1976 Is it a 49 state or Cali car? Options

[gnomefabtech]

Car came from Nevada but I can't tell if it was originally a California car. It still has injection but doesn't have a cat or smog pump. Doesn't look like it ever had either but I'm wondering since I'm going to try and register it here in California. Thanks in advance!!

Here is the Vin:

Wow!

I can give a couple of tips on emission control: The EGR system was developed solely for the reduction of NOX via introducing an inert gas (without oxygen-could have been anything) into the intake to dampen the temperatures achieved. A small amount of exhaust gas equaled a large combustion chamber temperature decrease. If you keep the combustion chamber below 2500F oxides of nitrogen are significantly reduced.

The air pump was utilized to add additional oxygen to the cat to allow the cat to burn the HC and CO out of an extremely rich mixture. (by today's standards). Without the supplementary oxygen the cat will stop functioning earlier.
Air pump keeps cat alive; it doesn't dilute the exhaust.

Damned interesting that cat cars got an automatic replacement at 30K.
Replacing a cat every 30k would get old quickly...

What I didn't know was why Nissan added EGR valves to the Z-car in 76 and then added nothing else (49 states cars) until 1979 when everyone went to cats across the board. The 75 Z FI manifold without EGR is a rarity.
Thanks Woki!

I've found getting into tangles with city and state officials is often more trouble than it is worth.

Good luck to you if you try. (IMG:style_emoticons/default/beerchug.gif)

not sherlock holmes mate.
just an architect.

this epa stuff is chickensh%t compared to negotiating your way through disabled access regulations in north antarctica. or regs that are about to come on line. like - public dunnies.
how many sexes are we dealing with again? 4? really? how many dunnies? who is paying for that? its not briefed. its not in the cost plan. how far is a deck allowed to be above the natural ground surface again? 1 meter. ok. make it 999mm and it doesn't need a handrail.

i'm used to looking at regulations real hard and trying to figure out where the slip up is that gives me negotiating space when i am dealing with a municipal building surveyor (inspector in amera-lish).

my motivation is never to solve a crime it is to "commit one". strictly white collar.
and not really crime just a manipulation of the rules and regs -----in my favour.
