The dash is fully flocked, and drying, seems to take 48 hours to fully set. The vintage air unit is mocked in place, one bracket welded in, one bracket finished just not welded, and one more to go.



Dashboard & flocking. The flocking parts are hard to get a quality photo of them, they actually seem to absorb most of the light.

Work progressing on the ac unit, running a little behind schedule at this point.

Finished the vintage air system.  The vintage air only has the heater running, as no ac will be installed until summer. I am very impressed with the system, easy to wire, not to hard to install, and puts out a fair amount of airflow for its size. Just need a cold day to test it, cause apparently cali is undergoing a heat wave again...ugh

Installed a fan shroud, I dont know why previous me did not already install one. Apparently I was a cheap skate when doing the cooling system. Anyways its a Z cardepot fan shroud, listed for 12inch fans. I honestly already have 10 inch fans, and they cool my  little sr20 quite well. Luckily, the 10 inch fans fit the shroud, the fan itself is smaller then the hole(think a 12" fan would fit perfect) yet the outside covers the hole and has plenty of edge for support(they fit which is what I care about).  The shroud itself is very nice, and for the price, hard to beat. Still have to drive her around and see how this changes my temps.

R&R the turbo to fix a broken stud.

Welded the divider in the exhaust turbo outlet.

Pressure tested the system and found a boost leak on the intercooler where the guy welded the new outlet. Going to have to send it out for repair.

Installed a AFR gauge(no pics)

Took her for a test drive and snapped the u-joint on the driveshaft. Warm days + sticky tires = all bad

Sadly the slip yoke was trashed when the driveshaft u-joint snapped. Luckily my local diff shop had all the parts in stock and ready to go. The driveshaft is now fixed and back in the car.
My brakes have been rubbish on this car since day one. Who would have guessed that 40 year old calipers and wheel cylinders would be junk? I mean common, they just are 40 years old. Bigger brakes are planned for the future, but just not in the budget right now. So in the mean time, some new stock reproduction brake parts were ordered. Ended up picking up some A1 cardone calipers for 25 each and some rear wheel cylinders for 27 each. The rear pads were junk so replaced those for 17, new springs for 9, and turned the drums for 15 each. The front pads and rotors were still prime, so those were salvaged. Found one of the rear cylinders was frozen and the other one was clogged. For less then 200 bucks the car now stops fairly well, has great pedal travel and pressure. Now that the car can stop, its time for more power :D

Competition hood scoop is installed and the intercooler can finally vent properly. Still needs sanding and paint, but this will do for now. The installation was pretty straight forward, however the supplied nuts are a pain in the you know what.
