I know this has been asked before and I have already searched forums for couple of hours.
And I know that this has been brought up many times and is not for everyone, but please bare with me, and please help

What do I have to do to remove my EGR system?

1.) I know that many people say not to remove it because of emissions
I don't have to pass emissions.

2.) it has been said that the EGR system has no affect on performance at WOT
I have read that on many technical websites and books involving the EGR system and 85-90% of what I have read says that there is no loss in performance because the engines computer advances the timing and A/F curves to make up for this difference- So,
2.a.if there were no EGR system to make up for wouldn't that extra HP be a gain, a very small one but none the lass again
2.b.If when the computer senses the EGR valve open the computer advances timing then the addition of more timing is the opposite of what I want with boost.

3.) The computer will throw a code

3.a.If I remove all components then the computer will not sense whaen the EGR is open and/or active- and basically think it is not on
3.b.also I have a SAFC-II and cannot control the EGR and it will therefore be an uncontrolled variable when adjusting A/F.--I also plan on getting the e-manage Ultimate soon and will have the same problem as the SAFC-II on the A/F as well as on the timing adjustments since neither has any EGR correction to counter-act the factory ECU's EGR corrections

4.) that still isn't reason enough

I want more room under the hood as long as just an overall cleaner look, I have already done alot of mods and replaced ALOT of the stock parts for aftermarket parts so even if I were worried about passing emission(which I'm not) I wouldn't pass anyway

If anything I said is incorrect please correct me....
So with that said can you guys help me?

I already have the intake manifold off(being P&P and Powder coated).
I know to remove the EGR valve itself, the tube that it goes to it, as well as the vacuum modulator, vacuum line, A vacuum switch(I don't know the name of this part), and plug vacuum ports on throttle body

What I don't know yet,
do I have to remove the charcoal canister?
can I just plug the tube that used to go into the EGR valve?
what other things that I did not mention that I have to do?

I think removing the EGR should be done for cleaning up the engine bay and removing vacuum lines that can go bad....but not for performance. Good luck.

once u remove the EGR, the car is probbally gonna spit out some soot while you drive. Although it does increase Performance 10HP or more. Its overall worth it. Some people will tell you that it doesn't do anything, but look at JDM engines and USDM engines.
JDM = no EGR --> More HP
USDM = EGR ---> Less HP
There both designed the same way but ones got more HP than the other cause of the EGR.

Waste of time Usually the difference between JDM cars and US cars is the lack cats...jdm cars also sometimes have different ecu's. The EGR system isnt going to give you any power...even if you lost or gain 3hp you would never know anyways...waste of time.

Exactly correct. The difference in the power of JDM engines is attributable to the ECU.

basically some of what I said on my 4th reason(s)

JDM and USDM engines are not designed exactly the same. There are usually differences in the ECU and exhaust system, bottom end internals and cam profiles.

So basically so far this is what I am removing

Air control valve
EGR vacuum modulator
EGR valve
EGR valve tubing
Vacuum switching valve

then I'm going to plug the throttle body where the vacuum lines to removed components were.

Also should I plug where the EGR valve's tube was?

Still don't know if the Charcoal canister can be removed?

[dlx742]

how are you going to plug those things up...

im going to remove mine too so i would just like to know how you plan on doing it

I believe you need the air control valve. I could be wrong.

I'm not 100%(mainly why I'm trying to get more info), but in my vacuum diagrams it is only connected to EGR system

I know for sure that there is an Idle Air Control Valve that does have to stay on the car but does not connect to EGR as far as I know--Could that be or is that what you are thinking of?

Seriously... NOT A PERFORMANCE MODIFICATION!!!! If you wanna remove something that can immediately affect the car's performance... lose weight.

egr can be removed or deactivated without any effects on performance or lifespan or whatever... it is a device only used for better/less emission!

Still don't know if the Charcoal canister can be removed?

that doesn't have anything to do with egr! it is part of the fuel system and used for filtering fuel gases from the tank! so better not remove that

I already have , I've already lost 20lbs. on myself and done weight reduction on car too!!!

so what does egr stand for?
