Turbo and emissions
I have been getting a lot of conflicting answers about this question. I have read from a number of posts on this board that the GReddy turbo will not pass emmisions. I was just told today from a very trusted source that the GReddy turbo is emmisions friendly. Anyone have any hard facts on what the deal is with emmisions and the GReddy turbo?

"Please be aware these kits are NOT emissions legal, and DO void your car warranty from Mazda"
Also the Instructions state the same thing on the last page. They would sell more if it was CARB legal so you would think they would be working on one. LINK

In the recent SCC (Sport Conpact Car) magazine they had a segment on superchargers. One of the positive points they pointed out was that SC's will be easier to get CARB certified because the turbos will take longer to warm up & light off the cat. In that first minute or so it gives off like 90% of the pollutants that the car will put out on a trip. So the turbo will have great difficulty getting CARB certified. Take it for waht it is worth.

For some people this issue doesn't matter. In New Jersey you do not have to get a NEW car inspected till it's 4 years old. By that time many owners will be onto their next car. So if you have to money to fix it yourself then why not enjoy the Turbo.

I actually passed emissions without a cat on my '97 GSX (turbo) in '99. Since turbos generate a lot of heat, I was told to rev the car up on the way to inspection and get the pipes nice and hot. Hot enough to burn off the particles on the way out of the exhaust. I don't know if it's true or not, or whether it applies to 8's with the Greddy turbo or not, but I passed.
Oh yeah, I was running about 16-17lbs of boost, so it was probably a lot hotter.

Also, a rotary puts out a lot more emissions than a piston, even though the rx8 has side exhaust ports now instead of peripheral exhaust ports (which help with emissions) I still REALLY doubt it'd even come close to passing emissions with no cat.
For reference, my 2nd gen rx7 had no cat when I bought it, got it tested at a nearby Shell station before I knew this and it blew 2015 HC at cruise and 1876 HC at idle. Take it for what its worth to you

I think they put the cars on rollers here in Illinois also. Never had to do any inspection in Florida.
Since right now there is no CARB certification for any of the forced induction options, they right now are teasers for people like me that both intend on keeping the car for an undetermined length and need to pass emissions.

Very expensive and/or time consuming to install and remove for every emissions test. Though at two year intervals I suppose it is an option.

You just have to weigh your options. For my 2nd gen rx7 I do an exhaust swap and put in my "custom" emissions equipment with custom routing when it comes time for the test. Only had to do this once so far, took half a day, took the test, came home spent the rest of the day swapping back. Didn't bother me much.

Hmmm...if only I can convince my sister in Miami Beach to let me register my car under her. Don't think they have emissions in her county.

I guess it depends on your state, and their standards for testing. California is very strict on their testing standards. From what I've been (told), the GReddy turbo kit wouldn't pass an emissions test on several different standards, one being the visual inspection portion of the test here. Basically, the open air filament would be the initial indicator to the tester of modification to the vehicle. Cold air, and short ram intakes are not approved for California. I have decided against going with the turbo at this point because I definately don't want the hassle of taking things off and on..maybe there will be more options in the near future for me here in California.
