Yep CA SMOG Emission TEST ONLY time!
I finally saw why I am a "Test Only" Vehicle.
My car is a, or "fits" the "High Emitter Profile".

My 59,000 mile used 1995 3.4 engine swapped into my 1985 Firebird using the 1985 induction (use 1995 3.4 injectors)/ignition system (Accel coil, Accel 8.8 wires, Bosch Plat plugs for a `95 3.4 mill, rebuilt distributor, now about 15,000 mile timing chain), 1995 "used for 50,000 miles" AC Delco Cat Convertor gave the following readings.
I can't believe the readings from this drivetrain.

The testing speed is at 15 MPH for these figures:
RPM is 1870

%CO2
MY Firebird 14.4

%02
MY Firebird 0.7

HC (PPM)
Max 130, Avg. 41
MY Firebird 11

CO (%)
Max 0.81, Avg. 0.13
MY Firebird 0.00!

NO (PPM)
Max 1115, Avg. 399
MY Firebird 147
I passed this part!

This part is 25 MPH & RPM is @1820

%CO2
MY Firebird 14.6

%02
MY Firebird 0.5

HC (PPM)
Max 105, Avg. 29
MY Firebird 6

CO%
Max. 0.61, Avg. 0.11
MY Firebird 0.03

NO (PPM)
Max. 945, Avg. 332
MY Firebird 192

Again I passed this part.
I was informed my timing at 15
Yet it registered at 10.5 last smog test two years ago!
He disconnected the timing advance plug at distributor for the higher reading, yet inserted 13 (max allowed) and passed me!

I am still stunned my car runs this clean!
And is as powerful as it is.
Best thing I ever did was blow up the original 2.8 engine and insert a used low milage 3.4 mill followed by a fresh tranny rebuild.

Happy Motoring, Says Jennifer!

 

Forgot to add the pic!

 

:sillylol: LOL, when I read the tittle I was like hmmmmmmmmm this could be interesting
Low and behold it was, congrats on passing the smog test.
I'm lucky that I dont have to test cause I'm runnin richer than a city bank.

 

if i had to take emmisions, i would move. :sillylol:

 

does she feel violated?


I should be having mine violated OH style in a month or two

 

Congrats!!!

I know my s10 runs cleaner, even without the vss hooked up.

Not sure about the camaro.

Time to have that blazer tested karl

 

I just take mine to the test facility and she passes without doing a single thing to her. And more or less with flying colours too.

 

What are these... 'smog tests' you guys speak of?

(yes, that was a joke - gotta love the Sunshine State!)

 

hey, I don't really need an e-check, unless I don't want to drive the car on base, which is where I'm living now

 

lets get this right your running 3.4 liter injectors on a 2.8 ecm ? is this a TBI or MPFI setup and which engine are the injectors stock to ?

also its amazing what a good quality cat can do to emissions.

 

yup, stock 85 ecm, stock 3.4 injectors on 3.4 engine, MPFI setup.

 

For christs sake Karl, that car is still under age! Next you'll start drugging Jeniffer and have to change your screen name to Luster.

 

:sillylol:

Let me help ya understand better.

What I do is buy a used running 3.4 long block from the only soucre, a F Body from 1993-95.

This option/purchase includes the 3.4 induction system.

I remove the 3.4 induction system, COMPLETELY.
I place the COMPLETE 2.8 induction system onto the 3.4 long block.
USING THE 1985 2.8 FUEL RAIL, I REMOVE the ORIGINAL 2.8 injectors.
I substitute/insert the 3.4 injectors, continue assembling the 2.8 induction system onto the 3.4 long block.

Think of "increasing jet size on a carb" due to more engine power needs.

The 2.8 fuel injectors are a "pintle style" and flow less fuel needed for the 3.4.
The 3.4 fuel injector have an injector head that looks like a "shower head" and also flows more fuel for the larger engine.
Simple!

PLUS
no need to SWAP ANY ELECTRONICS AS
you are using the ORIGINAL VEHICLE 1985 SENSORS SYSTEM placed onto the 3.4 long block.
THUS everything is beautiful, in it's own way......

Really, the beauty of the 2.8->3.4 Long Block Swap Boogie is that ya already own all the stuff ya need to swap into your car.
Only need buy the used running long block, a full engine rebuild gasket kit for THE ORIGINAL YEAR VEHCILE engine and a new timing chain and water pump. Then get to work.

Again, this is the second CA smog test I have done with this swap. I can't recall when I changed plugs or did a tune up. Proabably after the swap was completed. I didn't even change the oil & it's due at 3,000 miles from last time.

This 2.8/3.1->3.4 swap is a total WIN/WIN for anyone who reads this.

The engine pic may look boring, but, works great on the road! Yes, I replaced and used original 2.8 air cleaner set up for smog tests purpose. This is my Hokey Air Cleaner.

 

AC Delco CC I use is from the 1995 3.4 engine I installed into my Blazer.
It is a used 50,000 mile item.
Sized 2 1/2" in & 2 1/2" out (shows the NECESSARY upgraded factory exhaust used on 1993-95 3.4 F body!).
I looked at it, inside too, & looks brand new. I could literally see right thru it!
When I dropped on the floor, the already replaced/aftermarket CC previously on the Firebird, chunks fell out of it!
After I installed the AC Delco CC, my exhaust also had a nicer TONE, exhaust note.

AC Delco does produce many exceptional products. I got lucky when I asked for the "Y" pipe to be included with the 3.4 for the Blazer swap.
