There are a few ways to make it legal, you can update to a newer motor and get it certified with the newer motor. Then you need the emissions equipment that came on that motor. After the certification you would get a sticker in the doorjamb of your car with the new year and engine information that your car had been updated to. It would instruct the smog tester that for example "This car is a 1972 911T but it needs to be smogged as if it were a 1981 911SC".

The cops generally can't tell the difference. What they are trained to look for are a few specific aftermarket parts like headers, fuel injection rails and injectors, fuel pressure regulators, ignition parts, some things like that that import tuners tend to have.

The fuel pressure regulator in the engine bay of my friends 1970 914 was what got him in trouble with the CHP. He had a 1970 914 and got pulled over by the CHP. He had to find someone with an original 1.7 liter L-jet engine and swap it in in order to pass smog.

The best thing would be to make sure the installation looks stock. Colorful anodized parts or flashy logos or obviously non stock fuel lines and wiring would be a red flag.

Like I said, it probably won't even be an issue, but it's something to consider if you live in California.

... I've got a fuel pressure regulator that looks exactly like a decel valve. ;_0

Well, the aftermarket parts are installed.... in me. Had 2nd hip replacement surgery Fri AM and they kicked me out Sunday. I need to explain to them how rude that is. Half of my lower body looks like an NFL lineman... the other half, not so much. Maybe I can play by May-June. Haven't done anything with the car parts yet.

Newly upgraded parts. Does that bump you up in classing? Good to hear you are on the mend. Looking forward to hearing about your success!!!

We had the EFI installed on the engine test stand 2 days ago and I was really encouraged. Fired right up and the throttle response was much better. Pretty neat. HOWEVER, when it was installed on the car yesterday - the car starts up and idles, but is not roadworthy.... balky, stalls off decel and struggles. I've rechecked all connections to the MS relay board and the only thing that changed was shortening some of the cables to clean it up. I'll recheck my grounds today.

I have a used LC-1 (O2) sensor that has a calibration procedure but I can't calibrate because it's missing that piece, so I'll likely swap out to AEM unit (no calibration needed). It smells like it's running really rich. I don't own a laptop, so I can't change anything at this point - even if I knew how. My planned tuner in Napa just went on vacation.

Hoping to be ready for the 3rd AX, or maybe I'll miss another... but at least the hips are okay enough to get in and out of the car now.

And so it goes with custom EFI solutions. You will get it figured out just takes time and a couple dyno sessions. Once you get it figured out it think you will be happy. Glad you're feeling better too!
