Tom,
I am trying to get my 90 Z to pass CA smog, are you running stock manifolds and cats?

Tom,

Yup.

Flowmaster cat back exhaust system and Haibec prom installed after prior smog.
Has fresh plugs, recent oil change, and fairly new injectors (installed 3 years ago but only 1000 miles or so on them) and a tank full of Chevron's best.
Just prior to smog I drove the car about 18-20 miles at freeway speeds or better :-D in 3rd and 4 gear, getting her nice and hot.

Congratz! :cheers: Now try not to have too much fun and post some pics (or a video) of you driving on a twisty mountain road. That way those of us that are snow bound can live vicariously - at least until March or April!:cry:

Tom,

You will never get it to pass without the Stock cats in (AZ or CA). I have tried the HiFlow Random Techs and Magna Flos with Jeal headers and no dice. Just a sniffer test fine but once it gets worked out on the treadmill your toast.

[tccrab]

My gut feeling is that a good running stock LT5 should have no problems passing the California Smog Nazis.
Even a good running reasonably modified LT5 shouldn't have too many problems passing.
Again, the operative words are "Good Running".
A bored and stroked 427 running 703hp, hmmm.... probably not.
(congrats, it's a Monster!!!).
Even cars with headers and aftermarket cats, if they're the right cats and the LT5 is running right, it really shouldn't be that much of a problem.

All bets are off if it's got leaky injectors, bad coils, old spark plugs, or big vacuum leaks in the top end.

Mine would not pass. New Aftermarket hiflow cats, New coils, new injectors, new plugs, new wires, new Secondary tubing and actuators, plenum gaskets etc. It was running great and I ran the snot out of it to make sure it was warmed up. It was my belief these new stainless hi flow cats disipate the heat too fast and the emissions dont burn correctly. Im am sure if you placed a generic regular syle replacement cat under there it probablly would pass. I am only relating my issues in AZ with these Hi flow stainless cats. It will never pass the treadmill roller test undriving load.

I don't think I've seen your #'s, what was out and by how much?

Mine has 92k miles on it and ran even cleaner than that.

Rick:

What mods do you have on yours?

My first attempt to pass was w/Stainless headers and random tech cats, I replaced the cats w/CA approved cats and it still failed (emissions #'s were virtually unchanged w/the change in cats)

1. Top end porting.
2. Borla challenge exhaust system.
3. Open air temp senser rerout.
4. Finolic plenum spacers.
5. Haibak chip that had been reprogrammed by Corey Henderson.
Thats pretty much it. Accept for the spec clutch which is NA for emmisions. I'm still running stock manifolds and and cats.

I would like to know how you even got to the ''testing'' stage as it should have flunked the visual with the LT headers.

Up here they would have sent me packing. I'm just jealous.

Hiya Steve!!
Long time no talk.
I plan on being up there for Cool April Nights, I'll keep you posted.

About the headers, there is a way to get a BAR/CARB waiver for the '90-92's because the catalytic converters are an integral part of the exhaust manifold.
There are no new replacements in the GM inventory, haven't been for years.
All you gotta prove to the smog nazis is that the originals failed, and there are no new ones available anywhere, and nobody makes headers that are CARB approved.
Easier said than done, or so I'm told.
On the '93-95 the cats are a separate unit bolted to the exhaust manifold with a flange and thus are easily replaced.
So in the immortal words of the soup nazi:
NO HEADERS FOR YOU!!!

Hi Tom,

Good to hear from you. If you come up for Cool April Nights we'll grab a beer somewhere and split a waitress...:mrgreen: It would be good to get together. Be sure to let me know.

I never gave the 90-92 cat arraingment much thought before but it makes perfect sense. I guess it sucks to be me...or ...another good reason to get the heck out of this state....

I wised up 17 years ago and got out of there. Redding is on the oregon border which is pretty much the middle of nowhere.

Rick:

I grew up there.
I have many fond memories of my misspent youth. :-D
My dad ran the Toyota Stealership in town, my first job was washing new cars.
After doing that for just one summer I decided I wanted to go to college instead.
Muscle cars were common and cheap back then, by the time I left at 19 I'd already had and sold half a dozen or so.
Of course it helped that I got first pick of the trade-ins at Dad's shop.
Wish I had kept some of them, they'd be worth big bucks now. *sigh*
Cruising on Friday and Saturday nights was a big deal for the young crowd then and it wasn't illegal like it is now.
Street races and stoplight to stoplight barnstorming was very common.
My favorite memory (now, not then:() was when a local Police Officer (one of my Dads customers) showed up at the shop one fine morning and told my Dad: "We know it's your son, we haven't caught him yet, but when we do we're going to throw the book at him".
Needless to say, my street racing days were numbered after that.
It was probably a good thing that I left for College, otherwise I'd probably still be cooling my heels in the slammer.

Tom! My mother lives in Roseville. My dad lives in Manteca and my step brother lives in north Redding. My step brother has been in San Quinton twice. Folsom and Solidad. He's institutionalized. But he likes living in Redding because he says there's nothing there to get in trouble for living in the hills.
But I've always wanted to know how my ZR-1 would handle the steep streets of San Francisco. That would be fun. But you'd better have a good clutch and good brakes. Some of them are 45 degrees straight up and down like knobb hill.
