EGR block off!
 

well when i got my new intake all of the hses and stuff that were conected to the stock air box are all just hanging there now, i have nothing goint to my header from the airboxany more, so how do i do an EGR block off ?

RE: EGR block off!
 

Go to the 3SX website.

RE: EGR block off!
 

and i am looking for?

RE: EGR block off!
 

just buy a block off plate off SBR or extreme psi or something

RE: EGR block off!
 

Yup, a block off plate and plugs for the hg nipples on the TB and the mid sized one that goes to the intake pipe. I might suggest a gasket for the blockoff plate too, I had a tiny leak from my blockoff plate and I used an old piece of tin to sub as a gasket...it's still working btw. Even an old or new, lol, soda can will work (assuming you do know that I mean to cut it to shape).
Might I suggest FFWD Connection.

They have a copper plate for just this reason
I have an aluminum one btw ;), hence my suggestion.

Hey VR4GARY, bud660r has an Eclipse...I'm just saying:)
Although this middle one looks like ours.

RE: EGR block off!
 

thanks alot for the clear answer silvercoupe!

it just a plate right nothing special about it? if so i could just make one out of alum "i work at a machine shop" we have alot of aluminum layin around!

RE: EGR block off!
 

Yup, any will work, just make sure that it's flat and you're good to go. :)

RE: EGR block off!
 

is there any benifits to doing the egr block off? or is it just to get rid of all that crap from the stock intake!

RE: EGR block off!
 

..that and a cleaner manifold+ and less gas milage (differs from car to car). I've got a nice big opening where my battery and EGR used to be :D

RE: EGR block off!
 

How much worse gas mialage?

RE: EGR block off!
 

does any one have a accual size pic of the egr plate! so i can trace it out and cut it with out dissmantaling my car:)

thanks for all the help! ya how bad of gass milage!
"not like it really matter's, it will still get better milage than a V8" lol:D

RE: EGR block off!
 

Yea im gonna make my own. Lucky me, new hampshire tests emmissions on cars 1996 and newer.....im 1995.lol as long as i stay over 20mpg im happy

RE: EGR block off!
 

nice!

RE: EGR block off!
 

if i had a template, like with measurements, i could get some made out of sheet type aluminum tomorrow for like $1 each.

RE: EGR block off!
 

I'm not sure on the actual milage, but mine went down about 20miles per full tank.

RE: EGR block off!
 

Thats about 1.5mpg. So no big deal really

RE: EGR block off!
 

ya i am going to make my own to i have some 1/2 inch maybe a little thiner aluminum! so it will be nice and thick and durable!

"thats what she said to me at least" lol

RE: EGR block off!
 

It is when you can't help but boost to every light, lol. Your milage shouldn't drop to the point where you would want it back on anyway.

RE: EGR block off!
 

does one of the block of plates bolt to the block it's self, i was just looking at it last night and was not sure if i remove all of the metal tubing thats there!

RE: EGR block off!
 

Yea, buying a block off plate is pretty retarded.

RE: EGR block off!
 

why is it retarded

RE: EGR block off!
 

its retarded because
1)it raises combustion temps, thereby causing pinging
2)you loose milage
3)you increase emissions.


basically, you gain absolutly NOTHING by eliminating it. Its not functioning at idle or WOT anyway, so the excuse people use about "gaining power" is utter nonsense.

RE: EGR block off!
 

Agreed. You gain nothing AND it's so easy to make your own. Buying one is retarded as well as USING one.

RE: EGR block off!
 

i am not looking to gain power i just want to lose all of the **** thats just hanging under my intake!

RE: EGR block off!
 

Correct, removing the EGR will do what you stated Manybrews.
What does happen when you remove it is, you remove any chance of vacuum leaks, you stop recirculating carbon, and that's one less thing to fail in a DSM.
I agree that it doesn't add HP, I never believed that either. What does that do for HP? You don't add HP, you only regain what was already there when you remove the EGR and Seafoam your motor. Raising engine temps, sure, but there are other things that will help lower it if you're really that concerned with it, but your engine temps don't go up enough to worry about melting things or knocking. Ping, is something you say about N/A cars, knock is what you mean I believe, Manybrews. That can be countered also, I've got alky injection on the boards as my next mod. That will help lower knock and raise my octane (that in turn will lower knock even more, which I don't have anyway). Gas milage? If I was that worried about it, I'd have a Toyota hybrid and not a 50-75lbs heavier than a GSX Avenger with GSX parts. Most DSM owners feel the same way, if they didn't, they would be buying bigger injectors and turbos, IMO.

If any of you get a chance, take the EGR valve off and scrape it with a piece of wood, a stick. Measure how many MM of carbon you just scraped off, now imagine that throughout the EGR's route. How much does a new EGR system cost? What does that do for HP? You don't add HP, you only regain what was already there when you remove the EGR and Seafoam your motor.

This thing gets really clogged up, it's about $88.

..but anyway, there's counters to both sides.

Here's some good reading about the EGR system and where the myths were first told.

RE: EGR block off!
 

so geting rid of it is no big deal!

also like i was asking before one of the plates bolt's to the block directly right?

RE: EGR block off!
 

It bolts to the intake manifold. The reason im getting rid of it is cuz im doing a 6 bolt swap and dont want to deal with the map sensor. If you are really THAT worried about combustion temps then get alky/water injection or just a better FMIC and you could even spray it with co2.

RE: EGR block off!
 

He said it would result in raised COMBUSTION temperatures, not engine temperatures. High combustion temperatures can result in pinging in any car as well as an increased amount of NOx emissions. Carbon is a byproduct of combustion- you'll have it in your engine with or without EGR.

J

RE: EGR block off!
 

You're right, but what happens when the combustion temps rise? Motor temps, not to mention engine bay temps will rise also...that's just a byproduct of heat in general, especialy in an engine bay. It's not localized in the combustion chambers.
Carbon is removed from the intake tract when the EGR is removed.
Of course carbon is still going to be in a combustion engine with or without the EGR.
Why does everyone try to keep folks from doing this? If you're worried about your air, petition the local tracks, hell, petition NASCAR!! Have the gov't take away old muscle car roaming around the streets of America, tell those bikers to get rid of their bikes, you know those big burly guys! Our motors will run fine with or without them, period. If guys don't want to take yours off or can't because of emission laws...don't, plain and simple. You guys crack me up.

Yes Bud66, the plate covers the hole on the side of the head that is left after you remove the EGR valve. There are usually two types of plates you can get too. One replaces the EGR valve and the other is used as a gasket but it's solid all the way through (except the bolt holes of course) and you retain the valve and you can also keep the EGR system intact.

RE: EGR block off!
 

THANK YOU! finaly someone gives me a strate answer

RE: EGR block off!
 

Not exactly- engine temperature, sucking in hot air, etcscan have an affect on combustion temperatures- but high combustion temperatures (lean mixtures, etc) may not not neccesarily affect engine operating temperatures.

I was merely supporting the statement from Manybrews and all that he said. You can do what you want with your car for all i care.

J

RE: EGR block off!
 

BOOM goes your engine.

RE: EGR block off!
 

You're looking too far into what you and I have stated and you're adding on terms, operating temps weren't stated earlier, only the combustion/motor/engine bay temps, until just then in your last post, but I guess we can add that on too.
Let me get this straight. What you've typed, looks to me like you're saying that if a motor runs lean, it's not going to generate more heat to raise engine temps, operating or other? Is that correct?
It sure would, with or without the EGR. As long as you know what you're doing, that's what tuning is for, to make sure it doesn't happen. My engine temps went up MAYBE 5 degrees, according to DSMLink after removing my EGR....does that warrant concern? Sure, if +5 degrees concerns you, but, No. Am I running leaner/richer without an EGR? No. Engine knock has not been affected, note that I also have an FMIC. I lost 20 miles from a full tank.
You guys make it sound like the EGR system dropps combustion temps down by 20 degrees or more, lol.

RE: EGR block off!
 

ok wow if some one can give me a simple answer PLEASE! is blocking off my egr going to blow my motor or cause any damege at all! or arepeople juts going crazy about this, i mind you this is a 420a eclipse that i am going to do this toso please tell me what is best!
i just want to get rid of all the hanging stuff thats below my short ram intake that isnt going eny where, you see i have new headers and i dont have eny of the egr stuff hooked up to it, so every thing that is conected to the egr system is just hanging there"besides the pipe that is bolted to the block and the intake mani!

RE: EGR block off!
 

no, you wont be able to raise engine temps by removing the EGR. the cooling system will be easily able to handle the added combustion temps. you will just suffer from a massive increase in NOX, and an overall lean situation until the fuels system catches up to the extra air supplied. then you will lose the milage, and probably trigger a fuel trim code (depending on the year of your car).
no, thats not right either. There is no "carbon" that is being recycled through your car. you are getting inert, combusted gasses assuming perfect combustion. Of course, this isnt a perfect world, and carbon is present in the fuel you're placing in your car. But that has actually underwent a chemical change after it was combusted as well, into CO and CO2 (as well as other wonderful chemicals). The carbon that shows up in your intake manifold regardless of EGR is mostly from evaporating fuel.
because its utterly stupid. You gain absolutly NOTHING. You loose milage, raise combustion temp, and pollute more.
I am always amazed at the way people try to re-engineer a well thought out car.
well, they are trying to take away the old muscle cars and they are placing the same emission standards on new motorcycles, but you're talking apples to oranges. There are what, 140 million cars in america? how many do you think are classic muscle cars out of that? less than 1 percent? and how many are driven daily to and from work?

why is it when someone voices that emission standards are a good thing, someone else comes along and thinks thats a sign of weakness by boasting how insignificant it is? look around.. our world is becoming more and more disgusting every year.
I just assume do my part to be socially responsable.

RE: EGR block off!
 

i know it wont blow up the 4g63. I know SOOOOO many people who do it.

RE: EGR block off!
 

egr drops combustion temps by many hundreds of degrees. it also slows combustion.
NOX forms when combustion temps hit about 2500 degrees, which is what the EGR was designed to reduce in the first place. Using inert gases from the EGR drops those temps immensely.
Contrary to popular belief, a properly operating EGR actually increases the efficiency of gasoline engines.

RE: EGR block off!
 

removing it will do what Ive already said.. raise emissions and combustion temps, whilst lower milage. Depending on the year, it will also trigger a "check engine" light, and if you live in state that has manditory emission testing, you will fail due to that.
not to mention thats its a federal law to not tamper with it.
but if you must have it "look good" under the hood for the once a month you open it, so be it. its your car. You will not "blow up" your engine.

RE: EGR block off!
 

I was merely being MORE specific differentiating the terms as they represent two completely different values.


That's exactly what i'm saying. Engine operating temps is based on coolant temperature readings- normally between the ranges of 180-220F. Combustion temperatures can reach over 2000F- anything over 2500F is considered NOx territory. You can easilymistakenlyrun super lean mixtures without affecting the cooling system. NOx combined with certain chemicals in the atmosphere results in Photochemical Smog. Photochemical Smog is the smog you can visibly see (ie, Los Angeles county with it's daily dark cloudy smog formation- see below).What do DON'T see is what is doing all the damage to the ozone. All EGR attempts to do is keep combustion temps below this temperature range.

RE: EGR block off!
 

Now that you have both sides Bud. You decide what you want to do.
Not every motor is the same, but removing mine was a neutral experience. I don't think I'm helping the ozone either because I'm usually in higher RPMs and boosting...whether high or low, I'm still boosting ;)...so the EGR would do my motor no good (and I'm an easy driver compared to the other Hawaii drivers). Yours may have an actual use if you use the interstate a lot.
