what should my high side gauge readings and my low side be when it is properly charged when the engine is running.
how much 134a should be charges after evacuated. I'm only servings after engine swap no new a/c parts added.
thanks

93 civics were R-12. Unless you converted over to R-134a

 

There is a sticker under the hood tells you how much to use from empty, subtract any oil you needed to add, usually 4 oz is about right for a small system. If it's r12 you should flush it out, but it should work ok without if you evacuate it long enough, use 134a compatible oil, I beleive the civics require about 30oz total, check for the a/c plate/sticker though. Preasures depend on the freon type and ambient temps, but usually arround 320psi @2500rpm tops on a hot day with 30-50 on the low side.
