Getting close, thanks for asking:
1) Physical wiring of engine: Done except for dash. So far, out of the 120+ connections I made, my extensive design work in Excel paid off and the harness was exactly correct except for the throttle body which was reversed (an easy 1-minute fix). The dash is easy since it's just power + CAN and the wires are already run to the dash. It will be a Motec D175. Beyond that, I'm just fixing a few minor things like getting a couple switches to properly work. The rear wheel speed sensors don't seem to be compatible with the ECU either, but all this doesn't prevent an engine start.
2) ECU config: Done to get the car started except for things like traction control since the speed sensors aren't cooperating yet. I'll need to fully calibrate a few more stock temperature sensor values, but they're close enough to run the engine initially. I also did the math to get the injector flow rates to a good enough spot. It's complicated because injectors don't follow the theoretical flow rates as their input pressure in the fuel rail varies. You always know the the 3 bar rate from the manufacturer (453 cc/min in my case), but for stock injectors it's hard to find their calibration values. All injectors have some variance off the theoretical rate as pressure changes. I may need to send one in to be tested later to get exact values.
3) Sent the ECU back to AEM today for a little rework since there were a few board changes. I have a relatively early AEM Infinity, so that's why.
4) Converting the rear transmission mount from aluminum to steel for piece of mind. Getting part back next week.
5) Seats: bit the bullet and got Tillett B4's. Love 'em. IMO, they are the best option if you want to make sure a 6' 2" passenger has their head fully inside the roll bar.
6) Alignment: getting a basic alignment done in my garage.
7) ISIS wiring: need to finish up headlight and front harness install. No biggie.
8) Fender liner install: postponed except the rear ones on the center section, which is done.
9) Windshield: waiting until last minute to install
10) Seat belts: waiting, but think I found a good cheap supplier at SEMA. I'm doing a 5-pt harness and am still working through the legal issues of getting CHP approval or if it doesn't matter.
11) Interior: what's that? Punting on it until after car is on the road.
12) Headers: Fully custom. This was a TON of work, but really interesting. I managed to find the right flanges from SPD Exhaust and then bought the pieces to build my own headers and exhaust. The fitment is very tight, so accuracy is key. The angles are all very complicated, since most of the time they go in 2 directions. I just tack welded them and then had them professionally finished. After that, ceramic coating.
That's the top-of-my-head list. I'm sure there's more. I'll probably wait until the new year to start the car, but it's basically all there ready to go. If I took a week off work, I'd have a running car.
