i could not find the information via keyword searches or the reference materials forum. i have an LS/VTEC hybrid in a 92 Civic Si. i want to know from which integra my B18A1 came from?; it's either from the 90-91 GS/RS/LS or the 92-93 GS/RS/LS. the same thing with my VTEC header: where did it come from and how can i tell? any sticker reference?
