I would hold off on a impeller till you had motor mods. Then go with a 2005+ pump upgrade and 14/20 dy.

A stock 03 with no engine mods, a Riva 13/20 setback will work fine but you need to put on an 87mm pump nozzle. If you plan on doing engine or pump changes, I would hold off on the impeller because it will need a different impeller and there not cheap.
