B20B ECU and wiring on B20A engine

[Ctrl_Alt_Del]

hi..

im going to swap my 4th gen civic 4 doors with b20 series,
but im cant find b20a complete engine, autotrans, wiring, ecu, ect.
can i use b20b ecu and wiring to plug in to b20a auto engine ?

i choose b20 because it has big torque, than b16 and im going to choose for automatic tranny..


in junkyard only available :
- b20b : engine, ecu, wiring, and no transmision
- b20a : engine, auto trans, no ecu, no wiring

i cannot find any b20a wiring and ecu everywhere in town at this time
only available B20B's ecu and wiring.
will it fit normally? (a little remap its ok if needed.)

which is better, going to take b20a engine and trans, with b20b's ecu and wiring,
or just take B20B engine, ecu, wiring, and b20a trans ?

thx before

B20a's aren't swappable into civics. You need a b20b/z. You can use the b20a's valve cover as a jello mold or something.

and how about transmission?
i cannot find any b16/18 autotrans in town
can i use b20a autotrans and install it in to b20b ?
