Emissions delete - 83300d - 05-16-2012
Been reading up on EGR and wonder how many people have deleted the emission components on their cars? Have done it lots on other cars, but wonder how it affects the 300d.
RE: Emissions delete - winmutt - 05-16-2012
It affects it the same as any other car. Less dirt in the intake == longer life == less pollution from making a new car.

Let ya know in a week :-)
Recirculated exhaust just plain sound bad to me.
RE: Emissions delete - sassparilla_kid - 05-17-2012
But, don't you know, its there to "lower combustion temperatures to reduce the NOX"!!!!!!!!!!!!! lol, possibly the dumbest idea I have ever heard, lets just put exhaust back into the engine!!! My egr is going away this weekend, so I'll post back in a couple days with the results
RE: Emissions delete - 83300d - 05-19-2012
So what is the easiest way to delete it on the 300d? Change out the intake?
RE: Emissions delete - sassparilla_kid - 05-19-2012
That, or make/buy block off plates, which is probably the simplest, easiest method.
RE: Emissions delete - 83300d - 05-20-2012
Who makes some block off plates for this?
RE: Emissions delete - lgreeley83 - 05-20-2012
i looked a while ago (2 months) there was a guy on ebay selling them but none for sale now. Emailed him with no response. Could just get a small chunk of metal machined.
Block off plate

i found a set in the yards a long time ago, but if I had to make my own, I would get the gasket (intake side) and a piece of plate and go to town. The exhaust part was just a thin piece of sheet cut to the right size and slightly domed...a ball peen and a socket would likely work. It is installed with the stock band clamp deal. You could also likely get an extra exhaust fitting and have a piece welded to it as an alternative...depends on how good your local yards are. I hear a quarter fits well in the exhaust side as well... some people have just JB welded a quarter inside it effectively blocking the EGR but leaving the whole piece intact...I like the space provided by deleting it tho...

Try a carriage bolt of the proper size (hardware store). 150 mi. from home when the egr pipe burned through. Was pulling grade at the time,kept looking back and all around for that Semi-truck that was quickly bearing down,no kidding ,everyone was looking!!
Where is THAT truck LOL..

I finished installing my non-egr manifolds last night, and am quite pleased. I would say the car definitely has increased performance, and while it is noticeable throughout the whole rpm range, it is most noticeable in the lower rpm's
RE: Emissions delete - 83300d - 05-22-2012
What year of car had the non egr manifolds? Hard to find?
RE: Emissions delete - w123love - 05-22-2012
’78-80 SD’s. Slightly easier to find than the 115 mani that we all desire. I’ve got an really nice non-egr exhaust that I am going to put up for sale soon. Its ceramic coated and tapped for a pyro meter and exhaust manifold pressure.
RE: Emissions delete - sassparilla_kid - 05-22-2012
My non-egr manifolds came from an '80 300SD
RE: Emissions delete - 83300d - 05-28-2012
Sassparilla_kid - just bought a 1980 SD intake manifold and wondered if you port matched yours? or any other interesting mods before you bolted it on?
Got a link to your car build?
RE: Emissions delete - w123love - 05-28-2012
Just bolted my SD manifolds on this past saturday. Took me the better part of the day but was pretty cut and paste.
Before I put them in I had both ceramic coated. The intake in a very nice shiny silver and the exhaust in black. They came out great. I smoothed the intake down so it looks nice and not all ripply. I really suggest the ceramic coating for keeping the heat in.

Hey I didn't get them port matched or do anything really fancy, all I did was clean them up and paint the exhaust manifold
Here's a link to my car build:

I should have put the w115 manifold that I have on when I did this but I didn't have a silicon elbow to hook it up to the turbo. But still, the non-egr manifold is definitely better than the egr-one
