In the meantime, I pulled all the control arms apart, pressed all the bushings out, wire wheeled any flaking paint or rust and gave all them a coat of paint. I ordered a set of IL Motorsport rubber bushings from F.M. but they are on back order right now. I'll visit this stuff when the car is closer to rolling under its own power.

First step is to strip all the wrap off the loom and see what I need to keep. I really need to get my Holly ECU and engine harness before I start cutting shit out of here.

I was tired of the gas tank taking up room in the shop so I went ahead and got it buttoned up with a Deatschworks 255 pump. While I was in there, I cut the flange off the internal regulator and TIG brazed a piece of SS tube to it so that the fuel returning from the Corvette filter/regulator would go back into that little cavity where the pump sits.

On the note of fuel, I priced out all the pieces to do an AN fitting fuel system, and it was going to be about $250 of just adapters, fittings, and hoses, or $400 something for the V8 roadsters kit. I'm not finna fake for these peckerwoods, so I just did some research about the OEM nylon lines and decided to make my own using off the shelf repair parts. The press tool to make these lines are expensive too, so I made my own tool that takes advantage of a vice.

The OD of the nylon hose is 10mm, so I just grabbed a 10mm drill bit, drilled a hole, then ran a M10 x 1.0 tap through the hole to give it a little bit of some bite on the hose. It leaves some small marks, but not bad. Note: I had to fix my press tool by cutting one of the halves off completely and drilling another bolt hole. The way I made it originally didn't have enough spring to let the hose out the top.

Two completed OEM looking nylon lines. The part numbers I used are: Dorman 800-084: 5/16 QC to 3/8 barb 800-093 same as above but 90 deg 800-086 3/8 QC to 3/8 Barb 800-072 25 feet of 3/8 nylon line I think I bought enough stuff to make the entire fuel system (Not yet done) for about $75. Not bad I found that if i heated up one side of the nylon with the heat gun carefully, gently sandwiched it in-between vice jaws, I could bend it without kinking.

I have more room on the drivers side of the trans tunnel for running the fuel line away from the exhaust, so I dropped the lines down that side of the tank. 2 slits in that foam gas tank seal, and some corrugated split loom should keep it protected. The rubber undercoating was cut away, then I put 2 riv nuts in for the OEM Miata fuel filter holster.

The Chev filter happens to be just about the right size for the miata bracket which is a lot nicer. I just sandwiched the grounding strap in there to keep the filter from building up static since it has a foam insulating sleeve on it. All I need to do is find a male 3/8 QC to 3/8 barb fitting to make the final fuel line to head up front. On a side note, the gas tank is the first thing to go back in the car that doesn't have to come back out again!

The grotty ass brake calipers had been sitting on the floor all covered in grime since the day they came off the car, so I took a few hours to strip them down, clean, and paint them with some silver barbecue grill paint. Red would match the MSM's theme, but it seemed too loud. Silver is fine.

After the gas tank whent back in, I put the rear sub frame back and measured everything needed to get a driveshaft made. It's kind of a weird setup since the AR5 from the Slingshot doesn't have a slip yoke.

Yes that elbow in the vent setup is a 1/2" PVC 90. I turned some pipe down into barbs that fit nicely into the hoses that came off the car.

All the gas tank emissions stuff is gone, so I repurposed this air filter canister and breather snorkel thing that originally had a bunch of solenoids, charcoal canisters and junk attached to it. I tested the gas tank vent (The big one, not the tiny vent that is connected to the filler cap) and it has a rollover valve already built into the tank along with some nice baffles. There is no need for an external rollover valve or anything, just a way to let air in and out of the tank.

I know it doesn't really matter if you just leave the regulator hole wide open to just splash back in, but I had a minute to fab up something, so why not.

Made a few press tools on the lathe. but most bushings were able to be pressed in using random cutoffs and scrap. Kinda tricky to get a setup rigid enough to get those bastards in.

3 hours of work and lots of dish soap later, they are all in. I also got to test to see if the driveshaft shop stage 1 Ford 8.8 to Miata axles fit. They do!

I couldn't seem to find a clutch master cylinder with a large enough bore to work with the short Miata pedal and the Chev Colorado slave that also had an internal reservoir, so I had to go with this .81" Wilwood and my own adapter. I made this Delrin adapter to use the factory reservoir and grommet.

I immediately broke the Delrin adapter because I can't do simple addition and made the CB only about 10 thou shallower than the whole piece. 2 hours on the lathe wasted. I remade it out of 2011-T3 alum. I love free machining aluminum. Any easy to machine material actually.

I also had to make a sealing washer to seal the adapter to the cylinder, and, of course, the only Teflon I had was like 2.5 inch diameter. Luckily cutting PTFE is a dream with a sharp HSS tool.

Here it is. I just copied the basic design that V8 roadsters uses. It's just a piece of 1/4" plate with a pair of threaded holes for the master, and 2 at a weird angle for the clutch pedal studs that poke through the firewall. The latter aren't at 45 degrees like you'd expect. I had to remake the plate after assuming the were.

You know how shit always gets into the miata AC system because it doesn't have a cabin air filter? well I tore out the snorkel the blower receives that dirty leaf-filled air.

I replaced that snorkel with a solid piece of steel because its a god damn convertible and doesn't need an outside air vent.

Those swaybar brackets I made a few weeks ago can now be welded on since I can put the control arms back in enough to measure where the end links go. This BMW bar fits so perfectly under the crank pulley and AC. Thank you based BMW.

The motor was out, so I took the time to finish putting it back together. I used an M6x1 Mazda Miata bolt to hold the oil pickup tube in place to appease the Mazda gods.

This is a little bunny that somehow got in the garage. I wanted nothing more than to keep him, but wild babbits don't belong inside. He was so soft though.

This one took some serious thought. I bought a LUK 04-905 LS7 clutch set for this Miata because it is only $245 for the Clutch, PP, and flywheel that I know will hold the power and be super easy to drive on the street.

A friend of mine pointed out that I'd never know what my timing is unless I made a pointer that could be used with a timing light. All I did for this was drill and tap 2 holes in my alternator bracket and bend a strip of .062 nickel into this shape. I wouldn't recommend using commercially pure nickel metal for stuff, but I had it laying around.

After a little cleaning, a new rear main seal, a few holes in the bell housing, a new oil pan gasket, and 2 -3AN lines hooked up to the clutch slave, the motor is all back together. It still needs the pushrods and rockers, but those are in storage until its ready to start.

I seamsealed all the welds on the tunnel and cleaned the engine bay as best as possible. Took about 10 hours to clean the bay and most of the interior with a wire brush and kerosene. It still needs a final cleaning with a solvent, but I've run out of time for this weekend.

Anyway, that same friend recommended welding V-bands to my headers instead of using the 3 bolt flanges. He also suggested keeping my heat under control and using the thinnest filler possible to avoid warping. Doing that and using my jig of a spare V band welded to a piece of steel kept the warping down to only about .005"!

I'm done wit the front subframe, so I went ahead and painted it. This is the color I plan to paint my engine bay, and I'm pretty happy with it.

The downside of the LS7 clutch? It weighs damn near 60 pounds!!!!!! The flywheel weighs 26.5 LBS, The PP weighs 24, and the clutch itself weighs 6.6. I have this same setup on my 3,400 pound corvette C5, and it really does work a trick for the price. I might eventually get a lighter setup, but this will do for now.

After paint. You can see that air filter down there with the shop vac hood behind it. It actually worked pretty well with that and a small fan to inflate my tent. A proper mask with the correct filters is extremely helpful here.

This stuff has some gravity, but I think a couple pounds is worth adding to the car to make it a nicer place to be. I use the Noico brand rubber because it works the same as the expensive brands. It makes a night and day difference when tapping on the door as far as ringing and echo.

I took the doors apart to measure for speakers and while I was in there, I cleaned off the old butyl goop, threw the vapor barriers away and put 80 thou thick Butyl mat on the outer door skins. I will remake the vapor barrier out of the same rubber for even more noise reduction.
