I currently have a head being built and am going to go with a 2.02mm SCE head gasket on my build. (Inline pro turbo kit)

I have a smog that is due next June (can get it done as early as April) and I was wondering if I should hold off on putting the head and head gasket on as i was worried that the lower compression may make the car fail due to the lower engine efficiency.

Any thoughts on if the head gasket and lower compression may make me fail emissions..

And yes I planned to pull the kit off and return it back to stock for the smog test for all those wondering...
That is whats required out here in Nazifornia unless you "know someone" but the nazis have hunted most of them down by now and put them in shackles.

 

im having a really hard time getting one in ny, i used to know a guy, now hes gone and no one will inspect my car, it sucks

 

Yes it's getting near impossible to find anyone to do "it" anymore, hence my thread.



Anyone got more thoughts as to if the 2mm head gasket added to motor will cause smog problems here in California? Again everything else will be put back to stock except for the built head and 2mm head gasket.

 

Well, passing a smog check depends on vehicle emissions (NOX, CO, particulates, etc), OBDII compliance, and a properly functioning & unmodified emission control system.

So long as your car:
*has the OEM ECU / OBDII in proper working order,
*doesn't run too rich belching out unburned hydrocarbons/particulates - the bad stuff
*is properly equipped with "OEM" grade emission components (cat, EGR, CARB approved intakes, etc)

Then any decent smog check station should give you a passing grade.

Now, changing the combustion chamber / compression ratio etc.... it's technically prohibited by the EPA/CARB regulations.... but extremely difficult to notice as long as everything else on the emission system is in working order

I would just go ahead and get it smogged once it's well tuned. You can have a "Eco-friendly" tune, you would need a piggy-back to maintain your OBDII compliance - I don't know that the stock ECU can compensate for that change in your VE / cylinder capacity / etc....

Youre nox levels will drop , however youre co and hc may go up . It might pass . Only one way to find out !

 

Thanks for the reply..
This is the kind of reply I was hoping to get.

I think I am just going to put my Inline kit on now for the time being with the stock head/gasket till my smog check is due and then put it back to stock for the test and then rip the head off, do the gasket and head change and retune to the moon.

I think this is probably gives me my best chance to pass.

 

I have been reading for a few hours and baring you put in factory plugs and have a good cat you should have no trouble. So the only problem would be the copper visual reference of the gasket.

I am sure there are ways to get around it even if there were more issues, with the type of fuel you use also. Using a higher concentration on Ethanol and alcohol seem to help.

 

just find a generous person with a stock s2k and put your reg on their window. pay the guy a little extra and tell him not to put the inspection sticker on the window. so your car is boosted and you don't have to pull everything off every time.

 

so who has a stock s2000 on long island and wants to be my friend?

 

"nazifornia"
rofl aint that the damn truth. man i feel for you members out there having to put up w that bs. i wouldnt think it would have any baring on your inspection unless it throws a code. at that point, you know the drill. unhook the battery . thats how ive passed my last 2
