Out of state 911/smogging...
Hey all...
Soon, (within the next 6 months), I'll be purchasing my first 911. Likely a mid to late 80's model, and possibly from out of state. I'd like to know what experience any of you Southern California folks have regarding smogging an older, imported-from-out-of-state 911. Any input will be greatly appreciated.

If I recall correctly, the 911 became 50 state-emission compliant in 1980 with the introduction of the oxygen-sensor-modified CIS injection. (I'll have to confirm that.) So, you won't have a problem with equipment compliance issues... well, as long as the car isn't modified. Even if it is modified a bit from original, the casual smog check technician may not catch the details or may not care to look for the details in a visual inspection. That part is up in the air. You may get suggestions from people for smog check stations that are "preferred."
Passing the tailpipe emissions test will likely be a non-issue. If the car is stock, is running well, is properly tuned, and has a functional cat, you will not have a problem. My unmodified 1978 911 ran way, way below acceptable limits on all tested exhaust gases when smogged several years ago.
If your real question is about getting a modified car successfully through smog inspection, then you're on your own... or you may want to have more private discussions with successful individuals.
You probably know this... If you buy from within CA, the smog check is the responsibility of the seller. If you bring in from out of state, it's your responsibility. Know what you're buying. If you do bring a car in, you can have a pre-test done at a smog check station. They will perform a test and not send results to the DMV so you know where you stand.
good luck on the hunt,
Brett

Thank you very much for your help. If that is verified info, then I am a happy boy!

I recently got my '85 smogged (CA car since new), and noticed that they tightened up the requirements by ~30+% since it was last done in 2009. Here are the requirements as of Sept 2011, as listed on the printout - in case you want to compare the numbers from an out-of-state smog check.
This is done on a rolling dyno-like device, at 15 and 25 mph:
no spec on CO2 or O2
15 mph (my rpms were 1513)
HC: 97 PPM
CO: 0.59 %
NO: 804 PPM
25 mph (my rpms were 1729)
HC: 79 PPM
CO: 0.65 %
NO: 685 PPM
In all my years of getting this completely stock car smogged, it has never failed, but does sometimes come close on the NO if I don't drive it on the freeway first to get the cat warmed up.

Trying to find a DD 78-89 Targa in SoCal to drive back to Maine with my son next summer. My niece is getting married in Glendora. I'm afraid my wife is going to monopolize my new acquisition since she use to own a Cabrio. Oh well, 2 Porsche's are better than 1!!! Will go thru AZ. Will do In-n Out!

As noted above, they lower the limits over time- as cars average newer, then the requirements get more stringent. What Brett tested to years ago will be different than his next smog check. 
If it all is there, and in good tune, you should be fine.
