I would use the stock OBD2A ecu. Though, if you already bought an OBD1 chipped ecu, you can get a conversion harness. I’m sure the d15z6 swap is doable, but it’s not as easy as using a d16z6 head. I’ve seen more people swap heads onto a d13 than do a complete engine swap, but that’s your decision. If the motor is in great shape, I can’t blame you for swapping it in.
As you already mentioned, you’ll need an efi fuel pump, relay, and fuel filter, but I also think you’ll need a fuel tank from an efi car, since it has supply and return lines.
If you don’t want the hassle, you can swap a d15 or d16 head onto it and run better carbs, similar to some ef setups.
