  • EGR block off plate.

    DOHC from a 1992 SC2, gonna be turbo...

    Good idea to scrap and block off the EGR valve? How thick/strong would the piece of metal neeed to be? Reuse the gasket?

    Just wanna do it right.

    Thanks.

      Thanks. For 14 bucks, better off not cheaping out.

        That is the one I have, a nice little piece. They have changed it a little, it looks nicer now.

          I went to home depot, and got this like kickplate that goes on the doors of your house, like on the big swing doors that lead into kitchens of restaurants. They had it in aluminum, or steel in a larger sheet for like $8, I took the gasket, traced it on there, and cut it out with some snips. Then put that on the gasket, then the egr valve over that. Ive also made radiator shrouds out of it as well, pretty sturdy.

            OK this may be a stupid question.

            But what advantage do you have from blocking off the EGR?

            And do you have to do anything with the connector that used to plug into the EGR or just leave it hanging in the engine compartment?

              unless you are running nitrous or some sort of f/i I don't believe there really is any benefit aside from the intake manifold staying cleaner longer.

              the egr only opens under part or wot, not both (I forget which one at the moment), so either way you won't have a huge benefit from blocking it off.

                A cheaper EGR block off plate is available at most intersections late at night if you own some nice sharp tin-snips...

                  Pretty much.

                  The EGR only will open

                  -At Cruise under partial throttle, constant speed.

                  The EGR is closed:

                  -At WOT
                  -Under increased load
                  -At idle
                  -when the engine is cold.

                    yeah thats what it was, thanks Nathan

                    I remember I think it was Jeremy who kept melting a plug until he plugged his, so most of our nitrous guys plug theirs as well.

                      Can't I use the vacuum hose from it for a boost gauge?

                        as long as the reference it uses is off the intake manifold you should be good to go

                          it goes to right in front of the throttle plate which is why the egr only opens at cruise/partial throttle
                          id find a better source
                          i used the vacuum line for the fpr for my vacuum guage

                            ok that would work fine then actually, no reason it wouldn't since it's right at the plate.

                            the main reason I dont' suggest people use the FPR line is you don't want a leak where the T is or at the gauge since it will alter your fuel delivery.
