thanks for all the info PHiZ, I was hoping you would see this....

I don't have the H22 background, I have a B series and D series background.
That being said, an OBD1 prelude ECU should run fine (P13). There shouldn't really be any auto tranny considerations. IN the civic and tegs, there is no modifications neccesary to run an OBD2 motor off an OBD1 ecu. CKP sensor is the same, and everything else is the same.
Do some more research, I'm sure ppl have done this swap a whole bunch, you'll learn the little tricks, like if I remember correctly on 95-96 prelude chassis, they switched pins A1 and A15 or something to do with fuel pumpery. Sometimes IACV is slightly different between motors, and FITV is sometimes different between auto/manual.
Something also to consider, OBD2 prelude ECUs aren't going to do you much good because of the built in immobilizer function, so you'll need the (key?) that matches the ecu (could be built into the key cylinder in the steering column too, dunno.)
