Paul,
Could I ask you and the group a question.
Question:  If I am going to use a turbo 13B with EFI is there any
advantage to a dynamic chamber for the intake manifold since it will
be pressurized from the turbo.

In a normally aspirated engine the tuned intake yeilds more power.  In a
turbo engine the tuned intake is not needed because you can just close the
wastegate for more power.  The tuned intake would result in a slightly
(measureable?) reduction in fuel consumption on the turbo engine but more
important for a car guy should improve "drivability" (aka
reasonable/predictable/repeatable torque curve) if properly done.
