Just got k20z3 cams and hondata and have to a3 heads(rsx base) so i have the 8 rockers. my car has already 2.5 exhaust and k&n CAI n filter. i would like to know, if for the swap i´ll need something else? and what hondata setting would u recommend. I saw everybody is talking how good You are, so i just decided to ask U, also I live in Guatemala, hope to get your help, k20 mods here are not that popular.
