How-To: Primary EGR Delete

[SpeedRebirth]

Plan on installing big turbo in the future? Or just want more space for your wrenching moments? Then you might consider removing the EGR Valve!
If you already know how to remove turbo Intake and Battery, please proceed to Section 2.


Section 1: Battery & Intake removal

Section 2: EGR Valve removal and installation

Section 3: Alternative coolant hose

Section 4: Disable DTCs

Kozmic Primary EGR Delete. Buy it from edgeautosport: Primary EGR Delete
Use some sealing tape on the threads of the copper fitting to avoid leakage







================================================== ===========================
Section 1: Battery and Intake removal


Here we can see where the EGR Valve is located, right behind the fuel pump.
To get access to it we'll need to remove the battery and intake.




Unhock MAF cable from MAF housing using a flat screwdriver




Remove SRI from turbo inlet (10mm)




Remove Bypass Valve Hose




Remove hose that connects inlet to valve cover




Disconnect turbo inlet from bracket (10mm)




Remove vacuum hose from inlet, then loosen the clamp that holds inlet to the turbo using 10mm socket and long extensions. Remove TIP!



Now you can proceed to removing the EGR Valve












================================================== ===========================

Section 2: EGR Valve Removal





Remove the electrical connection on the egr unit, and then the black boost controler connection behind the egr.
This will free up alot of space and enables you to move the big harness out of the way.




Remove clamp and use a screw driver to push the hose out a little bit. Dont disconnect it yet!




Use a ratchet and a 10mm socket to get the first screw out. Put some rags under the egr unit to catch some of the coolant that will flow out when removing the hose in next step




Remove the hose from egr unit and quickly move to the next step




Get the 10mm socket onto the second bolt holding the egr unit




EGR removed!! The gasket has some tabs on the sides so it will most likely stay in place




Removing this lump of metal and plastic just made your car a little bit faster by saving some weight




Get the delete plate in place and use a 14mm socket to get it tight. Connect hose to the barbed fitting




The hose might be too short, as it was for me. If it is, go to Section 3 to make your own from the throttle body coolant hose.
This is how crocked my hose was, not good enought!




Look how much space we will have when installing a bigger turbo













================================================== ===========================

Section 3: Alternative coolant hose

This is a alternative way to get the coolant hose to correctly connect between egr plate and coolant hardline on turbo unless you have a different hose available.
This requires two caps to put on the nipples on the throttel body, you dont want dirt in there if you for some reason would reconnect the hoses later.
By using the coolant lines connected to the throttle body you get a longer hose to play with to avoid it from bending to much.


Start by removing the hoses that's connected to the throttle body and put caps on the nipples (these caps are from JBR's coolant bypass kit)





Remove the hose that was connected to the big aluminium coolant hardline. Looks like this. You will need to cut this to proper length when installing it onto the egr plate. I used the right side of it




Connect the other hose to the aluminium coolant hardline to make the coolant circulate




Here is my hose, there is still a bit of a fold in the line, but much better than before
The barbed fitting exapandes the hose a bit so i could not get the clip on. So i used it to make the hose round (hose was folding where the clip is in this picture)


I ziptied the hose on the egr fitting to make it snug!








================================================== ===========================
Section 4: Disable DTCs
You will get a CEL or two when the EGR Valve is disconnected.
They are: P0403 and P0401

Use Accessport or Versatuner to delete them!
In VT you go here: Home > Settings > "Edit Tune Customizer Profile" > Disabling DTCs > Advanced





Congratz! You are done! Finished! Fatto! Klar! Completar!

Nice detailed write up!

[dereeek]

nice write up. I have this sitting in my garage right now.

How much coolant came out when you took the egr off?

[SpeedRebirth]

First 30secs there was not that much coming out, after that it started to flow a bit more. How much that is lost depends alot on how much time it takes you to get the hose onto the fittings. Took alot of time for me because i didnt have a solution for the bent hose until i came up with the throttlebody idea. In the meantime i put the original egr hose back o

[Mazdazilla6]

If you want to keep your throttle body hose you can stop at a local hardware store and pick up some high temp gas hose. It should work just fine and won't collapse like the stock one did.

nice write up, but, is there a secondary egr we don't know about?

"Secondary" EGR is the EGR pipe.

[SpeedRebirth]

There are probably alot of other hoses out there that can do the job just as good or better.

Secondary is like monkey said, the hardpipe thats connected to the intake mani.
Secondary EGR Plug > Secondary EGR Plate > Primary EGR Plate


I belive its even possible to delete the aluminum thats bolted to the block, think i saw that i someones thread. But i think that included some welding and rerouting of the big coolant hose that goes to the radiator. May be a bit much =)

[Tokay444]

ah.

[kritz]

Nice write up and photoz.

[Tokay444]

i like my egr.

[darkstar5440]

I just got one of these due to the way precision turbos fit, it is needed. Thanks for the write up!

Are you blocking off the coolant ports or are you mating them together?

[SilverMS307]

@SpeedRebirth; Did you have any problem with it leaking out the bottom after? I reused the gasket and it's still got a very small leak. I tightened the fuck out of the bolts too.

Its leaking coolant?
I have not seen any coolant leak. But my AFR's are very rich but that looks to be the BPV gasket. So i dont think i have any leak at the EGR unit.
I just bought a papergasket that will allow me to make my own gaskets. But the egr gasket need to be of a different material to withstand coolant and exhaust gases. If you find a good material, its pretty easy to make a gasket

Just bought the new Atmosphere turbo kit so we'll see if it everything stays leakfree

[SilverMS307]

Yeah it might be excess leaking for now. I'll just keep an eye on it for the next few days. When are you putting that kit on?

[SpeedRebirth]

Just payed for it, and i live on the other side of the atlantic so it might be a few months hehe.

Great write up! Thank you for the help.

who makes your egr plate?

The primary plate is from Kozmic and the secondary is from JBR. Edge has them both

[ms6_604]

May I just say after a long day fiddling around, wrecked back and fucked up hands from all the twisting turning and unscrewing parts in epically tight spaces, it's finally done my EGR valve is clean as fuck, if that thing dares to throw an ECL I'm going to delete that thing like it never existed. Thank you for the thread and one who posted it, big respect!

Amazing write up. Thank you!

Thanks for the extremely thorough how-to!

So I understand that with the ap one can delete the dtc but will the car pass emissions with the codes just deleted? And if it doesn’t does anyone make a resistor mod to trick the emu to thinking it’s on the car still?

Exactly like it was explained to you on your personal post, it just doesn't work this way....It is no longer an ecu that just look for a working load that can be simulated with a fixed resistor.

Removing a code with the AP just isolate it from triggering the CEL light. The emission test will remain incomplete for that part unless a working EGR valve is operating on the car for xxx driving conditions monitored.

[pluckdawg]

where do the throttle body hoses go? I know one goes to the hardline going to the oil cooler, but I can't find the other one anywhere.

[Jeff23spl]

i think mine was going to the cooling elbow behind the tih
