i got my motor from
Import Auto Salvage. Really nice guys there (B-Fast, ask for Randy). I got my B18B1 1994 Acura LS motor with transmission, shift linkage, exhaust manifold (no B-pipe, though, so I had to get a header.... which I would recommend anyhow), alternator, starter, ECU, all wiring for $2K USD.
They are in North Carolina, only 3 hours from where I live, but I'm sure they'll ship. You should call them (toll free) and ask what kinda stuff they have. My only problem was they were sketchy on giving directions to their own place (seemingly just totally unaware
of their surroundings) and they didn't give me the B-pipe (a.k.a. "down pipe".... from the exhaust manifold to the catalytic converter). Be sure to budget for exhaust, cold air intake (the $200 kind), exhaust (2¼ pipe, tune-able muffler, and high-flow catalytic converter, IMHO), new ground wires, new spark plugs, new O2 sensor..... that's with pretty much most of the swaps, so I've heard.
Hope I'm not too off the mark, here.
