98Coupe

hey guys, just picked up a 89 civic ef sedan, lookin to slam it and do swap, i was just wanting to throw a sohc vtec head on the d15 bottom end for now, but..... it does not have injectors it is throttle body injection. i was wondering what car is most common to take a wiring harness out to put in that car to give me some power options. i am use to the ek civics its all ive owned so i dont know much about the old school civics
