Hi, I have a quick question. Noobish. I was sorta thinking of swapping an RB25 into my s13, I live in IL so we have no visual testing. I was wondering how good my chances of passing emissions are with a stock, or close to stock RB25 with a type of fuel controller and high flow CAT.

BTW: if I dont keep it stock the parts list will be something like this.... GReddy Intake ManifoldFront Mount Intercooler APEX'i AVC-R Digital Electronic Boost ControllerAPEX'i S-AFCII Fuel Computer 3" exhaust with CATApexi filterect.dyno Tuning

well in NC, i have a 95 wit a 25 and i passed, but no smog was needed with the OBD 1 car...basically here, if ur horn, lights, and tires are good, and no check engine light is on...ur good, but i also had a friend do my state inspection...but i think if it would have been inspected by someone else...i would have failed due to tires, but he gave me 2 that we mounted the next day that were deemed "safe"!!

Anyone else think I can? I hear its easier to pass with an obd1 car with an AFC then with an obd2 car. I will probably add whats listed above, I wont be adding anything like aggressive cams or injector upgrades, I'm keeping this really lightly modded.

I've heard of people passing and since it wont be modded a lot I think with a CAT and proper tune I can pass. Idle test at least, idk. Do you think I can pass or do you have like stories of how you passed or tips?

In California, any engine can pass emissions, even RB engines can meet and exceed the required emissions mandates.
