I just put a b18c1 into my auto 94 civic dx. It's pretty easy if you know what your doing. You will have to get a hasport auto to stick mount kit, or order the bracket from Honda. I ordered the bracket from Honda, and I'm going to get it welded tomorrow. You will have some wiring to do also. in the center consol, when you unplug the biggest connector from the A/T shift linkage, you will have to bridge the two ignition wires, I believe they are black/red, and green/black, I'm not sure on the colors though I'll check later on. In that same connector you will have to ground the little green/white wire, if you want your key to come out. The petals went right in for me. the clutch lines need some bending to lign up. but other than that it's just like any other swap.
I just did the swap over the weedend if you have any question fell free to ask.
