OK-so maybe all facts are pointing at a stock 3.8 "SHOULD KEEP THE EGR".

But an I/C would be doing the same thing then-lowering intake temp.

N/M with the cooler air combustion temps will go up-that makes sense.

But if the car can breath propperly and PCM is tuned to run such items or deletes then there shouldnt be any problems-RIGHT?

Say hypothetically you have a cam. the cam helps keep the combustion chamber cooler-so with the right cam your combustution temps will reach a certain point and stay there.

IMHO-there are a lot of ways to get past the EGR removal and still keep the combution temps lower. Cam -rockers-PCM work-and so on. And still NOT burn a valve.


BUT on a stock 3.8=KEEP THE EGR! I can see that, that makes sense now.

Yeah thats what i'm reading in to it too. If its stock then the temps will eat the valves, but open it up and your good to go?

It'll run hotter, but your 180 stat will help a little. EGR helps emissions too.

And as stated in this thread over and over, if you don't run it, you will burn valves.

Well at least MOST will agree on this that the STOCK 3.8 NEEDS an EGR!

As to the intercooler, well in theory, an EGR would be redundant. This IS assuming that some work has been done too (better valves & pistons).

Not much concern for the environment in this thread.

The higher combustion temperatures in your engine caused by removing the EGR cause more NOx to be produced.

NOx is a precursor for ground-level ozone, and that'* bad for your health. That'* why the government has mandated emission controls on all automobiles in this country.

http://www.in.gov/idem/air/smog/o3ed/index.html

Unfortunately, people don't give a **** about the environment or don't know any better, that'* why emissions testing is mandated for cars in areas with ground level ozone problems.

It comes down to 2 things:

1. Caring for the environment
2. Caring for the health of your valvetrain

If you care about neither, ditch the EGR. If you care about either or both, keep it.

Hard headed hot rodder sez:

pulled the EGR off the '93 today... if it burns a valve (which it WON'T) I'll let y'all know

I'll second that.
By the time my valves burn I'll be about 90 years old based on the mileage I put on. :P
My 25 year old Firebird, sans EGR and all emissions devices, only has 80 K miles on it.
