I believe that I have a picture of this engine:

I found it interesting that the throttle body is _before_ the
turbo inlet.  I would think that causing a vacuum in the whole
intake tract would cause poorer throttle response (anathema
of a road racing engine), but that's only a guess.  Anyone
got a good explanation for this?  Lower stress on turbine shaft?
