Guest ZDreamin Posted June 5, 2002 Share Posted June 5, 2002 hello all simple question, when were catalytic converters put on Z's?? thanks Quote Link to comment Share on other sites More sharing options...
Guest Tim78zt Posted June 5, 2002 Share Posted June 5, 2002 I've had original 78 Zs both with and without cats, so I would say it depends on whether it is a Calif or federal car, but 78 would be a safe bet. Tim78zt Quote Link to comment Share on other sites More sharing options...
Mike C Posted June 5, 2002 Share Posted June 5, 2002 I was pretty sure that cats were mandated in all vehicles starting in 1975. I know that was true on domestics, and would surprise me if imports were exempt, but I guess it could be on smaller engines. The '78 I just cut the exhaust off of had a cat.

Sumo Posted June 5, 2002 Share Posted June 5, 2002 I have a 75 Texas Z and i only have a resonator on it. I think it started in 75 for California to have cats on but 78 import and domestic for all states. I'm not sure about that though so dont hold me on that.

Guest Anonymous Posted June 7, 2002 Share Posted June 7, 2002 Mike, Your correct, 75 domestically was the year of the cat. I think domestic trucks was a few years later at 1977/78. Imports I'm not sure, I'm pretty sure that California demanded cats on them as well from 75 on, but can't confirm that. I know that 1974 was the beginning of a really bad serveral years of performance, things were really on the decline and it took till the early 80's before it returned. 4sp's were nearly impossible to get in like the otherwise nice mid-late 70's camaro's for example. You could get the 4sp in every state but Ca.,I think maybe because they didn't want to mess with trying to certify it smog wise, or they knew it wouldn't make it. Also interestingly enough it was the time of the gas embargo lines (no embargo just a ploy to raise the price). For those not old enough to remember, they even tried metric measurment (a litre instead of a gallon) so you'd think you were'nt getting screwed paying for like 3/4-7/8 of a gallon for the raised price. They put a conversion formula on the pump needless to say, people hated that alot and it ended shortly thereafter.. Ok, enough with the history in review...

RedNeckZ Posted June 8, 2002 Share Posted June 8, 2002 Most non-Cal. cars didn't need cats until 1978. Even then most didn't have them. It really started in the 280ZX model in 1979. Only then did you get the cats on every model. I have had five 1978 280Z that didn't have the cats. All had the original pipe still on them. Hope that helps.
