I am still looking at various options for a low profile intake and have some questions.  Tom
Phillips, a welder specializing in exhaust systems, went with me to an engine junk yard and we
looked at various configurations.  He suggested that it might be easier to start with a stock
manifold than to build from scratch.  There is a toyota v6 truck manifold that might work. It is
15" wide and only 3" thick.  It is interesting in that the throttle body air enters at the center
of the plenum, rather than at one end, and is such that the air passes across to the plenum and
then returns thru the runners to the same side of the engine.  With the turbo I hoped to use this
would put the throttle body on the same side of the engine as the turbo.

    I assume that production vehicles use cast intakes because a lot of details can be made from
just one piece and that the casting process dictates that the piece has a certain wall thickness?
How much weight savings would I get from welding my own from tubing?  This toyota manifold would
only have about 12" of runner behind my primary injectors and the inlake ports.  Is this too
little?  Other builders seem to have more.  The plenum would actually be inboard of the oil
dipstick, rather than outboard.  Looking around the junk yard, I saw no engines that had injectors
in the manifold with any distance to them.
    Tracy, is that diagram depicting your engine and cowl on your website accurate or to scale?
