SVT Header swap and California emissions - Page 3

SloFoFo · 11-05-2009, 08:58 PM

Man, i'm not trying to brag but i'm so glad we don't have smog tests in AL. I'm wanting to swap an SVT header on my car and found this thread... You guys go through a lot just to squeeze a little performance out of your rides. I'd love to live in CA for the beaches and silicone, errr... the valley. But if I had to go through this it makes me think twice. Props for doing it right.

As far as visual inspection goes, a friend of mine had his svt smogged a few weeks ago and they thought his header was aftermarket (although they should have known other wise since the car is equipped with vct). It just depends where you go and how leanient the smog tech is. Some will fail you on the spot. Some will smog it and see if it passes or not. As long as you don't have the egr removed or any vacuum line disconnected you might get lucky.

For those of you who decide to get the ref smog it. I highly recommend taking off ANYTHING that is obviously not legal (i.e. HID headlights, non dot approved tailights/headlights, loud exhaust, euro plates etc etc etc) they can and possibly will cite you for anything they want to. In other words kiss some ass

I got a converter (old style,cheaper) for my 86 toyota truck in dec 2008. Didn't have any problems when it was smogged in July 2009.... (and I did see them go under the truck)............

The grandfathering is being accomplished via availability. Unless you yourself go out of CA to get the converter, you can't get a non-CA converter in california (local stores won't have it, mail/internet won't ship it to you).

The older the vehicle, the more likely that a converter needed to be replaced............. so a new converter on a new vehicle will probably be more likely checked for being valid....

Somebody make a sticky for california emissions lol. These posts pop up so often.

x2 swappin it for a day every 2 years isnt that big of a deal.

i was aiming for that eventually if I could pull this off properly

right now its going to wait a little longer, as I received my notice that i do have to get smogged this year

pointless waste of money

so basically most svt headers (generally speaking) have the egr bung, unless you remove it and/or dissable it with a tune correct? the the heck does the EGR do anyway?

As far as the EGR, I was curious and looked it up the other night. I was going to paraphrase it but I'd probably muddy the waters so here's an excerpt from Wikipedia and a link.
"In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in most petrol/gasoline and diesel engines.
EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. In a gasoline engine, this inert exhaust displaces the amount of combustable matter in the cylinder. This means the heat of combustion is less, and the combustion generates the same pressure against the piston at a lower temperature. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture.
Because NOx formation progresses much faster at high temperatures, EGR reduces the amount of NOx the combustion generates. NOx forms primarily when a mixture of nitrogen and oxygen is subjected to high temperature."

That's the gist of it but here's the full link. http://en.wikipedia.org/wiki/EGR
It seems halfway counterintuitive but it makes some sense too.

The stock SVT header does not have an EGR bung. A SVT header conversion kit made by Ford specifically for replacing the stock exhaust on a standard ZX3/5 has an EGR bung and a revised EGR pipe as part of the kit. The kit also states to use the header kit with a stock SVT cat and SVT flex pipe.
So if you buy a used, non-kit SVT header, you then somehow need to delete the egr hardware, usually with blanking plate(s).

Kit part number M-9430-ZX3L Most of the sponsors here on FF sell it.

It also gives better MPG while at cruising speeds. It takes up X% of the cylinder volume so less air fuel mixter and better MPG.
