This is our latest thinking on the intake manifold.
It has up sides and down sides. One down side is it
requires four tubing bends at about $10 to $12 bucks each.
The tubing bends are cut with a 1/2 inch straight section
so they can be bonded or welded to the casting.

The up side is it can be ported with a die grinder to match
the 1993 and later turbo engine's larger ports. The wall thickness 
will be about 3/8 of an inch to accommodate this.

It is somewhat cheaper to make the casting and a lot simpler
to make the pattern. We think but are not entirely sure about this
yet.

The dimensions on this drawing are not the gospel truth.
We are working on new drawings.

What do you all think?

BTW the fact that the 1993 and later engines make more power with larger ports
destroys the myth that velocity in intake runners is some how
an advantage :-)>
