So i've tried my research with this and there were multiple threads about mini me swaps, d16y7 heads on d15b7 blocks, etc etc.

I can't find a thread anywhere were it talks about having to mate a d16y7 intake manifold on a d15b7 head. To make a long story short, my cousin bought a 96 ek coupe and wants to swap out the blown y7 engine to a d15b7 that I still have laying around and I have no use for it. Is it possible that they will fit, how will the emissions work, and I don't think wiring needs to be redone by any chance because most of the wiring comes from the manifold, and the head right ?

 

Just swap over the Y7 manifold over to the B7 head. It'll bolt right up. Then you'll have all the necessary sensor and etc.
