Egr?
 
Can I delete the EGR on my 00 without any terrible effects? I am going turbo and that would make things easier. I suppose that would cause a check engine light, but is there any way around that? I will be making my own JGS manifold, and tuning with e-manage just to give a little background.

You just remove the tube and block it off at the intake manifold. It won't cause any problems, most likely won't even cause a CEL. On my car the tube is cut in half, pinched shut, and brazed closed. Came that way but it's easier than making a new blockoff plate.

sweet, thanks.

So do you leave the tube connected at both ends, but just put a plate on the intake side to block it off? The benefit is you don't get the nasty exhaust gasses in the intake, but are there any downsides to this?

I left it connected on the intake side, the HKS manifold i'm using right now doesn't have an EGR port. The BEGI manifold i'll be using does have the port but i'm plugging the port.
Are you guys all interested in block off plates?

I guess the point to the blockoff plate is to leave it looking functional for an inspection?

The point to the blockoff plate is to not destroy the egr tube which can be sold for cash monies or swapped back on for inspection, or to just remove the EGR tube instead of crimping it up. The plate just gets rid of clutter and for most it's easier to bolt something on then to have to "fab" a solution.

Cjernagin,U shouldn't give out illegal advise like take it off then put back on when it needs inspection...Its the law!!! LOL

hahahaha, i know a couple turbo miata guys that have gotten pulled over and ref'ed for the illegal mods so they take them off for inspection, then put them back on after they pass hahaha

im running w/ plug on my EGR tube but it did give me a check engine light (insuffecient flow) ((01 NB)) even though i do want to run w/ my egr connected certain things kinda killed that *manifold*

It shouldn't be too complicated to make a block off plate. What should I make it out of? I am not sure aluminum will cope with the heat from the turbo. I think I have some coated steel from homedepot in the garage I could make something with.

cjernigan 01-26-2008 11:31 PM

Anything that will bolt down with some rtv and won't leak. Thick enough that it doesn't flex much. Aluminum on the intake would be just fine.

posidon42 01-27-2008 12:50 AM

hrm... might have to do this when I take the intake off to clean it and do a little bit of porting. My summer projects are starting to pile up :)

To resurrect a thread, my current setup has the valve blocked off, but the tube remains in place.
Attachment 214526

I need something to block off where the tube meets the intake manifold so that I can delete it completely. I was thinking of cutting the tube close to that flange and using some aluminum as mentioned earlier to put in between it and the manifold. Think that'll be ok? Or is there another method that would work better?
