Which engines come in a four door?

Call me crazy but I really like 89-91 civic four doors. After I sell my 57 Bug I want to get one, but my question is do they all come with the weak *** dual point injection motors? I want to eventually swap in a d16z6 and that has a crap load of wiring as it is, and I don't really want to do the wiring conversion from dpfi to mpfi on top of that. Wiring scares me. Anyway thanks, also does anyone have one for sale or know of one for sale near Kansas?
Thanks
Tim

The wiring from DPFI to MPFI is stupid easy.
Get a conversion jumper harness from OBD-0 to OBD-1 and you are set to run the P28 ECU for the Z6 -OR- just saty OBD-0, not get the jumper harness, and just use a VAFC to control VTEC activation and bump the fuel maps with the PM6 ECU for the MPFI conversion.

anyway, all the models except the EX came with the DPFI
90/91 EX came withe an A6 MPFI - same motor as the Si hatchback.
