You may kill two birds w/ the t-stat problem. If the t-stat isn't opening properly, the hot coolant may not be reaching the thermosensor at the bottom of the rad that activates the fan. This happened to my '85 CRX a few weeks ago. The car would run hot, but the fan still would not come on. The bottom hose was always cold vs. the scalding hot top hose, due to a faulty t-stat. If the coolant won't reach the thermosensor, the fan doesn't receive the signal to activate. This may not be your problem, but it's the place to start, and sounds convincingly like my car's symptoms.
PS -- Do you have that grocery list of bits to complete a VX swap? I made sure not to buy anything else until you told me what to get. Someone should sticky the list so later Z1 swappers won't have to hassle you for info like I do
I finally sourced a VX parts car 70 mi from my house that I may get everything I need from minus a converted harness and Helms manual. Thanks again and congratulations! Mak
