k24's

the kseries took over as a block that could be bored from 2.0 to 2.6 liters or so i believe, so it encompases both the larger displacement needed for the accords and the smaller displacement needed for the now larger civics and integras (rsx's)

right now the 2 engine coldes are k20 and k24

i believe that the k-series has only been widely fitted into 96+ civics so far, so no dice for you right now, but there have been people who have fitted them into crx's (with parts going beyond the hoodline)
