Since the last update, I replaced the ECU coolant sensor and harness, which unfortunately did not solve my problem. Looks like it's back to Ultimate Z in the near future for more troubleshooting.
Today, I got out of work early thanks to the weather, so I took the opportunity to finish up my other 3 wheels. I don't have any progress pictures, but here's a quick shot of the car with the 'fresh' wheels:
I also picked up this black bushing kit from Ultimate Z when I was there a few days ago, because Coz has been out of stock for the past 3 weeks.
There's going to be a huge tech day(s) sometime in the next week or two. In one session, I'm going to be installing the steering rack, bushing kit, and springs. It should be a formidable challenge, as I've never done any work with springs or steering racks, and only limited work with the Z31's subframe bushings. From what I've heard, the bushing kit is a nightmare to install...I look forward to it
