Here's two views of a solid model of the exhaust manifold that I'm
considering.  Of course it is designed to be used with a T04 turbo.  It's
hogged out of billet 321 and is currently modeled as .090 throughout.  Weight
is 3.6 lb.!  Gotta love that.  I also realized after I printed it that I
could take some more off the mounting locations.  Milling is all 2-D but
would be a bear without a bed mill with flood coolant.  Notice that turbo
port and exhaust ports intersect opening up flow path without need for
casting or fabrication.  I submit that this is the lightest, smallest,
cheapest exhaust manifold that has a chance of surviving.  If anybody wants
one it will be cheap to make extras.  I'm guessing (I repeat guessing) that
in single digit quantities these things could be had for $300-$500.

Great idea Jeff. I can mock it up when I get around to laying out my
motor intallation and mount. What is the dimension from block
to turbo flange?

You might be able to save some hogging, if not a lot of weight, 
if you went to the four bolt flange. 

Also there are some high precision casting techniques in SS.
You think anything like that would work?

Must be nice to have Solid Works.

Either way sign me up for one of them. I am going to use
a turbo too.
