twin-turbos illegal???

Could you possibly find a more vague instruction than that...what is the CHP thinking putting that out?

Going as drastic as adding forced induction to a normally aspirated car might not pass the sniffer, but more than a few power mods have been PROVEN to IMPROVE emissions. The first one was the use of tuned headers back in the 70's when all this came about the first time. Headers have been proven to increase mileage, and power while reducing one of the emissions molecules they test for (I don't remember which one right now). Most "reprograms" of ECU's still pass sniffer tests. It is not written that making power has to be noxious. Some end up that way, some don't. Mainly on the old carburated (sp?) engines where you don't have finite fuel controls.

I understand the CHPs desire to put up such a broad statement. I just wish they were more realistic in handling the hot rodding world.

One other thing...

1st Gen RX-7s were 1979-1985. You have more than a while before they are smog exempt. Also, along the same lines, understand this common misconception - The exemption is only from the sniffer test. You are still required to maintain all factory installed and federal/state required smog control equipment. I personally know a few people that had early 70s Novas, pulled the cats off and now have big tickets for disabling factory installed and federally mandated smog equipment. The exemption doesn't mean that you don't have to use the smog equipment, it just means that you don't have to get it checked every two years anymore.

It just means that no one is checking except for safty checks and maybe a snooty cop. Just cut the cats open, clean em out and run the pipe right through it and weld it back so the weld faces the underside of the car. The inspector looks, the stock cat is their, and the sniffer doesn't care. You just have to be smart about these things.
