johnc Posted December 29, 2008 Share Posted December 29, 2008 1974 260Zs sold in the USA did not run catalytic converters. Quote Link to comment Share on other sites More sharing options...
Gritz Posted December 29, 2008 Author Share Posted December 29, 2008 1974 260Zs sold in the USA did not run catalytic converters. Cool, thanks for the quick answer!!! So now my plan is to run a 3" exhaust with a straight though muffler and resonator, the 1jz should sound awesome!! Quote Link to comment Share on other sites More sharing options...
mark Posted December 30, 2008 Share Posted December 30, 2008 In NC anything that is 35 years old does not need an inspection of any kind. A late Merry Christmas to you. My 73 became exempt last year. Quote Link to comment Share on other sites More sharing options...

chrism Posted December 31, 2008 Share Posted December 31, 2008 Can't wait for my 75 to be exempt. When I got the car, it hadn't been inspected for 10 years. I figure why start now. So far so good. I'm gonna cross my fingers and hope no one notices. Quote Link to comment Share on other sites More sharing options...
vashonz Posted January 3, 2009 Share Posted January 3, 2009 Cats are not all bad, it really helps with the smell. I have one on my '71 and we don't even have emissions stuff where I live. Quote Link to comment Share on other sites More sharing options...

PanzerAce Posted January 9, 2009 Share Posted January 9, 2009 1974 260Zs sold in the USA did not run catalytic converters. Don't suppose you have a table or something that has that info? Or if you know if *any* '73 240Zs came with a cat (Dunno if there was a Cali model that did). Quote Link to comment Share on other sites More sharing options...
Tony D Posted January 9, 2009 Share Posted January 9, 2009 No Datsun manufactured anywhere before 1975 had a catalyst on it. The catalysts were installed on Japan Domestic Market offerings starting with the EFI versions. If your Z came with carburettors on it, it did NOT come from the factory with a catalyst. Period. Federal cars did not get a catalyst until 1981 when the 17 digit VIN system came into being. California Spec cars had catalysts starting in 1975, and went onwards from there. Elsewhere, like in Europe, there were no catalysts or even EGR on the ZX's even in 1983. They didn't even get ECCS, they had an EFI system with an E12-80 distributor set up for a pneumatic advance/retard cannister like a 63-66 Corvair Spyder/Corsa Turbo!!!
