a 912 e question about smogin california Options

[rosenfe]

i know its not a 914 but similar engine.im looking to buy one.owner had engine rebuilt 100 miles ago,nice car,but thermals are gone.he says that if it fails smog and ca. state bar cannot locate new thermasl,it gets a waiver.is this true and are new thermasl nla?.


i would prefer not put them on anyway.parts haven says nla.

The ultimate in aircooled technology available today applied to the 60-70's products
would certainly improve the emissions count.
I haven't read of anyone adapting direct injection variable valve timing and modern cats to the engines.Running a late model liquid cooled h4-6 demands that the engines smog equipment is intact,right?The sniffer does a comparator curve fitting routine for the model of engine or vehicle or both?

Requirements state the emissions equipment be present for either the engine or the vehicle, whichever is NEWER. Drop a 2014 Subie motor in your car, it MUST have every bit of emissions related equipment present in the donor car when it was certified by the Air Resources Board. That can mean the instrument cluster, the wiring and electronics, and usually the transmission and it's electronics.

Drop an '83 911SC engine in it, you'll need all the emissions electronics and hardware, as well as an evap system compliant with '83 regulations. Not such a big deal.

My take on the 912e, based on some experience here in CA, is it'll pass w/o the thermal reactors, which all but the most stringent of smog tech will not even recognize. You will, however, need a functional air pump system, the stock air filter housing, and a lot of prayers that the airbox will allow you to get it lean enough to pass the tail pipe test. If the car has solid lifters, setting the valves to .016" for the test will drop the HCs immensely, and you should run the test only after filling the near-empty tank with the lowest octane fuel you can find.

Remember, the SELLER pays for and provides the smog certificate, and it's a responsibility he/she CANNOT abdicate, and the buyer cannot legally waive, unless the buyer is a dealer or dismantler.

Edit: Hmmm. I forgot to answer the above statement. You can provide "modern technological" answers for the emissions equipment and "numbers" in CA, but everything you do will have to be ARB approved as individual pieces AND as a whole, meaning you'll have to spend literally tens of thousands (and probably even hundreds of thousands) of dollars in the testing and approval processes necessary to gain that highly sought after ARB approval number.
