Well, with my registration due tomorrow, I went and had a standard smog check, as per California State laws, the first one I had to do since its now 5 years olds. For those of you who don't live here, a car doesn't have to be smogged checked until 5 years from the date of purchase, or when it changes ownership, then its checked every two years. It was smogged checked using a dyno to load the car.

My car:

00 Civic EX (D16Y8) with 98,500 miles (28,500 with turbo)
New cat was installed 18 months ago before the turbo @ 68,000 miles
Edelbrock turbo kit (CARB E.O. legal) @ 7psi, intalled @ 70,000 miles

Smog Test Results:

15mph (1943 rpm)
%CO2: Measured = 14.7
%O2: Measured = 0
HC (PPM): Max allowed = 64, Average = 9, Measured = 28
%CO: Max allowed = .55, Average = .02, Measured = .03
NO (PPM): Max allowed = 477, Average = 57, Measured = 0


25mph (2007 rpm)
%CO2: Measured = 14.6
%O2: Measured = 0
HC (PPM): Max allowed = 47, Average = 7, Measured = 14
%CO: Max allowed = .54, Average = .03, Measured = .02
NO (PPM): Max allowed = 764, Average = 50, Measured = 0

I was very happy to see those numbers! With how many miles I have put on it with the turbo, and how hard I like to drive, I was worried.

It was also nice to know that the Edelbrock turbo kit will run that clean in the long term!

 

Does the turbo kit use stock injectors?

Stock injectors with a secondary set used to add fuel with boost, stock fuel pressure/fuel pump.

The smog tech didn't check for E.O. numbers untill after he ran the car. He didn't care about the equipment on the car, just ran it.

I would reccommend to anyone going to do a smog check, to have the equipment list for the turbo kit on hand in case you get a picky smog tech, for the visual check.

 

Cool, man. That's basically how the JRSC passes smog, too. Pretty much any setup that uses stock injectors + FMU or stock injectors + piggback secondaries that only add fuel during boost will run like a stock car when it comes time to smog.

Even still....I was worried going into the smog check. Especially since I waited until the last minute to do it!

 

Hallo,

i have a question, my car (b16a1) uses 280ccm Prelude injectors and is good tuned, closed loop is enabled and working.

Here in germany we have a exhaust gas test, but when the car stands still at aprox. 2000rpm-2500rpm, so no load on the engine.

my A/F is fine at 14,7:1 so this test is passed, but my CO values are much too high.

i have a 100cell race cat, maybe thats the problem, but i have many ppl they say thats no problem with such a cat, so my question, is there any other reason why my CO values are too high???

Thanks
Malte.

 

that's awesome!!
