here is another sight with honda engine specs i find a little easier to
navigate http://www.geocities.com/honda_club_egypt/engines.htm , as for
which engine u have, just go by the code on the block, honda usually
has a differant code for every engine even if the block is the same.
the differance in horsepower will be in the head design and fuel
management system, as well the pistons would either be higher or lower
compression, so the engine would have the same displacemnt.
