EGR removal
 

I have an 90 turbo and I am looking to remove the whole egr system. What all do i need to take off/cap etc. and will i run into any problem doing this. I think I know mainly what to remove but i want to be sure i get everything. If you could tell me where things are located to save me some time with the tsrm that would be great too. Thanks!

If you ever need to smog test the car, you will need the EGR in place.

Tell us the story behind this.

WHY do YOU feel you need to remove it??

I live in Wisconsin so i dont need to smog test. I want to clean up the engine bay and i dont like the idea of all that going back into my motor. It is also one more thing that can go wrong down the road. I dont feel like i need to at all i just want to get rid of it reduce clutter, vacuum lines etc. I just took the egr caps off a jdm 7m i have and then im going to cap the vacuum lines.

he does have a point, i have heard alot of you guys telling me to check my EGR valve because it might be stuck open or somthing along those lines, getting rid of it would fix that problem, hell id get rid of it if i knew how to

i would love to remove the EGR, but i live in CALI and all the tree hugging hippies out here would rape me..


egr is the stupidest thing on the vehicle.. re-routes exhaust gas into the intake to reduce emissions and power. hot air intake FTL

so then how would us guys who dont have to do emmisons remove this EGR crap, yea i know damn them tree hugging bastards :) im plannin on movin to cali haha. they'll love me down there. although my car will be registered still down here in washington so i dont think ill have to.

well i did some searchese this is what i found

7mgte removal of charcoal canister and EGR

Now remove the vacuum hoses that are highlighted in red. And cap off the vacuum ports that I highlighted in green. That’s all there is to it for a stock setup.

as for the blocking off i was reading a little more on this, if i got this right the right red circle you want blocked off. but as for the right one you dont want to block off, the 2nd block off goes onto the intake plenum heres a pic of that

Same thing as before. Red are the vacuum lines you can remove and the green is the places to cap. And the blue dots are pieces that you can remove.

"NOTE"
i got all this information from other peoples post, so dont try to think im smart :)

this type of things makes me glad i took my egr b4 i put the engine back,
cuz its pretty hard to get tools back there
or maybe im jus clumsy like that

Thanks a lot guys i'm definately capping those when i put my head back on. The visual was a big help. I was lucky i had a jdm engine with the block off plates sitting around that i could "borrow". I agree egr worst idea ever.

Dont forget to cap the bvsv on the water neck too.

Don't ditch the charcoal canister, if anything replace it with a smaller one from a newer vehicle. It gives the gas that would other evaporate out of your tank somewhere to go until it can be used by the engine.

As for the EGR removal, if you're doing for looks, fine. But it also helps reduce your combustion temps and has been proven on the dyno to make no noticeable performance difference whatsoever.

where is that located at?

The bvsv is part of the charcoal canister's system (evaporative emmissions control). You don't need to remove that or the charcoal canister unless you like gasoline vapor in you engine bay or just evaporating out of your tank. Dunno about you, but i'm dead set on burning every 10th of a cent worth of gas I buy these days... a few years ago I may have felt differently.

It is on the thermostat housing it has two vacuum fittings coming off of it

I got a 1989 Supra because my friend wouldn't pay me back. It had a blown head gasket when he got it. He did that work himself, I'm a little worried about that, haha. But he also did the egr/canister delete.. As well as he got rid of the 25719 tank "vacuum surge" with maybe a few other things.. I don't know if those can be taken out or not? And if not, will that stop the car from running/starting?

Sounds like a bunch of people have no idea how the EGR works or what it actually does. :dunno:

Cre is correct, it serves a valid purpose and does not adversely effect performance in any meaningful way. Unless of course you're relying on the data from your ass dyno.

CORRECT - Personally I do delete the connections at BVSV & just run Vac line fm Evap Can direct to Vac Port on Intake.
