Well i finally have time to sit down and type out the how to on blocking you egr gases from entering your intake manifold. thus cooling the intake charge and keeping your engine internals cleaner. And along with taking the EGR pipe that blocks the flow of air inside intake manfiold removing it will give you more airflow and less disturbance. The car is noticeably more responsive after this mod.
I searched around all of the internet , posted quesitons here and found no info what so ever and mean zero info for the 2jz-ge egr mod as it basically didnt exist . So I decided to do this write-up for fellow Supra owner's after i figured it out.
The 3 things you need to do this mod is 2 expansion plugs from pep boys,
part# 362501.1 35/64" sc exp plug
part#362747.1 20mm deep exp plug
Can of intake/thorttle body cleaner- you will see how dirty is when its apart. it took me almost 2 cans to get everything clean
one fuse from radio shack
ohm 1/2 watt resistor (part# 271-1126)
use the same resistor as the twin turbo egr mod
Ok lets start at step one .
step #1 Remove you intake/ intake pipe and filter
step #2 disconnect all the lines going to your throttle body
inlcuding thorttle lines and vacuum hoses. make sure you note what your removing and make sure you know where you took it off when putting evrything back when your done. there a egr diagram under the hood to help you out.
step #3 disconnect the egr system tubes and remove the tope egr saucer looking thing.
Step #4 removal the throttle body make sure you removal all the bolts.
Step #5 diconnect any tubes going into your intake manfiold.
Step #6 removal all the bolts holding the intake manfiold which is right after the throttle body and lookis like a y its one tube going into two then it connects to your runners. The inatke manifold uses a metal gasket and can be reused just make sure you dont damage it when removing it. Ther are going to be two bolts under the intake manfiold so you have to take them off before you take the manfiold off.
Step #7 remove the egr tube that attaches to the intake manfiold . you will need to take the bols off ten reomal the threaded bolts that hold evrything together/
Step #8 ok now you have done the hard part / you have the thorttle body off, you ave the intake manifold and metall gasket off .
Step #9 unplug the egr probe sensor connector and put the fuse in where the egr probe plugged in. make sure you secure the fuse in there. this will disbale your check engine from coming on.
Step #10 Clean the inside of you intake manfiold until its looks new. when you look inside the intake manfiold you will see a metal tube right before where the single intake path becomes two and right before the sort of air foil thing. thats what we called it on the impala's. Anyways you will need to unscrew the screw that holding the pipe in . next drill a hold threw the expansiong plugs that in there and take it out .
Step #11 removal the pipe that goes threw your intake manfiold thats used for the egr. its going to take you a couple mins to do . its snug in there. but it does come out.
Step #12 install the new 35/64 sc exp plug in the place of the one you took out.
step #13 install 20mm deep exp plug in where the egr tube connected to on the side of the intake manfiold . this will block the hot /dirty gas from entering your engine.
step #14 Now you are ready to bolt evrthing back on the car . its easier to put eveything back on then it is to take it off. Now just reinatsll all these parts on your car . when connecting the egr tube that comes from the back of the block back on the car make
sure to use the gasket. reinstall all the vacuum tubes/ sensors, install the throttle body , reconnect all the vacuum hoses and throttle cable, make sure everything is in the right spot. or else your car willnt run right. install you intake reonnect the maf, and start her up. It might take couple mins to idle right but afetr that your set. it took me about 5mins cause i disconnected the battery and cleaned the runners with intake/throttle body cleaner. the engine was really dirt on the inside. if you look at the egr tube you took out you will see how much crap is in it.
By the way your car might not pass emissions with this mod but ifs its already warm and runnning mint you will. If this is a problem for you dont do this mod is (off-road use only)
Good luck Sorry If i left anything out .

If you want to take the whole egr system out you will need two egr plates to remove it completely. this will clean up your enigne bay but its emission legality is questionable but alot of cars pass visiaul with it blocked and should pass if the car is running good and is already warm. I am in no way repsonsible for anything that occurs after this modification to your car . Sorry i just have to cover my A$$. I have done this on my car within the last week and the car is alot more repsonive . it pulls harder and no affect on gas milage or idle.
i have seen no downside with it as of yet except a more responsive car. its like porting you intake manfiold to a degree you now adding about 20-25 percent more flow internally. so if you have a exhuast you will see a bigger gain. the gain is from removing the pipe. blocking the egr basically
stop the overheating of your pistons and wot and keeps the dirty gases out of enigne . All the tools you need are the same as the twin turbo egr removal . Sorry i didnt have time to note what sockets i used . Enjoy
