okay hey all.. i'm looking into getting performance add-ons for my 97 Civic HX. after reading a post about supercharging, i kinda figure I wanna do that someday. but before that, i have to wonder, since there aren't many bolt ons for the HX, what would be best for me to get? parts for the LX, DX, and CX or the EX? I read that the HX has the VTEC-E, while EX is VTEC... but LX DX and CX isn't VTEC at all, I'm reading the engine codes for each car... LX's are D15B, EX's are D16Z7.. but HX is D15Z... so I'm confused whether i should be getting something made for the EX because of the VTEC.. or something for the LX .. etc because the engine code is both starting with D15... its confusing.. any HX'ers wanna help me out here?
