Hey so its been awhile since i posted but im back, i finally found out my number 4 piston was toast and well the rest werent in that great of shape. i opted to do the f23/h23 hybrid, so i pulled the motor and have been doing my research. anyways, ive got everything i need except the f23 block that i need. i need to know if i can use the f22 harness with the h23a1 head, on the bottom end im not worried because im switching out all the ob11 sensors for my originals. and then since im not vtec i need to know what ecu i can use? i know im using hondata s200 because it and knowledge on it are readily available to me. any insight? btw any one in or around utah with a f23 block fs let me know!
