Pulled the A/C fuse so I can run the defogger without engaging the compressor.

Installed injector kill switch and vacuum gage.

Removed mudflaps & passenger-side mirror.
Installed lawn edging air dam.

Found some more aerodynamic hubcaps from a 1986 subaru.

Removed clutching radiator fan, still have the electric fan next to it.

Pulled the power steering pump, drained & capped the lines - way less steering effort than engine-off coasting with the pump installed!

Added a 100k stereo potentiometer in parallel with the coolant temp sensor to reduce open-loop cold startup enrichment. Upgraded from 1-wire to heated O2 sensor, I think it needed a replacement anyway. Runs way better in the mornings!

Changed the rear diff oil to synthetic, Mobil 1 75w90.

Removed the air dam in preparation for front undertray.

Lower coroplast grill block, faired from the bottom of the bumper, very sleek. Upper grill still open.

New front wheel bearings, seals, & synthetic grease. The car coasts from a stop noticeably quicker on cold mornings! New Brembo rotors, $17 from, can't beat that. New hatch struts & wiper motor, fixed the rear door seals. My car is now smooth, quiet, and functional!
Unplugged the Idle Air Control Valve, which was sticking open. Difficult to keep it from stalling, but it will DFCO down to a low idle, which it wouldn't do with the IACV plugged in.

Removed driver's side mirror and installed interior side mirrors. Driver's side works great, passenger side is not very useful because of the sight lines.

Muffler fell off - WHAT? Lubed-up the IACV (no more heel-toe to prevent stalling!) and added an orifice, a 3/16" hole drilled into a dime, stuffed into the IACV inlet hose. This reduced warm-up idle from 2000RPM to 1100RPM. Added a 400W block heater, found a radiator leak Compression check: 165-170 on all cylinders at 220,000 miles!

Planned Mods: I just picked up a dual range transmission to swap in when I do the clutch. 10-speed, here I come!

An undertray has been on my list for a long time now, I may get around to it soon! Plan to remove the rear halfshafts once new snow stops falling. That way I won't be spinning the rear diff & driveshaft.
