Testarossa Throttle Bodies

its a long shot but I would try Norwood Performance.. Sponsor here on the sight.. He may have one laying around.

Is this a case where the Euro TB's are, perhaps, bored to a larger inside diameter than their North American counterparts?

If so, then wouldn't a simple overbore of the N.A. version get you where you want to be?

Or is it something else entirely?

Just curious.
