replacement engine for civic dx

I was wondering which engines I can use to put in my 94 civic dx.

[pdiggitydogg]

Any D, B, H, K series honda engine
as well as anything else from the automotive world, w/ enough funds...

D,B engines would be the easiest, and are most common
H is more work but yields excellent power
K is a lot or wiring work and custom/expensive mounts and yields best power of the honda engines
