How much of a hassle would it be for an obd2b b16a2 out of a 1999 civic si to be swapped into a 91 civic ef? Im asking because someone offered me the full swap with axles hubs ecu full block and all that for 1500.00 if im correct the axles and hubs wont just swap over right?

what parts would be swappable and is it worth the time and money? the car has 30,000 miles on all the parts.
