Default '91 Civic dx engine swap

Hi, i realize this has probably been asked alot before, but here goes.
I have a '91 Civic dx, with the stock 1500cc engine.
And im looking to swap it out, either for a b16 or b18 from a gsr.

what is easiest as far as engine mounts go? are either direct fit? or atleast fit with adaptors? (i am able to weld new mounts in if needed, but would rather not if i can get away with it)

Also my transmission is going so im thinking to swap one from the donor car i get the engine out of. will there be complications with that at all?
and as far as wiring/ecu.. what has to be done? or would it be easier to pull the harness and ecu from the donor.

Thanks for any help i can get.

You will NEED a different tranny and ecu and mounts for the swap

for a b series you would need new mounts, shift linkage, integra axles, halfshaft, 90-93 integra throttle cable, a bseries tranny, computer, and you would have to convert you dual pint dx to multi port fuel injection(4 injectors instead of 2). the b16 and gsr motor will both bolt in the same
