B16A, gsr cams, CAI, DC 4-2-1 headers, side exhaust 2" piping from header flange, fuel pressure regulator.

I don't want to convert to OBD1 unless I have too...wondering it I lower the fuel pressure if it'll run better. I haven't dynoed it.

 

Obd1 is just better man, I was gonna stick with obd0 as well, but not only you can't use scanners on OBD0 but it will cost as much as converting to obd1 to modify and remove rev limiter and etc, unless you get hook ups.

If you have the money and the patience, I'd go obd1. Better engine and fuel management, can be diagnosed and properly tuned.

Good luck with obd0 tho!
