Don't Try This At Home: How Could Anyone Resist a Subaru XT Turbo Digital Dash?

don t try this at home how could anyone resist a subaru xt turbo digital dash

After I photographed today’s Junkyard Find in a Colorado self-service wrecking yard, I agonized over that digital instrument cluster. I have this crazy idea that I can hack old digital instrument clusters and operate them with an Arduino microcontroller, so that I can have a display on my office wall to go with my collection of weird diecast toy cars. It started out innocently enough, with this 1983 Mitsubishi Cordia cluster, and then I got the digital cluster out of a 50th Anniversary Nissan 300ZX. Once you have two 1980s Japanese digital dashes, you have a ~~problem~~ collection, right? That was my logic when I bought the digital dash out of this 1984 Toyota Cressida. Even though I’m getting too ambitious with this Arduino-ized-digital-dash project, I felt I had no choice but to go back the next day and grab the XT Turbo’s cluster. So I did.

Someone had already torn up the driver’s-side door-latch mechanism, so I had to climb in through the passenger side and dismantle the latches enough to open the driver’s door.

That’s when I noticed this odd “Speed Alarm” feature, which used a key switch to lock the speed alarm in and out. Oh, Subaru, when did you lose your weirdness?

The instrument cluster in the XT moves up and down with the tilt wheel, which adds immense complexity but is totally worth it for the coolness. It took me quite a while to figure out how to detach the cluster from this Rube Goldberg rig.

Toyotas and Hondas of this era are ridiculously easy when it comes to this kind of job; you can yank an 80s Civic or Corolla cluster in about 25 seconds with just a screwdriver. Subaru had a different philosophy, and so I started removing every 10mm and 12mm fastener I could find.

There’s a hinged bezel above the cluster that resisted all attempts to release the cluster (I could have just smashed the hell out of everything in the way, but I do my best to leave all the parts I don’t want in usable condition for the next parts shopper), and the connectors on the dash harness were fiendishly inaccessible and frozen solid (Subaru went with a much cheaper electrical-parts supplier than did Honda, Toyota, or even Mitsubishi). In the 35-degree weather of a November morning in Denver, my hands took a real beating during the cluster-removal process.

Leaking a little of the red stuff is no big deal, however, when your struggles end with a beautiful 1980s Japanese digital cluster for your collection.

While I was shopping, I also picked up a nice Weber DGV 32/36 carburetor from a car with a strange-yet-familiar engine swap. More on that in a future Junkyard Find!

Weber carbs ... I still remember trying to tune a 40 DCOE. A glorious carb but I never did get it running quite right!

  It's a carb. One can only make it "right" if it runs in a static environment indoors - as a generator engine, and even then they still aren't nearly as efficient as mechanical FI. The second temp, humidity, baro pressure, engine temp, throttle-position, or anything else changes, a carb ain't "right" no more. Perhaps in the ballpark if you work really hard, but never even close to optimal. Carbs are for paperweights, or melting down into intake runners. They had no legit car use post 1973 save that they were cheap because the tooling was amortized. The McD's of fuel delivery..

I think the early 90's maxima had one of the best digital dashboard http://www.youtube.com/watch?v=6zS92Y1mixo&feature=youtube_gdata_player

EBFlex No loss. Ford hasn't had a nice looking vehicle in a very long time.
FreedMike Makes perfect sense. Petroleum companies are the ones who have the most to lose from people switching to EVs. Every one sold is a car they don't get to sell fuel for anymore. Might as well cater to those customers too. At some point, petroleum companies would be wise to make the swtich from selling gas to selling ENERGY, and one of those energies could be electricity. Good business is where you find it, guys.
Golden2husky 2014 Vette, just front tires so far. Acura TL is a recent acquisition so no expenses yet though the passenger window reverses all the time for no reason. 2002 Buick was mostly trouble free until its 21st birthday. Last year brought five repairs, three of which were window regulator issues. I just had a tie rod separation due to an inproper wheel alignment that had too few threads in the outer tie rod end. Good thing that happened at low speed. No fun when you can't steer....
JK Savoy Blue is a thing, but Sestriere White? Sestriere is a ski town near Turin, so I guess it meant to conjure up thoughts of snow. Pretty car. I hope Pininfarina has success. The industry in and around Turin has taken a big hit and is a shadow of its former self.
