EGR Removal?

jstang94gt · Apr 11, 2006

Alright, while working on my car ('94 GT) this weekend, one of my friends recommended I remove the EGR and smog pump from the car to clean up the engine bay and get rid of some unnecessary weight. I was reading around and found out that there's no concensus on whether removing the EGR will help the car at all, and that it actually hurts performance in many cases, especially without a tweecer or similar tuner.

I'm just wondering if anyone has done this and had any problems, or if I should just leave it be. The engine is bone stock, only have exhaust and gears done. I'm still learning, and reading arguments back and forth makes me wanna , so any help or personal experience would be awesome. Thanks in advance.

DON'T DO IT!!! I capped off my EGR because my BBK LT headers didn't have the EGR bung...big mistake as my car had a severe detonation problem afterwards that only stopped after I did the Fox TB converstion and ran the Fox EGR setup. There are no benefits to deleting EGR other than "cleaning up the engine bay" and you will fail an inspection if you have one in your area. If you want I can send you the scientific reasons not to delete EGR, but I think staving off the ping thing is probably good enough. You can delete it if you shut the function off inside of the computer at the same time with a tuner, but you'd still fail an inspection.

also did the fox tb swap and used the foxes internal egr. cleans it up nicely. there is no reason to delete it unless like 18mustangs said, you remove it from the stock program. it is only turned on at part throttle to reduce combustion temps while more timing is added to help combat emmissions. if you just remove it, the computer will still add too much timing and you will detonate most likely. at WOT it is turned off so it wont affect anything. leave it be, or get a chip. or do the cool thing and do a fox tb swap and that will eliminate that p.i.t.a. external egr tube. i hate that thing

At WOT and idle, the EGR is inop, thus negates the performance reasons for removing it.

The smog pump runs at idle for the first 120 seconds or so, and also at part throttle, but is inop at WOT.

So, the only reason is for removing junk from the bay, and you need to rig the egr sensor so the comp thinks the egr is still there.
