Guest TurboSedan Posted October 20, 2006 Report Share Posted October 20, 2006 i finally got rid of the EGR 100% i didn't use a blockoff plate. i drilled out the EGR passage in the plenum and tapped it for 1/2" NPT and installed a brass plug. the 3 mounting holes unfortunately go straight through (they aren't blind holes) so i bought some M10x1.25 allen head set screws and screwed them in (with thread tape of course). you can see that i cut off the vacuum line that previously went to the EGR and capped it (yellow cap): i also took my crossover pipe to the local exhaust shop and had them completely remove the EGR bung and weld it up. the bung used to stick down into the pipe about 3/8" so if anything it even helped exhaust flow....even if only a tiny bit: Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted October 21, 2006 Report Share Posted October 21, 2006 Nice! did you put like any teflon tape or anything on the brass fitting to prevent any leaks? How come you just didnt use a plate? Woulda been quicker.. Quote Link to comment Share on other sites More sharing options...

How come you just didnt use a plate? Woulda been quicker.. i used plenty of teflon tape on the 1/2" NPT fitting and the set screws. i didn't want to fab up a plate and i also wanted to tap the manifold there anyway so i could add a 6-port McMaster-Carr manifold distribution block there later.

19Cutlass94 Posted October 21, 2006 Report Share Posted October 21, 2006 on a side note, that looks like one hell of a clean plenum! Well I guess if your going to add that, thene it makes sense! Quote Link to comment Share on other sites More sharing options...

19GT92 Posted October 22, 2006 Report Share Posted October 22, 2006 can this be done on a n/a 3.1 and are the egr's the same and does it run better with out the egr........ Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted October 22, 2006 Report Share Posted October 22, 2006 can this be done on a n/a 3.1 and are the egr's the same and does it run better with out the egr........ Yes, this can be done. The EGR on your 1992 is a digital EGR, whereas the one on Josh's turbo Cutlass was vacuum. You just wont have to block off the vacuum line like he had to. However, if you dont have EGR disabled in the chip you'll get and SES light. There wont be any difference except the upper and lower intake will be cleaner.

AWeb80 Posted October 22, 2006 Report Share Posted October 22, 2006 EGR's help w/ Gas mileage too.... Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted October 23, 2006 Report Share Posted October 23, 2006 ^^ Indeed they do, so youll be getting worse gas mileage if you do this... how much I duno and Im sure its not by a whole lot either... But for basically no power gain.. I think Id take the gas mileage Quote Link to comment Share on other sites More sharing options...

But for basically no power gain.. I think Id take the gas mileage It also keeps your intake clean and somewhat free of carbon. actually, like Robby mentioned not having the EGR there will keep the intake cleaner since no exhaust gas would be flowing through the intake anymore. What the hell is a 6-port McMaster-Carr manifold distribution block? it's a block that attatches to the intake manifold and has ports on it that can be used to source things like MAP sensor, FPR, boost/vacuum gauge, BOV, boost controller, and even hobbs switches to activate things like extra injector(s) or alcohol injection setups. here are a few pics of the McMaster-Carr manifold distribution block on my GTS: http://www.turbosedan.com/lebaron/DSC01560.JPG http://www.turbosedan.com/lebaron/DSC01561.JPG Quote Link to comment Share on other sites More sharing options...

I'm not that dumb! That distribution block is pretty cool, so its pretty much heavily modded cars? Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted October 23, 2006 Report Share Posted October 23, 2006 I meant that with it off it keeps your intake clean. I'm not that dumb! lol sorry i read your post wrong then haha. That distribution block is pretty cool, so its pretty much heavily modded cars? i mainly did it to my GTS so simplify everything and make it more reliable. the factory vacuum harness on a TD is ridiculous and prone to cracking (TONS of hard plastic lines going everywhere). i wanted to do it to my Cutlass for pretty much the same reasons - simplicity and reliabliity but also to add more sources of course. on a side note, my GTS didn't even have EGR from the factory, so i just used the hole in the intake manifold that the factory vacuum harness was sourced from. removing the EGR on the Cutlass just provided an ideal location for the vacuum block. now that i'm selling the car i won't be adding one, but i still think Dan should. the blocks are only like $15 from McMaster-Carr. i know Dan is going to add a boost gauge and that woud be the best place to route the line for it.

Guest TurboSedan Posted October 24, 2006 Report Share Posted October 24, 2006 i followed patgizz's advice (on 60*V6 forum) and took the allen head set screws back out, removed the thread tape and coated the threads in JB Weld and put them back in. that should definately seal better with no chance of boost pressure pushing them out. the thread tape just didn't hold them in there tight enough.

Puggsley456 Posted October 27, 2006 Report Share Posted October 27, 2006 Has anyone who pulled egr noticed a difference in highway gas mileage? Mine isnt removed, just blocked off.....and I noticed a big difference in gas mileage. Is there a way to disable the egr on the chip if its the electronic egr?

KCFITZ78 Posted October 27, 2006 Report Share Posted October 27, 2006 I have a 1994 grand prix se, 3100 SFI with what i think is a digital EGR. I think this EGR is giving me problems and was going to try and just replace it. If i can remove it from the engine this will help let me know if its the EGR that is giving me the problem. So my question is what all needs done to remove it: -How do you disable the EGR on the chip if its the electronic? -What holes need pluged? -How do you plug these holes? -Plug vaccum Lines? -Etc......... This would be a good write up! Quote Link to comment Share on other sites More sharing options...
