Hello all, I live in a county of Pennsylvania that requires annual emissions testing.
I plan to swap an LS in my s4 fc and while I'm sorting out brakes, suspension, interior, etc. (the car has been sitting for 14 years) I'm looking for advice as to what I need/don't need as far as emissions equipment to make this swap legal once I get to prepping the LS for install.
PA offers registration under classic car tags, with that the car would be exempt from emissions testing. The downside of that type of registration is an annual mileage cap, I believe it's 5,000 miles.
From my understanding the inspection process is "visual", meaning that since there is no OBD port the technician will just visually confirm that all the emission related equipment is present.
Now the main question I have, and perhaps those of you that have been through a similar situation can help answer, does the emission equipment like EGR, EVAP, cats, charcoal canister, need to function or does it just need to be installed and appear as though to function?
I would like to register the car with a normal tag so I'm not restricted to annual mileage, also I plan to send the GM ecu out to remove VATS and if necessary remove all emission related functions as well.
