$2018 GRM challenge turbo miata build. with added insanity.
I was going to finally do my revlimiter gauge faces that I ordered the weekend I left to pick up deathtrap from Alabama. However, apparently to set the needles you have to have the car running and driving per the instructions. I’m not there yet, so I settled for tearing down the NB2 cluster. Put the oil pressure gauge through the ultrasonic cleaner to quicken its response, added the resistors to the water temp gauge, kept the bulbs sockets and needles, and scrapped the rest. I honestly don’t remember what gauge faces I ordered, and haven’t opened the box to look.

Spent a lot of time creating a dual relay harness to fire the 55 watt hid low beams and high beams for the NB2 headlight conversion on the NB1 Harness, using this wiring diagram. This was compounded by having a bad headlight relay. The relay would click, but not send voltage. I lost a LOT of diagnostic time there. It was a new failure mode on a relay to me. The HIDs are white in person, by the way

Spent a bunch of time wrapping downpipe, hanging the midpipe (muffler is completely rotten and can’t be saved) tucking wires, securing harnesses and hooking up hoses, etc. making things neat and tidy. The headlight harness isn’t wrapped or secured in these pictures, nor is the intake done. Theres more, but you can see where I’m headed.

You can also see that I started to polish the radiator, and added a maxpeedingrods overflow bottle. Additionally, I bought the yellow mishimotor radiator fan setup. Its half the price of the other colors, and matches the shocks and HID ballasts. I kinda dig the splash of color. And the fans make packaging a lot easier for the charge piping.
Anyway, my ebay special intercooler came in yesterday, so I got a mount fabbed and it hooked up last night. The silicone hoses from flyin miata fell into place, though they have some slight kinking. Don’t know if that’s normal, but ill keep working with them to see if I can minimize it. regardless….

Clean work man. Are you still running the stock ECU with a piggyback or something?
I'd also be interested to hear how those mishimoto fans work for you. I see a lot of people recommend against them but I don't think I've seen first hand or recent feedback on them.
The 3d printed shock adjusters are awesome by the way. Really neat way to solve that problem.

sorry, I have strong feelings towards those fans. They drove me insane trying to solve an issue for a year.

Im not holding my breath on the fans included in the mishimoto setup. They aren't confidence inspiring with a bench test, but thats just based on experience and gut. At least they're a good common size that can be swapped to a spal unit easily if necessary.
The shock adjuster was a 3am sit bolt upright in bed idea. It honestly worked way better than I expected.
Braineack: you have a pretty alpaca(?) And ill do that with the next update and try it, just for you!
