I didn't make it but I can get some made for anyone who wants one.
I am trying to get the guy who made it to list on his ebay site so I can be left out of the transaction.

I don't like it. I can't see the 2 bolt side sealing very well under the pressure caused by the turbo.

Are you going to stud that flange?

If I also get it tack welded would that give you a warm fuzzy..

Do not like.

I would still weld it, at least after you have it bolted in place.... Having just a catback hanging off that flange has given justin and I tons of problems.. I would only imagine what a turbo and the turbo exhaust would do to it.

I will get it tack welded just for good measure but I love how it fits. Trying to weld a rectangle to a circle is much harder than it looks. However, a caveman could weld this on and it still look like a factory job with OPTIMAL airflow. Some are ok with blocked airflow, hacked up manifold, and ugly looking welds. Me, I want performance, quality, and beauty and this adapter fits the bill. Whats not to like? Fits like a glove and no welding needed unless you want to.

The turbo will need a good brace for sure.

On my turbo 3.4L, I fabricated a special spring mounted (free floating) support stand/bracket for the turbo. The Garrett T3/T4 turbo is firmly supported so it can't stress the pipes, but there is room for expansion movement. That insures no breakage. I would not hang a turbo on an exhaust manifold or pipe. If piping is needed to route, I would also recommend using only stainless steel . Mild steel will work but won't last as long.
I like the turbo mounting adapter flange design shown in this post. Ingenious idea.

The flange does look really nice. I just don't like the idea of using those two bolts that are so far apart. Put a bead all the way around it and it'll be perfect!

Yeah, I was thinking of some kind of T bar or L bar bolted/welded to the cradle and trunk wall.
MstangsBware is also working on a rear mounted Turbo for his car and has a few ideas about some bracketry.

It has to be bolted to the engine. Cannot bolt the turbo bracket to the body or cradle. The vibration and movement of the engine will result in cracks. The best would be to have 2 brackets one going up and bracing the turbo to the head and another bracket going down and bolting somewhere above the oil pan. 1/4 inch steel bracket would be OK.

What about some half inch bars like this? welded from flange to flange.

You'll need something from the bottom too. From the turbo exhaust housing to the block.

I'm basically copying your setup with a lighter Turbo 18lbs. You don't have any support. Great idea though.

Yeah, I wouldn't worry about it but others want you to brace it up.

Sweet! Yea I would additionally weld it after it was bolted on, however, this bracket also insures that your turbo is perfectly mounted perpendicular and flat. What is the cost of this bracket?

I paid $60 plus shipping. I assume they will be a little less if offered on website since mine was a custom job.

I wish... All I have is what I posted. The guy (Joey) is very busy as he has NOT been answering emails.
I told him to use a 3800 Gasket to build the adapter to the correct dimensions and he did a great job.
I was thinking about having a run of 10 or so made but decided that he could just sell them from his ebay site instead.

With the weight that will be hanging off the end and the temps that the manifold flange will see, I too would recommend welding the flange solid to the manifold.

Hopefully he gets that corrected as i sent him some wording updates. I think he forgot the details of what he built.
