Passing emissions has always been an ordeal for me, even when the car was stock and should pass. I am in Connecticut where any vehicle under 25 years old is required to pass the OBD emissions test every 2 years, or they won't let you register the car. I have considered registering the car in a different state, which turned out to be possible but a bit shady. So the next option is get it to pass in CT. As the car normally sits, it has a standalone ecu, no SAP, no cats, and no OEM O2 sensors. So not a chance at passing.
What I was thinking was to get the OEM parts required to make the emissions systems happy, and only run them for the test. Stock ecu, stock pre cat o2's, SAP, and stock injectors. The exhaust did originally have cats, so visually it looks like it has them, and I could just code the stock DME for no cats. Swapping all those parts is quick and easy, however I am still unsure of some things. There are bungs to run both pre-cat o2 sensors, however they would both be reading from all 6 cylinders, instead of bank 1 and 2 separately, which could be an issue. The car also runs a MAP sensor and does not have a stock MAF. The turbo kit came with the maximumpsi MAF but I believe it will not work with the stock ECU without coding for it.
If I could figure those issues out, and just make sure it doesn't see boost with this setup, I think its my best option. I'd like to hear from anyone that has been successful with something like this or even a completely different route.
