When I do so, any spare AC/7A parts are yours for the picking if you like.
I'll even be in Seattle come late August... nothing beats free parts, delivered free!
Thanks, I'll definitely take you up on that. So far, I think I just need the lines that run to/from the compressor (to the evaporator and dryer). I've already got the compressor and mount.

For reference, you need to use the return fuel line from the 20v as the 20v has a larger fitting. 20v screws right into the 20v FPR. The inlet fuel pressure line fits just fine, once you remove the banjo adapter.

Injectors (Bosch 0280155759) and adapters installed. $88 for a set of 5 that were cleaned/tested and come with a 5yr warranty!
Mounted in the fuel rail. I think I want to find some clips to hold the injector adapters into the fuel rail. I'm guessing that with the car N/A, the fuel rail bolts will be plenty, but it's just an extra safety factor. I think most people don't even use the lower injector clips like i did.
20v brake booster line didn't reach the 20v intake port and the 20v didn't come with a vacuum booster, so....found one off a 1.8T New Beetle at the junkyard that worked perfect! Also got some new OEM-style cloth braided vacuum hose.
Got the breaker and terminal lugs to build my battery cables, still waiting on the 1/0 SGX cable to arrive. Also ordered some 4AWG SGT cable for smaller stuff.
Started work on the front coilovers and got the lower perch off. The fronts need new Koni struts, which won't arrive in time for Audi Expo so I'm going to reassemble with the stock struts for now.

Hoping to. I've got the 20v CC pump installed and it's pretty much identical to the 20v pump I also have, minus the mounting due to the brake booster. Should work!

Well the marathon to get the car ready for Audi Expo is over and it won't be there :( Attempted to start it tonight, but it looks like I've still got some wiring to troubleshoot as it's not triggering the fuel pump. The final nail in the coffin came when I jumpered the fuel pump relay and found a leaking fuel line. I won't be able to get a replacement or build one before next Saturday. The 20v fuel inlet line is leaking at the crimp going to the fuel rail and it's also not sealing correctly with the 20v body fuel line.
So some updates on the progress thus far...
A thread restorer kit has been invaluable for this build. The car is super clean since it's been a PNW car it's entire life, but there's still some crust on nuts/bolts so this tool has been great for cleaning them up. IMG_20150610_193656628 by Vex Art, on Flickr
NAPA sent me the wrong driver's side axle so only the passenger was replaced. Going to order a rebuild kit for the driver side since it seems to be in pretty good shape minus the boots.

Got a 7A throttle cable since the 20v was too long. Sadly, the firewall and gas pedal connections of the B3 chassis are completely different from B2. So, I modified the 7A cable with the B2 firewall and gas pedal connections. Use some thin aluminum tubing to crimp the two together; tested it with quite a bit of weight and it held.

Cable was still a little long (I think I need to shorten it on the pedal side), but for the time being I flipped the intake bracket and it works great: IMG_20150613_185123077 by Vex Art, on Flickr
Wow Super clean and great work. Love that intake , i didnt think that "Engine Cover" could look that cool.

Spent the last few weeks waiting on getting the correct adapter for the fuel line. Ordered the wrong one, then got sent the wrong one twice despite ordering the correct one, finally have the correct one on the way.
In the mean time I threw the fuel line on with a crush washer and wrong flare adapter and installed the 7A fuel pump relay and it fired right up.
Nice! A BBQ car finished early. Can't wait to see it

Alright, finally made some progress! Was out of town for work for a few weeks, then some vacation, bought an UrS6 Avant, and a few other things. Countdown is on to BBQ '15....
Tachomter works. Used the tach signal from the 7A ecu, with a 220 Ohm voltage divider.

Converted the gauges to LED. Lots of people haven't had success at this, but I think I figured out a selection that works great. Everything was purchased from superbrightleds.com I'll post up a DIY with all the details.
Protizmo AILD-1 created by a fellow Porsche enthusiast on Rennlist. This is a high side LED PWD dimmer that auto learns the rheostat. Most of the current PWM dimmers employ a low-side driver that doesn't work with a common ground circuit like a car. To use these dimmers, you'd have to wire a dedicated circuit just for the LED's. This is the only high-side PWM dimmer I've found that allows you to use the OEM rheostat.
I built a simple wiring harness for it that plugs into the rheostat. Going to make a video of the dimming, but haven't yet.
Messed around with fitting some Porsche Cup 1 17x7.5 for future reference. I won't be running these at BBQ. Looks like they'll clear the steering arm and fender.
Those rims will look awesome on the GT. Don't forget to clean up the inside of the lips. Looks like there is a lot of gunk buildup.

Some Napa stores with paint centers do custom mix spray cans. I bought off the shelf colors that I kinda blended to match since my paint varies stages of yellowing depending where on the car. Best bet would be to bring in a panel for them to match.

T-minus 4 weeks until I leave for BBQ '15. Want at least a week of daily driving to make sure it's ready, so really t-minus 3 weeks.
New tires are on the way for the TSW Hock's, 205/45R16 BFG g-Force Sport Comp-2.
Other progress from this weekend:
-Aux gauges hooked up and working
-Dash warning lights mostly hooked up, not sure if I quite have the oil pressure buzzer/bulb circuit warning. Also need to figure out the CEL wiring. Parking brake, brake fluid, and coolant level lights are all functionging.
-Windshield wipers and washer are working.
-Windows fixed, faulty switches found AFTER I pulled the drivers side assembly to test it. Thankfully I had some spare good switches around.
-ECU mounted in the glovebox, didn't have enough length to run it over to the far side like the 20v ECU. Glovebox will have to do for now.
Still to do:
-Cleaup wiring, install drivers side lower dash
-Fill/flush powersteering
-Bleed clutch master/slave/brakes
-Fab up exhaust
-Hook up shifter
-Uninstall front suspension to install new Konis
-Uninstall/reinstall rear Konis to adjust them since I don't know what they're currently at
-Fill cooling system, warm up, check for leaks
-Mount front bumper
-Wire up and mount H1/H4 headlights
-Mount new tires when they get here later this week. Cleanup the wheels too; sadly won't have time to powdercoat them.
-Test drive and hope for the best!
-Get an alignment.
