I added a fuel pressure sensor so I can log fuel pressure. I bent 3/8 stainless hardline and covered it with DEI insulated heat sleeving. I decided to try compression fitting/AN adapters on both ends of the Hardline.

I used a piston stop to find top dead center and then I marked the dampener with a paint pen.

Some cardboard aided design for my timing pointer. I'm adding this so I can accurately calibrate timing in my tune.

I used a piston stop to find TDC. Rotate clockwise until you find #1’s compression stroke. Pull the rocker arms on #1 and continue until you hit the stop and make a mark, then ccw until you hit it again and make another mark. Half way between them is TDC. I used a measuring tape to find the circumference of the crank pull and divided that by 360 to come up with 1.6mm per degree, then made a few timing marks. This is all so I can properly calibrate my motors timing when I start tuning.

I like to use software to design parts, but resorted to CAD (cardboard) for my timing pointer.

Speaking of mounts and headers and setback plates, this is where you run into clearance issues with running the cooks/V8R longtubes with the Monster Miata subframe. After I moved it back an inch, there is 3/4” of clearance to the front mount. I moved it back a little further than I needed to. If I had it to do over again, I’d countersink all 4 holes in the plate and move it back 5/8” instead of the full 1”.

The V8R headers only gave me at best 1/4” of clearance to the driver's side knock sensor. Someone suggested to move it forward to this position so that's what I did. I had to modify the driver's side mount for clearance.

Installed a starter blanket. Trimmed it to fit better. It's got Velcro but I used some safety wire to really tie it down. Summit Sum-350118-1 You can see my 1” setback plates here.

I drilled and tapped the water pump for -10 AN to NPT fittings.

Here are the heater boxes mocked up with everything fitting. I've finished maybe 80% of the wiring at this point. That mess on the passenger side floor board is the bulk of what I have left to do.

The circled area is where the body harness will come through. I've been working on the Heater core hose tuck in parallel with the wiring. Here is my hose routing from the cowl around to the water pump. Eventually I'll add AC, so I'm making sure to leave room for routing those hoses. The hose fittings are all aeroquip socketless -10 AN and the tube ends are -10 an male - 5/8" tube compression fittings.

The bulkhead fitting one on the left is the return line from the top tube on the heater core. I cut the end of the bulkhead fitting off and welded it to the bottom of the remote fill tank. The one on the right is a 90 degree bulkhead fitting and it goes to the rear port on the water pump. A 120 degree AN fitting would have been a little better than the 90 here. I had the blue ones on hand already... couldn't bring myself to buy more fittings for something that is not normally seen.

So here it is with the stock plastic cover (slightly trimmed) in place.

And here is the part fully welded up and installed. I don't weld aluminum often and its easy to fall out of practice. This part was a huge pain but I'm good with the results. Building a larger/taller tank and putting it on the firewall would have been a more optimized design but I want to keep the firewall clear.

I made up a 3d model of my washer tank, printed out templates, made up a mockup from an old political sign, Traced the templates on a sheet of .090 5052. I cut the aluminum with a jigsaw and cleaned up the cuts on a harbor freight belt sander.

It took some looking but I found a couple of wiring harness specific grommets from Mouser. I installed the larger one for the part of the engine harness that wraps around the bottom of the engine... starter wires, 02 sensor, knock sensors, cam/crank sensors, alternator wiring. I used the OEM engine harness grommet for all the wiring on top of the motor.

2 1/2" Magnaflows and vibrant resononators, the same ones Tom used in his thundrerbolt build.

These are the cutouts i got off of amazon prime. They are very good quality and suprisingly affordable. A great value compared to the common electric ones out there. The OEM's use cutouts very similar to these.

I added in 3" interlocking flex joints. The front half of the x pipe is from pypes, i couldnt make it fit the way i wanted so i cut it in half and made the rear splayed section.

Finished up the exhaust yesterday (still need to weld the tips on but the car is backed into the garage right now) . The tunnel needed a little clearancing, but the cutouts fit.

Not sure what this saw is called but it worked perfectly to rough it in within 1/8" of my cutline. From there, i got it close with the flap wheel, then finished it by hand with a piece of 220.

I'm going with magnaflows but am curious about hooker aerochambers... Maybe next time. I made a cardboard template from the original notch in the bumper cover. Just flipped it over and measured back the same distance from the wheel opening.

Been making good progress on my exhaust despite the onset of summer (hell season) here in florida. Those are dual 3" tubes that I'll connect to the kooks/v8r longtubes with band clamps. I cut a 2 1/2 x pipe in half and made a splayed rear section for it. Those are vibrant resonators. I was able to keep the stock bracing under the diff with the exception of the two side pieces which i need to slightly modify. I intended to run a pair of QTP cutouts but they are too big for this location...

Finished welding up the fan shroud. Everthing including the radiator hoses fit perfect. I love it when a plan comes together.
