Another weekend in the garage- downpipe installed and fits nicely:
Then I plumbed the oil cooler- it's an FC RX7 unit with AN bungs welded to it. I think AN lines are overpriced and kind of silly, but since they're the standard for race car plumbing I figure my chances of being able to borrow fittings during an event are much higher than if I used the metric stuff that RX7 lines normally carry. Annoyingly, I can't actually mount this oil cooler yet since my welder is gone, but this is approximately where it will live.
Then I went to install my new brake master cylinder and... it looks nothing like the picture or either of the master cylinders I have So I said berkeley it, took my old one apart, found the problem (crud was clogging one of the ports to bring fluid in from the reservoir), drilled out the problem, pilfered some seals from the other master cylinder, and slapped it all back together. The brakes bled fine and the pedal has some pressure, so hooray? This car has an alarming amount of firewall flex when you push the brakes, I may need to do something about that in the future.
Then I dumped some fresh gas in it, and tried to start it, but it wasn't starting... unplugged the MAF sensor and capped the BOV and it fired up and ran fine- and now it starts nicely with the MAF plugged back in, too. Weird.
The BOV needed to be plugged because it's open at idle- the setup the car came with had it recirculated back into the intake between the MAF and the compressor, but that hose was destroyed and the easy/robust solution was to replace it with a silicone coupler, which doesn't have a place for the BOV to recirculate into. My solution (for now) is a second BOV (from java during the last GRM secret santa game) in series with the normal one. This works great with no load on the engine, and may actually be fine when driving- it will depend on what the spring pressure on the second BOV is. I realized after I did this that I accidentally made a dual piston BOV.
Sara made door panels (and worked on the RX7) while I was doing all this. Still need to figure out door pulls.
We put the driver's seat and harness back in to make sure everything is happy there. This car has way more headroom than the RX7, although the shifter is very far forward which will take some getting used to.
I made a little aluminum skid plate to protect the fuel lines, brake lines, and filter in front of the left rear wheel- they're exposed until they go into a conduit type thing on the bottom of the car. The front of the plate is flush to the floor and bolted, the rear just sort of hangs from the subframe since it can move a long way and still do its' job.
The car basically just needs the exhaust finished, the oil cooler mounted, and interior stuff at this point. I hope my welder comes back soon.
