With an average pump, i.e. an Eheim, I'd go with a single nozzle entrance, possibly around 1/4 inch (6.4 mm).
With a good pump, you can go with 1/8 inch, but make sure that the jet doesnt end up breaking apart on top of the pin, or the result will be disastrous (i.e. the performance won't be as good as it can be). Your center "needle" shape is going to be critical. If you need to, feel free to extend it right into the nozzle, even if it means soldering an extra piece on it.
