to get it on the track and see how it goes. If. I could get it ready, and find a driver I would be keen to do the Phillip Island 300 race with this car. If I could consistently do 1:50, it might be competive as it will use no fuel.

    Liking the thought process behind this build/track prep.

    Good, cheap fun. Hopefully not spoiled with too long a build on the cage.

    It has been spoiled by the cage guys.. I will shorten the story as much as I can.
    Scott ended up not doing the cage, it was a shit fight to even get the car back. He basically couldn't be bothered. In the end I drove out there and spent the whole day there until I got the car.
    Then I had to find another cage builder. We found a guy that seemed pretty good, price was good, and seeing as I have too many cars and this is a budget build, I didn't want to spend $4-$5k on a cage. So thought it was worth trying him. Rick dropped his car off first, we picked it up last night. After a good look at it, I think the whole cage needs to come out. My car is at the rollcage shop now. Looks like I will have to pick it up in the morning before he gets to work on it. I can't take the chance he will do it right. Rick now has paid for a cage he will spend a day or two taking back out. The welds don't look the best, and the bars are not in the right spot.
    Both places are a good hour away, so lots of wasted time. We even trailered my MX5 with the Meridian cage for this guy to look at, take pics and copy.
    I will have to put this back in the garage and leave it for a while. I don't have the time to work on it/drive it around now. I wish I didn't get talked into putting a full cage in it. This was supposed to be a quick simple build.

    Who was the second cage builder so other people can avoid the pain you are going through?

    Got any pics of his work?

    Wouldn't have saved a lot of fucking around and money to just go the tried and true AGI cage first up.

    I will upload some pics. And I can get the name, but I think he will stick to what he is good at- building trailers.

    I don't want to spend $4k on a cage for that car right now. I will just put a half cage in it, and later get a full cage.

    This is a true sorry, but it will sound made up.

    I was driving along on my to pick up the car, and a truck hits my trailer because he didn't see it. He just kept on changing lanes even tho I had my hand on the horn. I had nowhere to go, so the tyre gets ripped on the side wall, the guard and lights, etc get smashed along with the rim.

    About an hour later, a woman drives out of a driveway straight into the other side. It's bent the arm that holds the wheel, so now it has aggressive camber. Another smashed guard, lights, etc. It ripped the plastics and stuff off the front of her car. I don't get how she couldn't see my bright wagon, or the car on the trailer. It is Broadmeadows area, and she looks like a fairly new import. She won't give me her insurance details, so now I am left to get a solicitor I suppose.

    You have her licence and car rego number???

    If so just go through your insurance. It should cover your trailer as well as car.

    Obviously do the same if you don't have the truck driver's insurance details.

    You will probably have to put two claims in if you have to go through your insurer.

    After a second chat to the guy that made the trailer, it turns out I just need a new stub axle. Plus 2 wheels and tyres, guards, etc. I rang insurance and police, they said it's a civil matter and as the trailer didn't have its own insurance it's up to me to try and get the money.

    That's shit.

    My policies cover trailers I tow.
    The Shannon's policies I have for most of my cars cover trailers being towed and the policy I have for the work ute with QBE also covers trailers. Both of them for the damage a trailer may cause and also for damage to the trailer, albeit only up to about $1000 or so from memory.

    $200 a year for full insurance on my car trailer. Excess is $400 for at fault or theft. Insured for $3000. Seemed like a good deal.
    I have stuff...

    It turned out the trailer is slightly bent around the swing arm locating point. And seeing as the trailer can not be repaired locally, and it is not financially worth while getting it repaired by the manufacturer in QLD. It was deemed a total loss.
    So after 6 or 7 calls to her insurance (about an hour per call), jumping through hoops, and being asked to provide extra info after each call, they finally payed out the trailer. Took me a few weeks, but a good result in the end.

    Now back onto the car. I hate that this car was just left down the back of the garage, so lately I decided to spend some time on it. Just half an hour here and there between other jobs. But it's enough to get it done eventually.
    Seeing as it is no longer a street car, more of a registered track/race car, the whole hvac system is gone along with the P/S bits. I reconnected all the wiring so that it would run, but it wouldn't start. The Beavis came around to help, and after a while we found it was just the rear loom was not plugged in, so no power to the fuel pump. It now starts and runs fine, as it should. It only has extractors on it at the moment, so it's a bit loud. Braided brake lines are all done, just need good pads and bleed it with good fluid.
    I will bring it down to my mechanic (Lux Racing) and he will put the cage in it. So hopefully will be done in the next few weeks.

    I trimmed as much weight from behind the dash as possible. Started tidying up the wiring too, just getting things done while its waiting for a cage, will still be a while away. I might just get it ready to drive as is without the cage for now. It's not like MX5's roll over very often.

    Light is good for cheap track car. Any ideas on how much weight you have taken out? Will be cheap fun.

    No idea how much weight has been taken out, but at a guess the car should weigh under 950kg. I went down and bought the exhaust bits today, and after dinner I went out and did some chopping and glueing of metal tubes. It's amazing how little goes into it. I bought 1m of straight tube, one 90 degree bend (was enough to do 2 bends and have left over for the exhaust tip), muffler, hotdog, flange and flex joint. All 2.25" and cost $250 in total.
    Here is a pic next to the 3" I made a year or so ago that is going on the black car soon.



    The car would only need a set of wheel now to be driveable. But I want to buy some Hawk blue pads, bleed the brakes with some dot 4 fluid, get a steering wheel and quick release. And a fastback of course...

    The exhaust is welded up, and bolted on. It's a little raspy sounding.

    I have a cage in it now. It should be ready to use by the end of the year. I hope..

    Good progress after the cage delays/stuff around.

    Great to read it all coming together, not far off driveable.
