    KMiata SCCA Solo XP swap

    Got the cooling system pretty much wrapped up, I think. Probably going to put some more anti-abrasion sleeve and a bit of retention where it wraps around the front of the engine, because while it doesn't touch while not loaded, I imagine when it's full of water and moving with the car & engine...

    KMiata SCCA Solo XP swap

    It's no secret that I don't like the way they tension the accessory belt in this swap. I absolutely believe them when they say it works and is reliable on their & their customer race cars, but I picture myself in a wet, gravel or sand paddock space at a track or on the side of a mountain...

    KMiata SCCA Solo XP swap

    Had the day off. Ended up burning most of that ferrying a kid to the doctor (yay strep throat!) but managed to get in the shop for a couple hours to knock out a few things. 1st up was fixing the clearance issue (another V8Roadsters hit!) between the 'intermediate' header pipe flange and...

    KMiata SCCA Solo XP swap

    I wanted a way to run the upper radiator hose for the K24 from the driver's side rear of the head under the intake manifold and forward to the rad. I, at this time, will need 3 different hoses / tubes to make that happen (90 deg rubber to turn the corner to run under the intake manifold, a 90...

    KMiata SCCA Solo XP swap

    This happened today. Of course after I finish up all the hose routing, it all comes back out again to fix a few issues and get nut-and-bolted (again), but it's a big step.

    KMiata SCCA Solo XP swap

    Eating the elephant 1 bite at a time. I should have it mocked up in the engine bay tomorrow so I can bolt everything in and finish running fuel lines, start running coolant lines, and generally figuring out where everything wants to live.

    KMiata SCCA Solo XP swap

    I'm normally not shy about getting out the cutting tools, but hacking into a nice, cast aluminum bell housing (even if it's to an empty case that I have for exactly this) gave me the heebs. That said, it's serving its purpose (mockup), and I'll know how to do the quaife box a good bit better.

    KMiata SCCA Solo XP swap

    Fuel system progress. I need to close the holes in the package tray up, and a couple spots need chafing protection. The reg and filter took up way more room than I was expecting, hence putting it all in the trunk. This one'll also be getting a panel to keep rocks from the tires away from...

    KMiata SCCA Solo XP swap

    woohoo I've made my first AN line! ....god I hope they don't leak :lolsob: 2 more down. Gotta wait on the rest of the fittings to come in later this week. Also waiting on some line separators to keep everything tidy and from rubbing anything it shouldn't. I was trying to figure out how...

    What have you done to your Miata today?

    Finished up the RacePak dash mount with a gusset & finished welding it: Installed a Walbro 450 pump and swapped from the NA 1.6 to NB 1.8 fuel sending units. The main reason for the swap is that it's WAY easier to adapt the NB's quick-connect fuel fittings to AN fittings, because these...

    KMiata SCCA Solo XP swap

    This is a Walbro 450 that's going in. This The only thing I think I want to do different at this point is add another worm clamp to make sure it stays put, and extend the return tube with some rubber line. I'm swapping to an NB sender because the ends above the tank are SAE quick connects and...

    KMiata SCCA Solo XP swap

    I finished up the mount for the RacePak. Added a gusset and welded it out. For whatever reason it looks crooked when sitting in the seat, but I checked it with an angle gauge and the cowl of the car, the dash bar of the roll cage and the top surface of the dash mount are all within a degree of...

    KMiata SCCA Solo XP swap

    As is usual with non-standard builds using non-standard parts, it's a matter of working through 1 small problem after another. The KMiata swap is likely no problem if you use all stock Honda parts, but throwing oddball stuff into the mix tends to have knock on effects. Case in point: Water pump...

    What have you done to your Miata today?

    I never got the fascination of 'car guys' about a generation older than me have with the old school Stack dash that was in, like, every race car 'back in the day'. When I was coming up and starting to pay attention, it already looked old and dated. When I was coming up, all the big GT endurance...

    What have you done to your Miata today?

    I'm at that depressing point in a new build where the car looks like it's more ready for the scrapyard than to be a race car again. The front end's cut out, half the panels are missing, bits and pieces are notched and cut here and there, paint's missing all over the place, wires and hoses...

    KMiata SCCA Solo XP swap

    The engine's basically ready to come off the stand so I can notch the bellhousing for the starter. Other than that, it's ready to go. Now to start with fueling. So...that's gross. It's not a rats nest (despite looking like it). Other than the leaves there's no other sign of life in there...

    KMiata SCCA Solo XP swap

    Been chipping away at a bunch of small stuff, but pieces are starting to fall into place. Apparently they now have a 'universal' upper coolant housing that doesn't need to use the Miata's stock temp sensor, but I didn't know that, and I've already got this one (and a Miata coolant sensor...) so...

    Finished my bolt-in bumper bar solution. I'm really happy with how it came out Started by boxing in the ends of the frame rails where the bumper bar was cut out: And boxed in the ends of the bumper bar: Then welded the 'paddles' on that let it bolt up to the chassis, and hit it all with...
