all motor I would go 86mm bore on a sleeved B18C. also smog is goin to be tough and a CRX is a very tight engine bay....I would look for a 92-95 hatch and make your life easy. mid 11 second daily driver turbos are not unheard of on the east coast and I believe their are a few on the west as well. if you are goin turbo and a street car I wouldn't go over 9.5:1....a good engine builder told me straight up that compression has nothin to do with turbo spool
