I'm not an expert, but a honda head i know told me that practically all or most hondas and Acuras are interchangeable with their engine bays.... I have an 87 CRX with a CARB motor and im looking for either F22/23 B16/18 or H22/23 and I have seen these motors, taken measurements and they will slide right into my engine bay, the only thing i have to worry about is motor mounts, the mounting points match up and the mounting poiunt BOLTs match up, but the MOUnt itself is a litter bit bigger, so i need to buy mounts and the axels...... someone else told me i should be able to use my stock wheel assembly but i'll have to question my consideration........ i hope the words i just typed provided a little help... !ITE!
