Re: f22 manuel to f23 auto swap
To my knowledge, those blocks are the same. Everything should mate right up. You'll probably just need to swap the flywheel over from the manual engine to the auto.
One thing you will need to pay attention to though is the wiring. Make sure that both engines are the same OBD generation. They're probably both OBD2, but you're going to need to be sure.
Since you're keeping the manual tranny, the wiring is pretty simple, as there won't be many wires to account for. Your primary area of concern is whether or not the engine will wire up to your existing ECU and wiring harness. If the wire harness wires up, and you can swap the ECU (or they might be the same anyway) all will work out.
Good list of ECUs here: http://wikitest.pgmfi.org/twiki/bin/vie ... itionCodes
Which F23 engine is it?

It'll be a good swap. The Accord engine is probably OBD2. Since you have the car there, just go and look at the plugs and check the ECU codes. They might even be the same ECU.

yea the f23a1 is an obd2, so that looks like i would have to change out too much, in that case ill just wait to do the h22 swap. well thanks for the help
