V.I.Guy

So i have a 1994 DX coupe, JDM B16a, hydro tranny, PR3 ECU. I bought it this way, and i need some new parts. I have no idea what parts from north american cars can be swapped. Im a mechanic, so i feel a little sheepish about my questions. I do want to replace the following jdm parts with new ones that will work correctly.

I need:
- New Distributor
- New o2 Sensor (one on the car, 4 wire)

i think its a OBD-0 car, but im not sure....any advise is greatly needed :D

Cheers,
Luke
