EGR block off plate

[98vtec]

you can take out your EVAP while your at it as well.

p06 is not wired for EGR, so it wouldnt be functional anyway. pitch it!


egr is an emissions system, not an essential system.

what about a p28

what about a p28

Doesnt look for EGR either but its extra money if you have a non vtec motor. If you have a vtec motor the price is justifiable. The p06 can also be converted to a p28.

disabling the EGR will reduce the heat in the CC. it is there for smog purposes but yes, a chipped ecu will rid the system for finding the egr.

maybe disabling, but not just blocking it off on an engine/ecu thats meant to have it.

when the computer opens the egr valve its substituting normal outside air with air that contains less oxygen in it and therefore requires less fuel to burn. just blocking that off will lean out the motor when it it "thinks" that the egr system is open and will actually cause it to run hotter. Maybe its not enough to hurt anything but you certainly are not gaining anything by blocking it off.

this is what i found. its intresting i just qoted him from another thread so hes no flamming nor am i. just though this was good info

I'm not going to be polite so sorry.

The egr does NOT increase combustions chamber temps...it does the EXACT opposite!

The egr REDUCES the combustion chamber temps guys...you should really learn about what your cars parts do before you start messing with them.

Taking it off will increase your risk of NOx and knocking.

It will not increase horsepower by any percent AT ALL.

The egr does not operate at WOT.

The egr does not operate at idle.

The egr ONLY operates when you are cruising at higher speeds.

It puts a minor amount of exhaust gas into the cylinder which reduces the combustible amount of gas...giving you a lessened bang...thus decreasing the temp.

This increases fuel economy.

But it only does this at idle...the INSTANT you raise your rpms...it stops doing this.

This is a pointless mod and not worth being done...so undo it...quit wasting your time with it.

Another pointless mod that I put in the same category as this is taking the vacuum line off the fuel pressure regulator. Make you dump excess fuel even at idle.

Please learn what you are doing before you do it...you are wasting your time and reducing your fuel economy.

The best advice for you on this...is undo it...and put it back the way it was. Even if your egr was clogged...get one off a junk yard and replace it...knocking is not cool.

Thanks for the quote. I do have to say though that was for an N/A motor...as to using on a turbo...I can't see how you would actually gain anything...it only operates under vacuum...so it shouldn't do anything during boost...but...I'm not fully versed on turbo tuning yet...

Any one with turbo exp. got thoughts?

I don't think taking off the egr would gain anything...even on a turbo build...but...I can't see it hurting anything taking it off for turbo build....I mean since you're running boost and are already going to take extra measures to keep combustion chamber temps down it might not matter...but again...I'm not turbo guru
