Now after reading the sticky searching around a little and looking up my own states smog laws I am still realy confused about the whole thing.

I am about to switch from a 305tbi to a 350tpi and im i'm not sure if its going to be legal or not. The tbi had the a.i.r. equipment. However, the tpi doesnt. It has 50 state legal headers instead. The way i've interprete the law it contredicts itself.

As far as i can tell, if i replace my air with 50 state headers that would both me legal and ill-legal = /.

Perhaps im understanding it wrong.

Here's the link
emission laws

 

Scotty:

Here is how I intrepret what the law is trying to say;

If you car came with whatever emissions equipment (AIR, EGR, etc..) on an OEM basis, it needs to be there. However, you can replace the OEM stuff with an equivalent part. This allow you to replace your OEM EGR valve with one from pep boys, autozone, etc..

However, if you are planning an engine swap, you need to retain all of your OEM emissions crap to pass visual. The best way to insure compliance is to get a TPI motor from the same year car as yours, and use all of the OEM emissions equipment from that motor.

On the other hand, do you know anyone local to you that you trust who performs emissions inspections? If so, tell them your plans, and ask them their opinion about passing emissions. If not, go to a local cruise, and ask about local inspection stations who are "friendly" to people in situations such as yours.

From reading your link, it appears the folks at classicjunkyard.com are scaring people into buying used AIR pumps and whatnot form them to pass emissions.

Hopefully, someone form PA who has a modified car will post here, and help you out. But I do not thisnk your situation is a dire as you think.

 

do the 50 state legal headers have the AIR tubes on them? If so your fine. just retain all the emissions stuff the car came with, Tbi and tpi cars do not have nearly as many devices as the old 305 smog machines. If the new motors headers don't have the AIR tubes you could get a set of the Edelbrock or SLP headers they have the AIR tubes. Where in PA do you live? I know a couple of guys who will pass you visually, just make sure it still passes the dyno test, unless you have an exemption. If you get an exemption but want to drive your car alot just get a second gauge cluster thats close to your mileage and swap em out when it gets close to time for inspection.

 

The headers dont have a.i.r. thats where i have the problem. I suppose i'll just have to sell them and buy ones with tubes on them. Or like previously posted i could just find a "friendly" guy:lala: . It has dynomax headers on it right now, and that bolts up to my factory y-pipe so as of right now i dont have to worry about a y-pipe.

Oh, by the way i live in central P.A. near selinsgrove and lewisburg.

 

I wouldn't worry about it. Most inspectors aren't that thorough. If they give you grief, tell them you drive the car less than 5,000 miles a year and you have owned it over a year. Then it is exempt from emissions. They aren't supposed to argue this at all. There are always loop-holes.
