Yes a competent machine shop can drill out the hole for the speedo cable.

The basic design is the same but the Turbo specs are larger. The strut mount is longer but thinner, the caliper mount is 18mm bigger, and the hubs/discs aren't the same. If you want the Turbo brakes you'll need all the Turbo parts, they don't interchange with the NA parts in the front, as they do in the rear.
