Paul, 
What i want is information
on a turbocharged 13b.  The project is a mustang II,
retractable gear.  wanting about 200 hp with the turbo
normalizing at altitude.   I have a 91 turbo engine
and would like to start out with the mazda turbo.  The
more i read the more confused i get. Some  using a
wastegate, some not.  If a wastegate is used is a
muffler necessary.  Is tracy's cut down intake being
used for turbo system if not what works.  Could you
point me in the right direction for some answers.
Thanks for any help. Jim Coffman

Well Jim the 1991 turbo has a built in waste gate so I would start
with that. That is what I am going to do and Mecanair in Switzerland
is also using the stock Mazda waste gate at last report.
the 1991 turbo motor is about the best stock turbo engine for aircraft
use. Here is a picture of my setup. I have yet to build the intake manifold
but here is a sketch of what I intend to do.
200 HP flat rated is no problem if the cooling and intercooler is done right.

I think your biggest problem is getting all that in a stock Mustang II
cowl. Got any drawings on the firewall that you can upload here?
