I have a VMIC but I found a smaller condenser online and just finished mounting it last night finally. Now I just need a couple lines made. I'm also wondering if there are some kind of quick disconnect fittings just in case it needs to be removed, that way I don't have to evacuate and recharge it every time.
I didn't know you could remove the evaporator with the dash still in, it looks impossible lol.
The evaporator was flushed, but I didn't replace the expansion valve. I searched and searched for one and finally found one that was close, which was listed for an 84 RX-7, but it wasn't exactly the same, and I wasn't sure if I'd do more damage replacing it rather than leaving the old one in there, so I just left it in there for the time being. I'm taking a gamble basically lol. And I'm sad that I didn't replace it now that you're telling me about the small orifice lol.

I completed the project in the spring. I actually have a FMIC, but it is not the typical FMIC that blocks the entire bumper. Its a custom setup that is inset similar to the blitz kit. I ended up reusing all of the stock parts that I pieced together. Finding a condenser was very difficult. I re-bent stock lines, however if I were to do it over again I would have purchased a custom condenser and made custom lines. I ended up charging it with R134a as a method of testing for leaks. I figured if it could hold R134a then it could absolutely hold any of the HC based refrigerants. The R134a lasted through the summer and the pressure just dropped to the point where the compressor wont come on anymore. I have a couple of bottles of ES-12 I might use.
I believe my leak is due to the fact that I used a compressor from a 99-02 engine. The connection points were larger than the 93 so I ended up using over sized o-rings to make up the difference.
I would ABSOLUTELY replace the expansion valve. It is cheap, and it is likely you got dirt stuck in there while flushing. I went through a few aftermarket ones until I found one that worked. If you have a MANA system (denso is different) then this will work:
