    Oops....sorry for the late reply. The Kameari uses the later-version distributor driveshaft with the star-shaped end, and yeah it just dropped right in. No need to force it.

      Hey, no worries thanks for getting back to me.

      I purchased the spindle gear with it so not that. Maybe I'll do a light gentle sand to try open it up slightly.

      • Now that I've done a big spruce up on the front end, it seemed a shame to stop. So the rear end comes in for some love too.

        The chromed potmetal tail light bezels had gone a little dull with the deposits from the exhaust, and without removing them, you can't really hoe into it when polishing. But once they're off, you can really go to town with a polishing ball on a cordless drill.

        The red lenses are detachable too, and the one above the tailpipe was noticeably dull. But I find that Meguiars Plastic Cleaner and Plastic Polish gets the fine swirly scratches out, and gets it looking reflective again.

        Then we move onto the engine bay. I think I haven't detailed the carbs in years, and heaps of crud and yellowy fuel stains came off when I had a go with some brake cleaner and a brush.

        ...and then you notice that the drip tray looks a little dull below the shiny carbs, so that gets a polish too.

        I'd given the piping and rocker cover a polish from time to time, but you get much better results when you take it all off and attack it with the polishing ball/drill. Barrel Bros Lip Balm polish works really well.

        The next bit was something I'd been putting off for ages, which is to sort out the messy routing of the spark plug wires. The car had come with some plug wire brackets, but I think they aren't actually for L-series, as I had to resort to all sorts of weird lengths of plug wire to get it to work, and it looked messy. I'd been meaning to buy a replacement set of 240Z plug wire brackets and clips, but they seem to only be available in USA 240Z webstores. I always thought that I'd eventually order some other parts, and get the plug wire clips at the same time. Well, I never did So I decided to splash out on the unreasonable shipping charges to get the little plastic clips sent out.

        I did get one other part though: a reproduction brake booster sticker, but that's it

        Before we start on the plug wires, I decided to make a recent addition a little more fancy. Hayashi Racing (of Hayashi wheels fame) is now making some really nice pieces for old Nissan engines; which are mainly for historic racing in Japan, where things like Tomei rocker covers for Nissan A-series go for thousands. So I had to get their billet oil filler cap. It has provision to be lockwired, and since the Hako has a big appetite for oil, it isn't the most practical idea to lock the filler cap in place...but it does look nice Check out the other cool stuff at And in Australia, you can get Hayashi Racing gear at Barrel Bros:

        I have an MSD6A CDI system and MSD8285 hi-output coil, so it was nice to discover that MSD also do universal plug wire kits that you make yourself into custom lengths.

        You get 8 plug wires and one coil wire; each one is overlong and is already fitted on the plug-side. So you have to cut them to length and fit the plug end for the distributor-end. This is the #5551 kit, with straight fittings at the plug end.

        The kit comes with different types of fittings for the distributor end...we'll need the ones on the left.

        It also comes with this super handy-dandy tool, which is used as a cutting guide for the plug leads, and can be used to crimp the fittings too.

        First you measure up the length you need, then use the cutting guide to partially-cut the wire. You place the blade at a certain spot and rotate the wire to make the cut...then twist off the excess.

        It cuts only just deep enough to expose the insulated wire core, and leave just the right amount of it sticking out.

        I don't know how well you can see this, but you fold the central wire around the outside of the plug lead, leaving a little loop so that it doesn't touch the white insulating material.

        Then stick it in the vice and crimp it down.

        It leaves a super strong crimp and're meant to slide on the rubber boot beforehand...

        And you now have a legit spark plug wire. Now to make 6 more...

        Once they're all done, test for fitment.

        And as a last step (thanks to L'Antagonista on Instagram for suggesting it), rub the white lettering off the plug wires with a rag soaked in acetone, which looks a lot more period-appropriate.

        The new 240Z wire brackets and clips get the plug leads routed really nice, in comparison to what I had before...

        Looks much neater than before, and I really should have done this years ago.

        yes, you can get off the shelf plug wire kits for 240Z, but what fun would that be? The MSD kit was really satisfying and easy to use and gets a great result.

        • One of my favourite events took place on the weekend, which was the GT-R Festival at Sydney Motorsports Park:

          It's a car show with added drag racing and gymkhana, and it's become a huge annual show that celebrates everything Skyline (hence all the sprucing-up I've been doing on the car in the past few weeks). So it's a great show with seemingly hundreds of really nice cars in attendance.

          I was too busy flitting between the events to take many pictures, but there were zillions of GT-Rs, and plenty of special ones, like this Nismo Z-Tune

          So the first order of the day was to get our parking spot in the Old School section of the car show sorted, then we hit the Gymkhana, which was a part of the dragstrip car park (which is also used for the Twilight Rallysprint series). But before this year's event, I had a go at addressing the rather extreme tail-squat that my car gets on a dragstrip launch. You might recall that I have really severe axle tramp issues if I give it some off the line, which meant that I had to baby it on the launch and then floor it, and that felt like I was leaving a lot of time on the table.

          I figured that maybe the extreme angles of the suspension arms and driveshafts might have had at least something to do with it, so to limit the tail squat for this year, I decided to extend the rear bumpstops, which live inside the rear semi-traling arm, within the spring.

          To get it out, you have to be able to prise the suspension arm low, so in order to do that the shock and driveshaft has to be unbolted, so that you can remove the spring.

          The bumpstops I'm using are shortened ones from which are intended to be an "end of the world" bumpstop for very slammed Hakos. So I actually space them up with a stack of wide washers, which brings them into play well before the shock bottoms out. But as you can see from the pic above, it does allow a generous amount of suspension travel, which results in a lot of tail squat under power. So I'm re-using a nylon spacer I made as an experiment years ago, which is the middle setup below. At the time, I was using 600 pound springs and I felt that the tail bounced off the bumpstops quite noticeably (so I removed the nylon spacers in favour of a shorter stack of washers). But now that I'm on 1100 pound springs, the tail should keep off the bumpstops a bit more and it might work. The one on the right is the stock bumpstop, which is so tall that at my ride height it would be permanently compressed.

          Bumpstop/spacer installed...

          And button it all up again. On the road, I can barely tell that they're's only noticeable on big speedbumps, where you feel the tail snub against the bumpstops.

          But it seems to work, with the Hako no longer having the comical tail-down attitude off the line. These awesome pics below have been kindly provided by Dabboussi Photography, please do check him out on:

          In terms of handling, I was worried that the tail would now be more skittish, as it would body roll onto the bumpstops early in the corner. But I reckon it's actually better: handling is flatter, there isn't the feeling that the inside front is pointing in the air coming out of corners, and while there definitely is less power-down grip on corner exit, it moves earlier and more predictably into power oversteer now, and is easier to drive sideways.

          It was only intended to be a one-weekend only drag racing mod...but I think I'll keep it for a while

          So without further ado, we drive from the gymkhana to the scrutineering booth for the drags. Interestingly the car's roadgoing weight is 1140kg. It had a 1090kg weight when I had to get a weighbridge ticket for initial registration in 2009, but that was without a lot of stuff like a stereo, toolkit, jack, spare wheel and a whole bunch of other stuff that might have been missing. And no, the weight gain is not because that guy has his foot on the weighbridge

          And we're off!

          Although...that first run wasn't without its dramas

          And did the bumpstop mod work? Well yes I suppose it did, in that we went from 14.6 last year to a new best time of 14.1 @ 102mph.

          But as you can hear from the video above, I still did get some axle tramp on the 1-2 shift. On a later run I had a go at higher launch rpm with a bit of clutch slip...but got bogged down with an excess of traction Oh well, I guess we can add drag racing to the growing list of things I do quite poorly Oh, this is my mate Brad's lovely Kenmeri, by the way.

          Oh, and as for the mechanical mishap on the first vid above, it was due to the coil lead popping off. There was quite a bit of axle tramp coming out of the burnout bath, which caused a fair bit of engine shake that pulled off the coil lead. Now I'd made the lead with a little bit of excess length to accommodate engine movement, but it looks like it wasn't enough.

          So I made a longer one, which isn't as elegant looking but at least it's more functional Thankfully the MSD Streefire plug wire kit was for a V8 and I could cut up one of the spare wires into a new, longer coil lead.

          The other highlight of the weekend was seeing my good friend Peter's new Hako on the road for the first time. Fresh out of the spraybooth, it's been a race against time to get the mechanicals ready for the mainden voyage to GTR Festival, and it came right down to the wire, with registration sorted only hours before it was too late.

          It's a lovely, lovely thing with a VERY strong stroker L-series.

          It'll be a lot of fun to see it run in anger next year

          • There's been a few really nice videos made about my Hako over the years, but recently my friend Daniel Karjadi asked if I'd like the car to be in a series of videos that he's doing for Turtle Wax.

            And I think he did a great job!

            The visuals are amazing, and we had a good long relaxed chat in the garage, which I think came through quite nicely.

            • The Hako got a fair bit of love and sprucing up prior to the GT-R Festival a few weekends ago, but there was one thing that I didn't get around to doing until after the show, which was to tidy up some of the bodywork.

              So she's looking good now...

              But there was a little damage to be fixed,

              which was from getting a cone wedged under the tail at a motorkhana about a year ago.

              And to fix some rust on the rear pockets...which aren't really noticeable unless you're under the car. The car came with them from Japan, I'd painted something onto them years ago, and they haven't gotten any worse in the intervening 11 years, but it seemed like the right time to address it.

              And lastly you might recall that several years ago I had a go at fibreglassing the cracked spoiler...

              ...and I did a home-sprayjob on it, using a rattlecan of "paint to sample"...which wasn't really a great match.

              It was a little too golden and not silver, but it wasn't really that noticeable and no one ever mentioned it.

              But now that they're firing up the spraybooth, it seemed a good time to fix it all in one go. The front spoiler came out great...hmm actually you can't really tell the colour because it's in the shadow of the bumper...

              It's a great match though.

              The beaver panel came out great too

              As did the rear pockets. My friend Col said that the rust was just superficial and hadn't penetrated the sheetmetal, so it was a simple repair.

              ...let's hope I don't mess it up again! Many thanks to Col and his team at Gordon Smash Repairs for looking after me, as always.

              • Phew. Just spent my Sunday reading this from start to finish. Pretty incredible journey for the car and yourself. Thank you for such thorough postings, pictures, and explanations! I can't imagine how you were able to put that much thought into your posts. I already can't remember what I had for lunch today. Amazing hako BTW!


                • Long time lurker, first time poster [in your thread]. Any updates? I've read from pg 1-here and learned a couple of Hako specific things...Thanks

                  Nevermind, I see on the FB group that your selling her
