thats what kills me:laugh:

"guys we need to regulate cars that pollute......lets test everything but their pollution output"

To be fair, this is only true if the sniffer test covers all operating conditions. Cold start, warmup, WOT under boost, etc.

Since the OBD-II system is always there, monitoring the car under all operating conditions, it is a better indicator of performance under conditions other than idle and steady-state operation at 15 MPH and 25 MPH.

You've got me there. Though they seem to primarily be concerned with emissions of vehicles travelling more than a couple blocks given their testing methods. I live in a small town, your OBD-II example would seem more effective for my local area.

For that matter why are there different ppm ratings for different vehicles and engines not 1 level for all per year? From the data I've seen my truck ('07 B3000, ford 3L) is allowed to make more pollution per volume of exhaust than an mx5 of the same vintage.

I just get a little irked every time I read about emissions testing hoops to jump through and recall an emissions loop hole we have here that requires vehicles 99 or 00 and older that have a swapped engine to pass generic 1980 testing (gas cap pressure test +sniffer with ludicrously high limits). IE I would pass more easily with a cat-less carbed 454 miata than a turbo bp.

Because your truck is a truck, and your car is a car.

It's the same in the US. Trucks (including SUVs) are held to a lower standard than passenger cars, and among passenger cars, there are numerous different categories, each with different requirements. Why is this? I honestly have no idea, but I'm sure it goes all the way back to US President Johnson's knee-jerk reaction to the German tariff on imported chickens in 1963.

The standards are what they are. No sense getting worked up about it, just learn to play the game.

And we all do. We just like to bitch about it in the process.

So, My DIY turbo 1968 SAAB converted to RWD with a newer engine (94 Miata) would be exempt or does the newer motor have to have all pollution controls that it originally came with in 94?

18psi 12-09-2012 12:12 AM

nope...good to go

pre-76 cars are so overpriced here because of that. like when I was looking at datsuns, a 75 and older one in terrible condition will still fetch a solid 500-1000 premium over a cherry 76 and up

Any vehicle older than 1976 is exempt from testing, regardless of what's been done to it, including engine swaps.

If you do an engine swap in a vehicle newer than 1975, it's actually not all that difficult. The engine has to be from a comparable class of vehicle (eg: you can't put an engine from a truck into a passenger car) and of the same model year or newer relative to the car it's going into ('94 engine into an '82 car is ok, '82 engine into a '94 car is not.) You also have to carry over all of the emissions controls from the new engine.

Sounds good.

Until this part.

Almost makes swapping in an ERod LS3 seem reasonable.

You also have to ref it, and when you take it there, they bust out a giant retardedly outdated book by which they "inspect" your car, and regardless of common sense if the book tells them something different from what they're looking at, they fail you because they don't comprehend teh internet or anything else allowing them to look up more updated "specs" on each car.

It took my friend 7 months to finally BAR his B6t festiva. Oh the stories he has about those idiots

Sorry for replying now. Didn't think there'd be so many responses. I write WTB post in the morning and come back to a number of responses.

Regarding your question, it's not that the Greddy system is too much, I think the guy is asking too much for it (ust turbo alone). He's asking for $600 for just the turbo which I think is much...or am I wrong on that?

I know a Bell kit won't be cheap and would cost more. I'm just seeing if anyone is selling a 2nd hand one that's CARB approved (anything 2nd hand is cheaper than brand new)

18psi 12-09-2012 02:04 AM

2nd hand carb approved setups around here come about like once in 2-3 years.

so good luck with taht
