Demo man,
Would be happy to price you up for fabrication of an inlet manifold with internal trumpets if you get stuck.
Glad you have found the TTV flywheel. I was the one who first approched them with the design as i needed something for a friends car i was working on. With a little help from Alan the design was finallised and he worked his CNC magic. There are photos of the first prototype in my kit car project thread and i also supplied Dan from FastFord with one for his zetec turbo project.
They really are a bargain at £188.
