    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.
