what gas to use to pass emissions.
1988 turbo FC. Full built motor with street port. Was running an E8 possible now a PS2000. Must pass emissions and I was told due to the porting it would not. Can I run some other type of fuel to pass emissons then run back standard fuel? Thing is I have way to much in the engine to go back into a stock motor. This motor has new housings and doweled etc etc. I even have a brand new Mazda cat. Posted the motor for sale but hard to get any bits even for 1000's less then what I paid.

I should think that you might want to change your ecu map, not the fuel you run, for help with passing emissions and inspection...
Lean it out down low so you pass, than change it back before you break something.
Btw- this question doesn't really belong in the Single Turbo section, as it has nothing to do with single turbos.....

Yes e85 will pass, if you can't get straight gas to.

E85 will help but isn't a guarantee. if it is just a streetport you should be able to pass on 100% pump gas with a decent tune.
if it's having trouble and you can't dilute the gas with E85 you can find denatured alcohol(ethanol) at your local hardware store. add in enough until you pass then fill up the tank with your regular gas.

Thanks,
Figured it belong in here as single turbo forum is where most of the modified aftermarket topics are.
My local tuner said that it will not pass no matter what on pump gas with a big street port. I asked the builder who build my motor if it would pass emissions he just laughed.
Just figuring out what to do with my 10th AE once I receive it from the body shop. I jsut want to pass emissions legally and as previously mentioned I probable can't give away my brand new race motor. LOL. I wanted at least 5k for it.

if it was a bridged or PP motor, i would agree with them. the ported and tuned engines actually ran cleaner than they did when they came in on stock ports with stock ECU. sure, a radical port may need a bit of tweaking but it is still doable unless say running 850cc+ primaries with a PFC.. some ECU's have limitations.

Wow. That emission test looks like it comes from a Honda civic lol. The engine builder I have faith in and the tuner tunes race rx7's so there is no question on the tunes stability. Not sure how many were tuned to pass emissions. So seems like there is some faith to rotaries passing emissions. I should state that here in Ontario Canada we are going to a new format of testing. OBII computers don't even hit a smog test. It's all based on computer codes. For older cars will have to pass a curb idle. Rotarys are aweful in idle!
So since I have a brand new main catalatic converter I just may try to emissions with a full blown 400rwhp. Either that it will be a V8 FD but having an 8K motor rot in the basement is not cool. Man LS3 engines with 500hp is 8K LOL.

An emissions test in Ontario is $35 with no provincial tax. If you fail it has no bearing on future tests other than you can get your second test at half price (if you demonstrate you did something to improve the emissions, spark plugs, etc.)
If you pass, then great. Thread over. If you fail you'll have a report showing where you're over which will point you to what you might need to do to pass.
When I got my 7 I took it over to the emissions tester near where I live and I failed. I was just barely over in HC. I changed the plugs and went back and passed.

most tuners don't give a rats *** about emissions unless they actually have customers come in who need cars tuned for emissions.
i built cars in california, the strictest smog state. most tuners just are too ADHD to sit there and tweak idle maps to the point of the car stumbling then add in a touch of fuel. most tuners tune rich because it makes the engine happier but for inexperienced tuners that is all they know how to do. those same tuners also do not know how to tune for economy, because the same rules apply to those for tuning to pass emissions, a light touch versus a sledge hammer.

I've tuned a car with an emissions analyzer in the tailpipe with a small streetport on an REW block before. Having the cat stupid hot had more of an effect on the emissions then anything I did on the tuning side.
It needs to idle clean without missing, if the engine can't achieve that, it reduces the chances of a pass. I think the term "streetport" is overused. That can mean an extremely wide range of possibilities. Some can pass, the extreme ones won't.
IAN, Dave's primary ports aren't that aggressive, neither are his exhaust ports, so there is always a chance. The new idle rules are supposed to be easier now too. But I wouldn't bet on it honestly.

It's TitaniumTT's car, and he was using a Magnaflow cat. He has it mounted with v-band clamps like my car.
You can read about his emissions thread at the following link. Unfortunately, the children who run this website have the "other" rotary website automatically blocked on this forum, so I need to post the address in code.

well, alcohol doesn't produce hydrocarbons.... *wink wink*
it also lowers NOx, not that rotaries have issues with that usually. CO is basically how efficiently your cat is converting the emissions but misfires will greatly increase CO(loping idle or faulty ignition).

I have a stock S5 I need to pass smog with that I just got restored. So all I need is small tips to help insure I pass.
