I've chosen the K20Z3 because it's very hard to find a K20A around here. So, it would be harder to find a 02-04 RSX harness. Yet I prefer to look for a 02-04 RSX harness diagram to build my own.

I'm planning to build my own Ariel Atom replica with some modifications in chassis and suspension. I'm going to use a K20Z3 engine from a 06-11 Civic Si with 6-speed manual transmission and a K-Pro as well and sure, I have to do the whole chassis wiring and do some modifications to the engine.

So, you think it's better to get a VTEC ECU for my S300? I want to be able to run all of B-Series engines with my S300.

Thanks again
The part number is 37820-P29-T00

Thanks
I have a P29 ECU too. So, What about this ECU? Is it compatible with S300 or not? Does it run a VTEC engine with/without S300 or not? Is it possible to convert it to VTEC or not?

Hi
I have an ECU with this part number: 37820-P72-941
I think it's OBD-I but I'm not sure. It has 4 connectors. It seems to be an auto ECU but I'm not sure about this too! :)
So, my question is: Does it accept S300 or not?
