well to tell you the truth im one of those guys who bought a project and paid way too much and a year later i spun a bearing and so i bought all new stuff! honestly i couldn't tell you if i have a typer head or a civic sir2 head! the guy said its got a chipped ecu but its got his chip in it from some shop in jacksonville! the injectors are the same as before it blew up and the ecu hasn't changed either so it's matched up still. i have really no idea what to do but i would like to learn and im so far from ppl who know what to do!
