I have a modded stock tpi base and I was wondering if anyone knows if you can still run the EGR set up. If not, do I just need the "delete" plate or is there more ports to block?

 

Vortec heads don't have the heat riser so if you need EGR have to use a ext source like the Vette TPI setup

The EGR delete plate would be all that's required to seal the EGR valve hole

 

.

 

To be clear, is this an aftermarket TPI base for Vortec heads, or did someone take a stock TPI base, weld material to it, and remachine it?

You can get a kit that mounts to the Vortec TPI base that brings exhaust gases from the exhaust manifold/header to the base and makes the EGR functional. Check out www.sdparts.com, p/n SD3816 (you may have to call them - searching their site for the p/n only came up with the TPI Vortec base).

Or, get/make a block-off plate for the valve mount boss.

 

Thank you, plate was ordered (for now till smog time)

 

This is a stock tune port base, machined to work with the vortecs, material was added to it

 

Im looking for a corvette set up (pictures) and I cant find anything. My headers have the port to run the egr set up from sdparts.com but where would the other end run? (since this isnt the "vortec casted tpi base"
