Want New Engine!

Hey all, i have a 94 accord lx with a f22b2 engine in it. Im wanting a f22b1, is it a simple changeover? and where would be the best place to find one? Thanks

Junkyard, ebay, local. Ask around i got my engine for 500. You can use the stock trans, axles, motor mounts only thing you would need is the ecu and engine.
