If you are running an e23 745i exhaust manifold this might interest you.
I have been working on this for a few months now and I am about ready to move forward. I have the quote back from the machine shop for the work. It will be $225 plus $150 for initial startup to make 5 adapter plates. After that It will be another $75-$100 to press and assemble the plate onto the bottom of a tial 38mm wastegate. After adding in the price of the wastegate we are looking at about $600 (give or take a couple of $$$) for a complete unit to make a run at this.
I need 5 people to commit to get this started... I'm already in so we really only need 4. If you're interested let me know. I will probably only do this once so don't miss out.
This adapter plate will be made from T304 Stainless, which means no rust and better heat properties than the other piece I have.

Any chance you want to make another run? How much did you guys charge for a complete piece? PM me if you like.
Sweeney made it. I thought he only made one for my personal 745i. I have spoken to the current Owner of that car and it's still in one piece. So you either have the one from that car or Sweeney made two and I sold one. I don't recall exactly. I don't see any talk of machining the valve. Do you have a plan for that?

Just saw this post. I think TCD made a few of them back in the day. I'm trying to make another run at it with a different material that won't rust.
Just ribbing ya, man... Those adapters are my little creation. I used continuously cast ductile iron so the thermal expansion characteristics matched the elbow.

Ah ok, I heard you made them. Well Maybe he will chime in. Maybe I already have a reproduction version haha.
Why do I need to machine the valve? The stock WG and Tial piece have the same size. I was going to make the plate and press it on.
I know I made a couple of them and there was no machining of the Tial valve. The valve guide was removed from the Tial's base and pressed into the adapter. Pretty simple actually.

That's what I was thinking. I'm looking at around $300 before buying the WG. Is that a good price? Why did you only make a couple? Did you do these by hand!?
The price for me to do by hand is closer to $600 before the WG purchase.

If it was so simple you should have made ten.
I lost interest after the challenge of figuring it out... not making them. Plus, electron guns are more profitable

I used my lathe and Bridgeport manual mill. For production I'd most likely have the square form cut from plate stock along with the holes using water jet and then finish up on a lathe.
The problem you'll run into is the 'economy of scale' vs. demand. This is why we didn't bother pursuing these.

Do you work in E-beam vapor deposition or EDM?
Next to wastegate adapter plates, turbo V8 BMWs, bronze statuary for National Parks and playing with firearms I also make high voltage feedthroughs (electron guns) for Scanning Electron Micro Probes... but I don't know what the heated metal box in my kitchen is used for.
I used to work in research doing e-beam vapor deposition of ceramic and metallic coatings (sometime using plasma activation.) It was always easier to tell people it worked on magic.

Doesn't look like we will get very far. Everyone wants a cheaper solution.
Also, I'm not sure if you ever ran this thing, but the WG diaphragm has a hole in it. No way it would have sealed and worked. I ordered a new one but thought you might want to know in case you were having trouble with it.
