i dont know what years were obd1, dohc_accord would know better, but definitely get obd1, will be much easier for wiring and such. let us know how the place racing mounts work out. from my experience with their b series mounts, they blow, but they are the only company who makes mounts for the h22 into the 4th gen. are they bolt in? meaning you will have to do NO cutting and welding?, cause as far as i knew you HAD to cut and weld shit to get that engine in there.
