removing egr and other junk.... need some help
now i know its been talked about in a few threads but i need to know for sure what the hell im removing or leaving in.
i just picked up a DI manifold and hypertune TB. i had the mani tapped for the map sensor ans the IAC is also all setup....
i have the egr disabled in ecuflash now with no lights but everything is still installed on the car with the stock manifold. my main question is what vacume lines i can remove and do i need to leave everything plugged in or can i ditch that stuff too.... i have read around but it seems to be more here say on what to do. or at least it apears to be. so maybe this can turn into a facts thread for others as well.
now these pics are from extra parts from somthing else but its still all evo stuff..
in this pic its a bunch of vacume lines and the egr valve. but do you see the red and black check like valve thingy. what is that and does it need to still be hooked up..
that check valve runs into the big hoes here on the intake manifold... i dont know where it goes once its behind the manifold
so what can i remove or unplug or throw out. haaha

This hose mentioned above routes back to the fuel pump. I think this can be removed and vent to atmosphere.

OK dudes, more info. The hose running back to the fuel pump is just for venting, just point that at the ground, zip tie it somewhere so it doesn't get stuck somewhere it shouldn't. Get an EGR Block-off plate (I got one off of ebay for $5 shipped, working great) AND make sure you use a NEW gasket when installing it (often doesn't come with one) so it seals good and tight.
After that, take all of those hoses and just put them in a box or file them in the trash bin filing cabinet. Use any of the extra ports and eliminate any T's you have spliced off of a line elsewhere, and then block off all of the other ports with vacuum caps. SAVE the solenoids, as you will throw a CEL w/o them. Just plug them in (the wiring) and then zip tie them out of the way somewhere.
Lastly, go to the ecuflash forum and do a simple search for 'EGR' and and you will find as part of one of mrfred's other posts (on installing JDM MAP sensor I believe) a tidbit on what to change to delete the EGR check from the ECU. It's periphery 2 or 4, don't recall off the top of my head.
Enjoy! I've been running this setup for about 6-8 months now.

I did this mod on my car with a Melocik Motorsports ported manifold and a Melocik Motorsports 65mm TB with Works seals and have had wonderful results! I am working on a step by step tutorial for a buddy of mine since he wants to do it also. I have a picture on my computer somewhere of what the inside of a stock manifold looks like after running the EGR for about 30k miles and what it looks like without it! Amazing difference!
+1 for a $5 block off plate. I made mine out of aluminum and it worked fine but for $5 it's not worth the hassle. Anyone have a link to those? Please post if you do.
Thanks
