Woodsman,
No, the belt will be a different length and you'll want to make a note of the correct size because you'll no longer be able to just order a belt for a boxster.
I never noticed that Pedro's pulley doesn't have a hole in it. Show stopper for me, since being able to lock the engine at TDC is more than just kind of handy.

I was just reading the instructions for Pedro's/TuneRSMotorsports one, and it says to torque the bolt and do the final tightening to put the car in the highest gear and set the parking brake. So I guess that could work. Some Miata folks do that too. When we did our Miata WP/Timing belt we bought the crank pulley hold tool from Flying Miata. When I did my UDP (with the RSS) I used their tool and a block of wood from a 2x4 and wedged it against the top of the front engine compartment access.

Keep the old pulley for timing reasons. Several or most of the replacements require you trim the lug that the hole for the pin goes in as well.

The biggest reason is not for the daily driver guys. It for the track guys. The high rpm required on track overheat the pump and PS fluid. A smaller pulley means lower RPM on the PS pump lower operating temp on the PS fluid. I've wacked 2 pumps in 5 years of track driving.
