Hey i am looking into doing a 65 or 75 shot onto my H22A. (dry) Has anyone here done it? What plugs did you use? what A/F controller did you use and did you retard the ignition? If so by how much? what are all the upgrades that you did to make it work? I am looking into doing the fuel pump, i don't know if i need to do injectors or the rail right now. Than the controller and ignition timing. i have a MSD 6AL ignition but it does not support timing retard or advancing from what i was told. Any help would be great.
