I just want to make sure since this is one ecu almost NO ONE mentions when doing a b20 swap...

This is going into my 93 Civic CX. I just need any NON-VTEC OBD-1 ECU right? So I can use a Stock DX ECU or more preferably, an ecu from an Non-vtec OBD-1 Integra RS/LS/GS right?

Any differences between the PR4 (92-93 Integras), P74 (94 Integra), or P75 (95 Integra)???
Which is the best to run for best performance with a JDM B20B in a 93 Civic?

Correct, you will need an OBDI nonVTEC ECU. Many people use the P06 Civic DX, PR4 Integra and P74/75 Integra ECU's to run B18A/B and B20B/Z motors. All of these will plug into the cabin harness of an OBDI Civic and run the motors. There are only slight differences in these ECU's.
