Yes. I'd appreciate some input on building the intake too. I just got my
manifold. It looks good and its a great start, but the flange is too small
and two of the bolt holes miss it. ('93 13B REW). How do I get around that?
Weld a plate on the edge? Paul mentions "bell mouths", but the ends of the
runners are square and flat. Should we fabricate these bells or buy them -
any sources? Also, for those who've removed metal with a die grinder - any
tricks on measuring when to stop?

Cozy IV 13B Turbo

Since you are doing a turbo don't forget the intercooler. Very important
to prevent detonation. Install an intake manifold temp sensor after
the intercooler and don't let the temp get much above about 140 degrees
F.  

Here is the design I intend to use on the KIS. It uses a custom
intercooler core from Spearco. One of these days I will get around
to doing a 3D rendering on this design.
 
If you don't want to do this you
could use an off the shelf intercooler, mount it elsewhere  and make 
the plenum a simple square tube about three by three inches or larger. Connect
it by at least 2.5 inch or 2.75 inch hose or pipe to the intercooler.
You can weld the flat parts of the runners together to form one
wall of the plenum.

The plenum will need to be fabricated out of at least .065 wall
6061 T6 aluminum to withstand the turbo pressure. You might luck out
and find some 3 inch square rectangular extrusion. It is amazing what
ten psi can do to a sheet metal box.
