Quick question on motor interchangability

I'm sorry for such a noobish question (i'm new to nissans), but could I put a 93-97 altima 2.4 into a 93 240sx? Would it just bolt in with the altima mounts? Also, could I use the altima wiring harness and ecu? Or would there have to be some kind of special adaptor kit? Thanks in advance!

no no no no, and no
