Nissan changed the specs from the highport intake cam to reduce emissions, so yes that could be attributed to raising the readings from stock specs. I have the highport cam, g20 ecu, cone filter, pacesetter header and I pass with flying colors.

your 200sx is obdII you should tell tem that aand tell them they SHOULDNT be sniffing you on the dyno. Your ecu should be scanned and if your cel is off before you get there you should pass.

What where your results? How high was the NOX? List all your numbers. Failed several times on NOX myself. Every time it was the CAT.

to pass smog in nazi-smog town california, i had to get a new egr valve AND a new cat.

the egr valve at the dealer cost me around ~90 dollars at the dealer i believe...

and the new cat i got restricts my entire exhaust like a beezy

i hate california smog :[

oh yeah try to get a cat welded on, i got my new cat for 100 dollars and helped me pass smog :D
