3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
What does everyone think of deleting the EGR. Will there be performance gains? Will there be a gas mileage decrease/increase? Will it throw CELs? I know on other motors it is considered a performance modification, and I know it will not pass emissions, but I don't have to do emissions testing (know a smog tech).
Motor: 1MZFE, but im assuming will have the same effect on other motors.

The newer 1mz don;t have an egr as the engine is rated as a low emission engine. I confess I don;t know which years or anything more than not all 1mzs come with egr.
As for performance you wont see any gains, the ecu closes the egr valve when the throttle position sensor registers wide open. EGR is useful during part throttle operation and constant speed/throttle cruising.
I wouldn't delete it unless your intake is particularly filthy from it, but the 1mz runs a lot cleaner than some of the older engines like the 3vz and older 5s-fes.
It will throw a cel without some way to make the computer think the egr is still functioning.

alot of the guys i know of that have deleted it are FIed, its another roadblock easily gotten out of the way by removing it. i cant see how, na, it will really increase hp...at least not enough to warrant taking it off. IIRC, all it does is recycle some inert gas into the intake system to reduce emissions. and yes i need one.
I have the 3vz-fe. I removed my EGR about 4 years ago. It improved the low end and mid acceleration, but mostly noticed better fuel mileage. An EGR valve allows some exhaust from the engine to be re-circulated into the intake, sure, it reduces NO2X in the exhaust gas, but think about it......It does for the engine, what putting a hose in your ass, farting, and sucking it in would do for you.....I think both could be happier without! XD
I was under the presumption that the EGR valve actually increases gas mileage??
EGR decreases gas mileage. Exhaust gas takes up some of the space in the combustion chamber, when the valve opens, that would normally be filled with clean air. this causes a lower efficient burn of the fuel by reducing oxygen content, lower oxygen content means lower combustion temps, lower combustion temps=less NO2X. It decreases overall efficiency of the engine. Remember, emission systems are in place to reduce overall negative impact on the environment, in the case of the EGR system-its main purpose is to reduce Nitrogen Dioxide in the exhaust, even at the sacrifice of a little more fuel in the process.
so, on the 1mz...??? keep it as long as im not FIed? P.S. Motor is out of the car, so its not like I would be doing work to remove it, i would just block it off and be done.

On gasoline engines EGR increases fuel economy during cruise situations, but only mildly so and removing it really wont hurt anything. The Japanese domestic engines never had EGR, it was only added for US operation so there are plenty out there without it.

it makes a bigger differance on the 3vz then the 1mz motors ive seen. its not a big deal to remove...even with the engine in. its a simple block off plate and resistor to trick the car into thinking its fine. slights increase in millage and power or slightly cleaner car for old mother earth. the biggest this is that ya may have to replace it to pass emissions.
I'm no tree hugging hippie, but I'm personally not a fan of removing EGR or Cats for performance increases considering the significant increase in emissions. But that's just me.

Will there be any visible effects from removing the EGR? such as increased tail smoke etc?
My car is an 92, i'm up for an emissions test on February. According to Ontario (Canada) law cars that are over 18 year old do not require an emissions test.
So i'm going to get my emissions done and then try blocking the EGR!
