1991 Si motor in a 93 hatch cx

I was wondering if I could put a 91 si motor into my 93 cx hatch? What all would I need and how hard would it be? Also, would it be worth it? Any help is appreciated:bandit:

Well you are going to have to do a hydro to cable tranny swap. Are you talking the 88-91 CRX/Civic Si motor? If your looking at that...you might as well look at the D16Z6 Si/EX motor. They are probably going to be the same price.
