I just recently bought a 91 civic hatch with a b15b1 5 speed, the motors really weak kinda on its last leg, burns oil bad, and im pretty sure its about to drop a valve. So i was wandering what kind of swaps i could do fairly easily for this car. I know cars well but dont know alot about hondas, as far as technical junk. Just wanted to get some ideas for what would be most cost efficient as well as adding some power, without having to switch over my obd system or my transmission, if even possible. I know i will have to do the mpfi swap for sure unless i just put another d15 back in it and i dont wanna do that. Just would like to know what my options are and what all i would have to do for some different swaps.
