Depends on the engine, no? For instance with the OM 60X family of engines the NA head has prechambers that have a neck OD of 14 mm, the Turbo engines in that family have prechambers with a neck OD of 15 mm. So between the NA and Turbo models the cylinder heads have different diameter holes for the prechambers.
Seems like that might indicate the OM 61X family might use the same idea also but I don't know that for certain about those engines.
