hey guys, I'm working on my 87 installing a set of hooker 2151s, I ran into something I didn't expect, I didn't know the egr went into the exhaust manifold... I guess I was being ignorant, well can anyone assist me in what to do? I have this pipe, here that has Two torque bolts, but how do I cover this hole and what else must I do?
THIS PIPE
What do you want to do? If you want EGR you will have to add a port into your header. If you do not want EGR then block off the port and have a chip programmed that eliminated the EGR.
You will have to either make a blockoff plate or buy one that fits onto the intake manifold's port, if you want it gone entirely. I'd do the diode trick and save the chip removal of Code 32 for later.
If you want the EGR to work, into the header, you'll have to have one port welded in there.
From experience what do you recommend? Should I have the egr welded into my headers, as they have no port, or should I cover the port on the intake manifold. The one thing that has me worried about covering the port is temperature, I wouldn't want to reduce my engines life by covering this port. Thanks guys. Also would I need a tune "chip" if I were to cover the egr valve for sure? Thanks!
The elimination of the EGR will not reduce engine life. As noted above you could have a chip programmed to eliminate EGR or it appears you can use a resister to trick the computer into thinking the EGR is working. I have no experience with the last one so hopefully vader can update you on what is required.
My experience, I'd cut the EGR wire, yank the tube, and put the blockoff plate on there.
EGR only functions under certain part-throttle, engine hot, cruising conditions which normally occur on highway-only driving. Puttering around town, usually not at all.
I did just that on my 86, and didn't use the diode trick. I almost never got a 32 to pop up. I do not like introducing sooty air back into my engine and did not reinstall it when I changed to the new engine in the 86, or now in the 88. However, I now have it all removed in the chip. EGR removal won't hurt the engine.

what do you recommend doing for the temp switch that is plugged into that pipe, can I cut the wire? Should I unplug it, even tho it's tucked far behind the distributor?

It reads like all you need is a connection to a header tube. That's gonna take drilling and welding and a metal tube to connect with for the heat. Not a major re-engineering but you will need to slow down and sort this out to get the right parts for this.
Start looking with Summit and EGR tubes, fittings, parts. Dorman, Standard Motor Products, AC Delco, GM performance all sell EGR parts but you have to sort out what will work for you. Just the nature of modifying nowadays a part change creates other headaches in other parts.
On the other hand car will run w/o EGR but most likely need a tune. EGR is a major factor in passing smog but if not an issue for you to deal with then whatever you want goes.
help! With EGR?
