After the first layer of sound control went down. This stuff is pretty fun to apply actually.

All the layers done. Be prepared to lose plenty of tiny holes you mask up with little pieces of painters tape. Silicone plugs are much better.

I made an adapter plate to move the miata shift boot. I sealed it off with butyl rubber and secured it with rivet nuts that also hold the boot in place.

I needed a place for a washer bottle since I deleted the OG one way back when I re-turbo'd this thing. Yes it just PVC pipe.

And it goes up in the cowling. 3" pvc with a street elbow and the factory pump in a hole on the back. Hood barely fits, but it does. There is thin rubber bumpers on the bottom to keep it from rattling.

I couldn't see a way to use the factory rad support, so I made my own. Later I added L brackets to the front for a Corolla AC condenser to sit on. The bottom C channel of the radiator was lined in dense high temp foam rubber and it sits over those aluminum pads.

Here is that corolla condenser with some brackets made up. They use the factory miata rubbers to isolate it.

I'm just jumping around here, but it all has to be done. The original throttle cable hole was cut out and now has a head in front of it anyway, so I extendo'd the gas pedal lever with barbell shaped piece I made on the lathe so it would line up with the cruise control cable hole. MSM never had cruise anyway so no loss.

Here is the finished radiator shroud, radiator and 2 massive 11" spal fans that are completely sealed to the rad with more rubber foam. Those things are rated for 1300 CFM each at 0 in/hg, and have the amperage to move some serious air. This thing better not overheat, because I have probably 20 hours in just this damn rad and shroud alone.

The AC blend doors were toast and blowing chunks of foam at me when the car was running, so I decided to rebuild those.

I just kinda eye-balled the shroud. It should perform quite well though.

Here is the first door covered with some high density foam. The heater core has to be flipped around so the water ports face the correct way, but that's a whole 'nother project.

Here is the accompanying throttle cable bracket. I had to adjust the gas pedal stop and bend some things, but I have full throttle travel with a stock-ish miata pedal and cable! And I don't have to cut up my corvette's engine covers.

The griffin rad is a bitch to weld to since it has epoxy around all the tube ends for some reason. I just had to keep the heat to a bare minimum. The 4 big mounts are for the radiator shroud. The 2 small ones were a failed top mount design.

This is the AC drier/ pressure switch mounting location. You can see my L brackets for the condenser on the rad support. Also yes that's a bicycle water bottle holder. I mean, if it works...

Mocking up the much beefier radiator top mounts. There are some rubber grommets under there, of course.

It took about 4 hours of cutting, measuring, looking, cutting, shifting, eyeballin, scooting, taping, and closing the hood to get to the point where I was happy with the intake. 11.25 degree cuts out of .080" 3.5" OD aluminum are the specs for those Pies if you want to recreate.

My axles with ABS from V8 Roadsters finally got here after a couple months. I don't know if that delay was on DSS or V8R's side, but whatever, they fit. The coilovers and most of the suspension components are installed now.

While the bumper was off, I decided to stick some Hella Sharptones on either side of where the "mouth" of the bumper cover will be. I didn't want to look like a Subaru with horns visible behind the grille, so these will be hidden to preserve the stock(ish) look.

Here is the final product after I got done welding it all up. There's a little L-Bracket welded to the pipe to keep it from banging around in there when that cam starts hitting.

It's time to actually wire this thing. I pulled the neglected harness back out, and finished labeling everything, and cutting out any wires that are for stuff I don't need. It seriously took like 80 hours from a completely wrapped up harness, to this stage. It's worth it though, because I know where everything is now and what it does.

After stripping it down, the harness goes back in the car for actually wiring stuff up. I also cut all the wires off the main factory fuse box and pulled them all into the passenger foot well where I'll make a false floor with a power distribution hub. I just really didn't like mazdas way of powering things. You can already see my 1/0 power wire coming from the trunk and running along the passenger sill. The ground wire is under the car bolted to the trans, and a bare bit of frame.

I decided the ECU needs to go just to the left of the driver side strut tower brace for clean wiring, ease of maintenance, and ease of assembly. I wanted to put it under the false floor I'm making in the passenger foot well, but it just didn't make sense as far as routing goes. I also stripped the Holley's universal harness apart, because none of the lengths were correct. Also there were a few things I didn't need like MAP, Fuel pressure, etc.

I tried some of those fancy crimp butt connectors with heat shrink built in, but I kinda hate them, and they are way too bulky. I'm just going with the old school method of twisted and soldered. Every joint will be covered in glue-lined heat shrink for waterproofing.

I needed a main fused power distribution block since I don't like the way Mazda did stuff, and here it is. a big ol hunk of Delrin with some threaded holes and Mini ANL fuses all along an aluminum bus bar. I just did the math on how big of a piece of alu I'd need to use and doubled it for safety.

This is the final fuel hose needed. I've been putting it off, but here it is. This is still the same OEM style nylon line, but I have split loom and then a layer of heat shield over it. I still have to pressure test it all, but I really hope that isn't an issue.

Here it is in the car. Main power up top, and secondary shit on that smaller unit. Small one is only rated for 20A per circuit, so nothing too crazy can go on it.

The flat blade type F Body dipstick wasn't working too well, so I made a new one from some aluminum and an old motorcycle clutch cable. I'll have to make a dipper and calibrate it when it's time to add oil.

Last thing I did this weekend was pull a vacuum on the AC lines to see if it holds vac, (it does!) and put the pushrods and rockers in. I probably could have installed the rockers a couple months ago, but I didn't like the idea of those new springs compressed for months on end while the other half weren't.

I've got so much time sunk into this stupid harness, but it it much closer to completion now. I pretty much had to lengthen or shorten every plug on the damn thing.

I've been finishing up little bits like finishing up wiring in the trinary AC switch and the AC clutch itself. This switch acts as a trigger for my second radiator fan for when the pressure in the system gets to a certain point. Of course, if the coolant temp is already at a point where both fans are already on, it won't do anything different.

Here are the 6.5" woofers mounted in BoomMat foam cups and its adapter to fit it in the factory Bose bolt pattern. Note: I did have to trim the plastic surrounding the grill on the inside of the door card since that spacer sticks everything out a little bit further.

I painted the amp mount and added a support bar at the top left to triangulate the whole thing. It was incredibly wobbly with the amps actually mounted to it. All the power wires and speaker wire is ran. Signal wires from the head unit are in the main harness I'm making. I ended up only needing 10AWG copper wire for powering the mono subwoofer amp even though it is rated for about 300 watt RMS output. The run from the battery was just so short.

Moving to the trunk, I made a mount to stack both of my audio amplifiers in the trunk and still retain my space saver spare. This should allow for plenty of ventilation for the amps as well.
