I was considering a draw through setup a while ago and wanted to run a side draft of some sort.
I came across a place on fleabay that was selling 52mm side draft Webbers, IIRC someone had an adapter to put a DCOE on the front of a turbo, not that it would be hard to fab.
Food for thought, as the lower the restriction before the turbo, the less heat it builds for a given boost (within it's design limits).
