For Savington... 962 pics
Per Andrews request here are some pics of a Porsche 962 we have at work... just came in so we're going over a few things. Here's the turbo section specifically... it's a KKK K36, dual wastegates, no blowoff/bypass valves.
Sorry I can't answer any questions of a car history/ownership nature for privacy reasons of our customer (hence the pics not being identifiable to a particular car). Any other questions I can answer...
Enjoy...

Bill, does this owner have any problems with their nuts/studs on their car?
As you have seen on both mine and Andrew's car in person, our turbo miatas seem to have some serious issues on track keeping the turbos on.
When you get some free time, swing on into this thread, i would love to hear what you think:

Doesn't look like anything special bolting the dp and turbine housing together... or maybe there's a science to those different thickness nuts? 
I am amazed to see all the bellowed/accordian pipe used in the wastegate tubing as I thought that stuff was frail. Also of note is how far downstream the WGs enter the manifold stream. I've seen this on other prototype turbo cars. Not much of concern there about how close the WG is to the turbine. Of course this is all old school and w/o the owner's comments, there's no telling if he has the same problems.

The first thing I notice is the bellowed/accordian pipe that m2cucar mentioned.
The second is the fact that the exhaust manifold is not supporting the weight of the turbo. There are brackets for that.
The third thing is the presence of a heat shield for the wastegate actuator.
Fourth, it isn't a water cooled turbo (haha).
Fifth, twin scroll turbine housing.
Sixth, EGT bungs in both the uppipe and downpipe.
It looks like the stainless flange for the uppipe to turbine inlet would expand at a similar rate to the same grade of stainless studs if that is what they are using.
Sexy hardware, indeed.

We all thought the different size hardware was pretty special too... we made a special point to leave them to show the owner what a bangup job his former prep shop was doing. They're not staying around.
As far as it not being a water cooled turbo... there's no water on board to cool it with being it's an air cooled engine. The accordian sections may look frail, but they (and the rest of the exhaust piping) are all Inconel... fairly sturdy stuff. They used a similar setup on 935s without things falling off or breaking as well.

^As if it hasn't been said before. 
I'm all for supporting brackets - I'm running an SSA mild stainless thin wall manifold.
The accordian sections look just like the OE stuff the germans use - same material? You see it still stuck to a lot of the OE WGs that come up used on eBay.

M2 - no idea if it's the same material as OEM street car stuff or not, the only P-car street turbo I have any experience with are 993TT's and they don't use any at all.
Sav - You're welcome... and as M2 surmised, there's just no room anywhere else to put the turbo. I haven't worked on one of the twin-turbo 962's, would be interesting to see where they stuck those.
