Heya

I can pick up a known working 02-04 primary O2 for $100

It's from a base model, though. Is this going to be suitable for running KPro on the 05+. I know I need 02-04 ECU (Type-S ECU if I want reverse lockout), 02-04 O2 sensor and obviously the harness+KPro

So can I use a base primary O2 sensor?

Yes. The 02-04 base and type S primary o2 sensor are interchangable.

among the same lines... does the honda accord 2003-2004 4 cyl Primary O2 Sensor is also compatible with K-Pro??

We have not tested the 02-04 Accord O2 sensor, so do not know if it is the same as the 02-04 RSX sensor.
