I don't have much experience with EF's but I remember reading that if your car came factory with a 4 speed manual, the hubs need to be replaced with 5-speed versions (inner diameter of where the axel goes through is smaller on those cars). That might only be the older (pre '88 cars) but I'm not positive. The Integra and Civic both use a 4x100 bolt pattern, so if you did use the Integra units (upgrading to get the slightly larger Integra brake assemblies would be beneficial) any wheesl you have now will fit fine.
