good luck finding s14sr20 to s14ka compressor adapter plate. i’ve tried to keep my ac when i did my sr swap but ended up just taking it out. sr a/c compressor are different from a ka since you need to swap the sr ac lines in and the whole works to make it work plus refill the system. there is a guy on zilvia making a s14 sr20 to s14 ka compressor adaptor bracket but i’m not sure if he finished it since he’s slacking but he does have s13sr to s14 ka brackets.
good luck if you find out how to make it work w/o replacing the whole compressor and lines let me know
