I'm planning on buying a rust free 280Z in California or Arizona and driving it back to Virginia (my 240Z rusted out years ago). Is a smogged California car different (more polution control) than a non-smogged 280Z? Do all 280Z year models have catalytic converters?

Yes, the L28 in the 280Z has a smog air-pump and a few other goodies. You can rip them off though, and if you plug the holes there will be no bad affects. I ripped all that junk off my L28, and it ran exactly the same as it did before. Just about 25 pounds lighter!

I don't know. Anybody else?

Disagree on Smog Pump

I have a '77 California 280Z. It has a catalytic converter, a vacuum flow control regulator on the BPT valve, a BPT Valve, a PCV valve, and an EGR valve. That is it as far as pollution control devices are concerned. It runs strong. I don't see anything in my Nissan Service Manual that indicates that any of the '77 models had a smog pump. The catalytic converter, I believe, was only installed on California 280's until the ZX model came out in '79. All of them had the converter.

Not all zx came with the cat!
My 79 is a fed non cat from the factory-right on the factory underhood decal,no cat,no air pump. just the basics,egr valve and so on.

Re: Disagree on Smog Pump

> I agree with Phantom. 280Z's were fuel injected/electronically ignitioned. Due to improved fuel management an AIR (air injection reactor/smog) pump is unnecessary. However, the catalytic converter, evaporative cannister, fuel tank restrictor, and EGR valve are required (at least in Colo Springs). No right thinking exhaust shop will risk fabricating/installing an exhaust system excluding a CAT. The fine is around $100K. mikey
