This topic has came up many times before. If you ran 100% of the emission stuff in the sr20det; you can pass SMOG with flying colors. The only thing it wont pass is visuals. The reason why most fail smog in many states is because when a sr20det swap is done to a usdm car, the AIV port is cut and pluged up (hits the steering). The exhaust gas recirculation valve is also removed along the charcoal canister and other such emission equipments.

You would have to make custom AIV valves just to get it all working correctly
