Well new mounts are a good idea, whether you need them or not. A b16a has a lot more power than your old engine, and replacing a mount once the engine is already in is a real pain.

I believe you just need the mounts for the same year Integra.


As for converting to OBD 1 you only need to do this if you get an OBD I B16a (ECU, some sensors etc are differnt). But if you find a B16a with an OOBD II ECU then there is no need to do the conversion.
However there are not yet large numbers of the later OBD II engine coming out of Japan yet.
