914World.com _ 914World Garage _ Dual carb back to stock fi
Posted by: Curly! Jul 23 2021, 07:33 PM
Good evening from lovely NW Oregon, USA. It’s not enough to run an efficient, clean burning engine, here in Oregon, it also has to be a stock application. I’m fooked! The son in law thought he’d do us a favor and bought us an out of state ‘75 2.0. The wife had a ‘71 she drove for 10 years, 40 years ago. This car has a dual carb setup. I need to return it to (as close as I can get in order to fool the inspectors) stock FI. I searched, and I’m sure it’s here somewhere, but I’m not smart enough to find it. Can someone point me to an appropriate thread? Or feel free to answer in any way you deem helpful. Thanks so much.

Good luck! But by the time you get the FI restored and running, Oregon will probably outlaw gasoline.

Be thankful it is not a 73, which had some one year only parts. Go to Jeff’s site (https://bowlsby.net/914/Classic/) for a list of part numbers needed, and note that Jeff sells the required FI wiring harness. I am fortunate to have a friend with the knowledge and tools to dial in an old FI system, but there are countless articles and triage threads on this site - search is your friend

out of interest, whats going on in the USA with the smog stuff on such old cars.

That's surprising. I'm not sure where in NW Oregon you live but generally this only pertains to the Portland, Ashland, and Medford. If your car is older than 25 years you should be exempt as far as DEQ is concerned.

If you're in one of the dreaded locations, go rent yourself an apartment in a free zone for a month or so & register the car there.

Unfortunately, I am in the tri-county area. And the 25 year rule is a myth, in Oregon anyway. 1975 and newer have to pass DEQ. I believe that to be the first year pollution equipment was required. 74 and older get a pass. OTOH, I had a 76 BMW 2002 that I ripped all the emission crap off of and it passed every two years. About all they ever looked for was the gas nozzle inlet, to make sure it was the small one. I am hoping I can get this car lean enough to pass the sniff test, and that they won’t actually ask me to open the engine bay hood. It worked for 12 years on the 02.

Cars have to be registered at the same address as your license. They’re hip to the out of area registrations. People did it for years before they changed their rules.

The problem is going to be the cam
If a previous owner put a high lift cam into it for the carbs
That will disrupt the vacuum signal to the Djet mps
Due to valve overlap at high lift
And rebuilding the motor is the only way to change the cam
Can your son in law register it outside of the emissions zone?

Here is a page that may help you. Assuming its a Non-CA model 914 or that Oregon state testing requirmetns apply, you won't need the EGR system or CAT, although the CAT should clean up the exhaust significantly for the test.
In addition to the correct fuel injection system, you will need the late exhaust system, air pump and air injection system for 49 state compliance.

Register your car in Montana.

One option would be to convert to modern EFI. I've 99% decided I'm going to convert my dual carb engine to Microsquirt for this reason among others since they can be mapped to run with any cam (or so I'm told). There are even stealth setups that use the stock plenum air cleaner, intakes and even injectors and many of the sensors if you like. @http://www.914world.com/bbs2/index.php?showuser=18454 even has the ECU and wideband controller inside an OEM ECU case. Even if an inspector did peek inside the engine bay, I doubt they'd be able to tell is wasn't stock.

Yeah. According this the Oregon DMV website your car is exempt if:
"Vehicles older than:
Model year 1975 (Portland-Metro area).
20 years old (Medford-Ashland area)."
I guess your car is on just the wrong side of 1975.

Do you know what the exhaust numbers are now ?
Posted by: Mikey914 Jul 25 2021, 10:08 AM
I'm sure that they are looking at the sheet and it shows fuel injection. You can run an aftermarket as long as it passes. The only real issue I can see is if the car is a CA delivery and shows a CAT.
There are aftermarket CATs available.
Talk to Allen at A&P Auto Specialties on 82nd. He's a factory trained Porsche mechanic and has been around long enough to have done this a few times. I know he has an exhaust guy and could probably help you out. If not point you in the right direction.

Yes, I have a readout from the test center. Next week phase one, giving it to the local shop to see if they can lean it out well enough to pass the sniff test. If they can, perhaps the test center will choose to not look under the hood ;-)

Even if someone looks under the "hood", will they really know what they are looking at?
If you can get an aftermarket high flow CAT, could install it, get the carbs leaned out a bit and be surprised if it wouldn't pass. Given the engine is healthy and such.
