You could count the turbine blades, but requires to remove the down pipe, use a mirror and count the blades. IIRC, the 03 turbo had 10 blades, the late '04 had 13, and 05-07 had 15.
Or you could just look at the turbo to pedestal mounts. The '03 turbo has the rear mounting bolt going horizontal thru the pedestal and into the turbo. The '04-07 turbos had the rear bolt going vertical thru the turbo and into the pedestal.
Pic below, blue circle is the '03, red circle is the 04-07.
