The turbo is just hanging free in the pictures.  Sven will build a turbo
mount.  I decided to leave that to him since he knows better than I how
strong it needs to be.  For the sake of convenience, it seems that the
turbo mount might somehow tie in with the engine mount.  There are not a
lot attachment points on that side of the engine.

The reason for my asking is that I see the turbo mounting as a critical
factor in a system like this.  Usually the outside loads placed on the
pipes by weight/vibration are responsible for cracking more so than the
heat/exhaust alone.

Jeff Spitzer

As usual, I agree with you.  Most cracks in exhaust systems could be
avoided when it is originally built.  Another thing that is often
overlooked is purging the inside of the pipe, or at least using a backup
flux during welding.  There is a flexible bellows in the turbo inlet
pipe to isolate it from the turbo.  The turbo will be rigidly mounted to
the engine itself so all of the load will be carried by the mount, and
not the orange glowing pipes.  It looked really cool at full power on
the dyno.  My version of modern art.
