Greetings everyone,

I need to buy EGR valve
(air control valve? ) for my
'84 rx-7 1st gen in order to pass
the smog test. Do you know a good
place for that? I checked the
links on the forum but they have other
years.

Thanks in advance..

There is no EGR valve in 84. If you can find out what you need, post it. Many of us have stuff laying around that you can have if you need it.

EGR is a Cali-only thing and I do believe it was on more than the GSL-SE but I could be wrong..

Now seeing as San Diego is in Cali, if your car was originally a cali car, you'd probably have an EGR :P Unfortunately, I don't have one to sell you so that sucks.

All I know is that for the regular old smog in other states, all you really need to make sure of is that your ACV (air control valve) is working properly, that your cats are good and getting air from the ACV, and that your combustion is happening efficiently. (ie: carb adjusted properly, quality low octane fuel, spark good and strong, air/oil/fuel filters all changed, and the oil has to be fresh and clean, because our engines are *designed* to burn some oil)

Good luck, Cali smog is supposedly the hardest in the world to pass

Thanks guys. I am a rookie so
I messed up big time. What I need is
ACV. Do you know where to buy it?

Hmm....

Well, it's gonna cost you a couple of limbs and your firstborn at the Mazda Dealership, that is IF the part isn't listed as *discontinued* like the darned rear brake line is...

However, you can probably get one here off the forum. Sure it'll be used, but if it works, that's all you need it for. Many of us in places where there is no smog testing take our ACVs off when doing Rx7Carl and Pratch's "Emissions Removal Tutorial" (http://maz_tutorials.totalimmage.com/) and I'm sure there'll be a couple of folks more than willing to part with their old ACV to help you out.... not sure how many of them actually *know* the working condition of theirs though, I'm sure someone does.

Yeah, with any luck you should be able to pass with a working ACV and some good cats (there are THREE of them with the car stock...). A word of advice about catalytic converters though, if you replace the stock three with an aftermarket one, only keep the aftermarket one on there for smog tests. I'm serious when I say that the hotter exhaust gasses our rotary engines make *eat* right through aftermarket cats and mufflers in no time flat. If you're keeping the stock three, or buying proper replacements for them (www.victoriabritish.com has a catalogue you can get for free), then you're safe to go. Depending on how bad your ACV was and for how long, you may need to replace at least one of your cats... without the extra oxygen provided by the air from the ACV, your cats may have clogged or melted slightly. May or may not be something to worry about, just something to keep in mind.

Hope this helps Again, just make sure your car is properly in tune, use quality LOW OCTANE fuel, and get that ACV and your cats working. The low octane thing isn't just for better smog tests, it actually is for better running of your engine at all. It has been covered rather extensively in the past, and gone through almost as many debates as the choice of oil, but the general concensus is that if you're running your car N/A (ie: no turbo), then you want low octane. When Mazda used to race these cars, they'd bring special 83 octane "race fuel" with them because nothing at the racetrack had low enough octane... it's a long explanation, but trust me on this one.

Again, Good luck
Jon

edit: if you do have an originally cali model of first gen Rx7, you might have an EGR to worry about. I'd grab a heynes manual and check it out. A Heynes manual is probably the best $20 you ever spent... and have you changed your fuel filter this year?

How many do you want?

Thanks a lot, vipernicus. I will try
to follow your advise. I have Hayes
book and you are absolutely right about
it. The problem is I am worse than a rookie.
First time in my life I started to take care
of the car by myself. I will try things and
tell the results.
Thanks again.
