just from the top of my head, im pretty sure im 99.5% accurate on it all.

1990-1993 all SOHC non vtec

all Lx's came with rear drums, no sun roof, f22a1 motor which is 125hp cloth interior
Ex's came with rear discs, sun roof, f22a6 135hp? cloth interior/ same maybe leather?
Dx, came with drums, no cruise control, no sun roof f22a1 cloth interior
i dont remember what the SE came with, but had leather. and the f22a1 i believe..just an upgraded LX.

some very with power locks, power windows.
all seats and interior design is the same.
95-?
some come with f22b(ex?),SOHC vtec motors and some V6 in the EX models..
interior and other still the same with the 5th gen.
