LS1 EGR questions
Hello.
Doing a LS1 swap into a 65 Impala. Replaced the stock manifolds with headers from Street and Performance. These have the EGR bungs welded in already.
My questions...now that I am not using the stock headers, what will I do with the EGR hoses that went to the stock manifolds? I am guessing they are not needed. The hoses go back to a circular valve which also supplies vacuum for the brakes.
Is there a general rule for which side the EGR valves on the collector face? I know it may sound stupid but I have lots of room since I am frame off now and will not always be that way.
I can take photos of the part if needed.
Thanks.

No I plan on using one pair in the header collectors, I am talking about the hoses that go to the front of the headers.

You could do what i did and cut a piece of 1/4" aluminum to fit.
They do sell a kit
Is this what you're talking about? http://cgi.ebay.com/ebaymotors/LS1-C...Q5fAccessories

not the manifold, I have headers now. The stock manifold would not fit with the power steering box. I am speaking of the hoses.

top photo of hose on drivers side
Connector on that goes to top of manifold
Top of manifold where hose connects to
Other end of the hose connection
Small line from connection.
Hope this will clear it up. PLEASE remember, I now have headers and the headers have no connection for this hookup. I am trying to eliminate it since I do not want to cut holes in my shiny new headers that are coated.Last edited by leon phelps; 07-03-2010 at 11:28 AM.

as for the small cylinder behind the head, you can take it off and cap off any lines that went to it. The hoses that ran to the manifolds can be removed along with the air pump that they connect to. That whole setup has nothing to do with breaks

Dumb question then, what does the third large hose that comes from the pump connect to?

Well, I looked up the GM part number. The valve is called a "W" valve. I see it goes to either a solenoid or a sensor a short distance from the valve. The part has an gas hose in and one out. There is also an orange and pink/black wire connected to it. The small hose then exits the unknown part and goes along the trans/engine mating surface then goes into a small filter then to a "T".
Any idea what this small valve or solenoid is called? Can I eliminate it too? If I remove it, I guess I would just tape the connector to the harness and leave it out of the way. Would I just get rid of the T on the back of the engine and put an inline coupler or do something else?
Thanks in advance.

From i know about elimainating EGR/AIR system my answer will be yes you can eliminate it. the only thing is that if you dont have the codes deleted by a tune the SES light will be on all the time.
