First off your going to need
1. sr a/c bracket(ka wont work)
2. custom bracket to mount the ka compressor to the sr a/c bracket(not a direct bolt on)
3. or a sr compressor with custom a/c lines
good luck and hope this helps...
there was a guy making the bracket kit on nico or something iirc his name was codyace(sign on name) google it with sr20det "codyace sr20det" should show some stuff...
