From the TSX forums:
since the RRB and the RBC are newer, they require the use of a Drive-By-Wire throttle body. Since the K20A and other models are not Drive-By-Wire, the throttle bodies do not bolt up. You will need an adapter plate used in conjunction with a K20A throttle body and cable
the adaptor plate is only for non drive-by-wire TBs... so i wont need it for the k24a
thats what i just said up there.
but anyway this mods should be good for you
