i currently own a 1990 civic 4dr with a ls swap. my question is my lil bro wants to give me his old gsr full swap and i know i will need cable to hydro conv. and obd conversion harness but my concern is that i currently have the hasport a/c bracket on the ls swap and the a/c works perfectly. if i swap the gsr motor in will i be able to obtain the a/c cuz it will be obd 1 instead of the obd 0 and will the a/c compress fit the the 4-1 type r headers. sorry guys i research this on the net and there not that much info on this subject.
