If he's not fimiliar with Hondas, he's going to have fun dropping an OBD-II hydrolic transaxle B-series into an OBD-O cable transaxle CRX body.

Can he not just suffice with an easier swap (like an OBD-0 B18A or B16A) for now until he learns more on the subject? Wanting to drop a "Type R" motor into anything is a red flag (noob alert!) for me. He probably doesn't realize there are three readily availible "Type R" engines (B16B JDM Civic Type R, B18C JDM Integra Type R, and B18C5 USDM Integra Type R) each one different.
