Default EGR Plug & WG

Has anyone removed the plug on their log style (stock) exhaust manifold and hooked up a WG to this? My thoughts are that one could unscrew this plug, screw in or friction fit/weld a 90 elbow and then weld tubing to a WG adapter. The ID would almost be the same as the stock WG opening inside the stock T3 faceplate.

I believe Jak did some work on this. Perhaps email him? Also there was some talk about it on TSN a few years ago. Maybe do some searching over there.

What's the ID of the ERG hole?

i could be way off, but i am thinking it looked like a 14mm thread.

i have pulled a couple of plugs out of cracked manifolds in the past couple of years.

Been thinking about this as i'll be turbo'ing a 16v n/a, i think it would be too small, one of the advantages of the exWG is the ability to flow more gas away than the stock Wg poppet valve, if you reduce the exit too much you'll end up getting boost creep. Ideally you would need to bore it out to between 25-40mm to get descent flow.
