I have a 1988 crx with the dual point fuel injection. I have put a chikara header and a fidanza flywheel, but I am looking to get a little more power out of it. I have access to a 88-91 (not sure exactly what year) crx with the multi port fuel injection. the four injector setup, and I would like to do the swap but I need to know what it takes to do it. Do I have to swap the computer, how do I hook the injectors up since the stock wiring harness was not made for them, I just am totally lost. I would appreciate and and all advice/help.
Thank you
