exhaust mani replacement

[FEARTH38EARD]

In the middle of replacing my exhaust manifold with a '95 tube header style manifold.. there is a metal corrigated type tube that goes in close to the last manifold bolt (next to fire wall) it appears to also attached to the intake manifold but I can't be sure. Anyone know what this is? I know others have done this swap, and wondering what they did with this metal tube..

Thats the EGR tube.

 

[FEARTH38EARD]

Can I just plug it off? There isn't a spot for it on the newer mani..

You can plug it off, but if you do it needs to be plugged on both sides, and it will trip a check engine light.

 

[FEARTH38EARD]

My truck doesn't have a check engine light to my knowledge. Its an '83. As long as it won't make it run bad I'm not worried. So its just feeding exhaust gasses back in to the intake? Probably be harder to pass a sniff style emissions test then huh?

Deleting the egr might make you fail a sniffer test it might not. You say you are putting 95 headers in an 83. What engine is in it?

2.3... from what I have seen on here you can use the tube header style manifolds off of the 93-95 four bangers on the first gen four bangers. It looks like it will fit just fine, and free up some space. Just no port for that egr tube.

He ranger header has no performance value.

 

[FEARTH38EARD]

Yeah, I'm not looking to increase performance... my original has a large crack, and a junk yard replacement off of a 93-95 was easy to find. It looks like it will give me more room on that side of the engine which is plus also. Guess I will just pull the tube at the intake and put a bolt in it. Should work right? Any other adverse effects to consider before plugging it off?

Is your truck carbureted? If so, you can probably do without the EGR...

The tube header that I found from a Mazda (93 or 94) had an EGR bung right beside the down pipe (below the collector) and I was able to connect my EGR to that...The FI models from earlier years had the EGR connected to that point...it even had the same nut size as the 2.0 so It wasn't too hard to connect it...although I did, by law, have to have it.

I made up an EGR pipe out of copper pipe and it fit OK...but I will make another one up some day out of conduit or something else...copper is just too expensive to be sucking gas fumes and gunk into my combustion chambers...

 

[FEARTH38EARD]

Yeah Mark it has the original carter 1 barrel carb. I was going to do the weber mod but just ended up rebuilding the original. Runs better than ever, and even idles surprisingly.

 

[adsm08]

Yeah, a carb system will not be as adversely effected by deleting the EGR system.

I could have come up with that faster, but I was on my phone.

Thanks for all the replys everyone.
