Most of the accessories and ancillaries will bolt up from b16 to b20... alternator, dizzy, power steering, a/c. Brackets might be different for a/c if I recall... some parts won't... like the intake manifold.
But little details will be off, such as different pulley size on b20 vs b16... the distributor for a b16a runs a different Ignition control module so pre programmed dwell time will not be for the b20... and you may well blow the ICM or coil.
By all means... read up online on the details as almost everything to do with a B swap has been covered online many times over... honda-tech.com or superhonda.com might be able to help with research resource too.
