i have a 1993 honda civic hatchback with a 1994 b18c1 gsr engine. i am planning to put a/c in my car. does the a/c units or parts for a honda civic wll work on my gsr engine? if not, any idea how much its going to cost me to have installed?

 

if you have a complete b18c motor, then get a a/c unti for that engine.
check the fole sale forum for prices, and install it yourself.

 

You will need the P72 A/C brackets and compressor. For the rest of it, just use the stock Civic parts.
