I know with civics OB1 is from 92-95 but your Delsol has the same engine as the Civic SI Im guessing its OB1 just because of the year but they did use that engine in the later civics 96+ so it may be OB2
give 703-440-8705 a call and ask them if they know thats NU Image in VA
worse comes to worse you will just have to add a few wires the hardest thing about your swap is when you get it in and find a few sensers broke... pain in the butt stuff
your engine "should" come with the engine mounts still on it if not you will need a set of GSR or Delsol VTec engine mounts Im pretty sure
www.hasport.com sells them
and if you do need to add wires for OB2 Im also pretty sure hasport sells a wiring kit for it or pick up the old SCCM that had the wire diagram
good luck on the swap if worse comes to worse you can just give me the engine I could use a backup trans/engine =)
