Prelude engine swap

I've got a 91 Prelude Si that I recently aquired and I found out that it had a bad engine, which is kinda good and kinda bad to me- good because it means I have the oppurtunity to find a better engine. I'm looking at a 94 non-Vtec engine right now and it's close by and possibly cheap, (I'm def. low on dough), and I just wondered if anyone had info on how to swap the engines. I'm pretty sure it needs no mods but does need a mount kit, and my biggest question is if anyone knows where to get one, and about how much they cost; that'll determine whether I go out and get a new engine.
