FYI -if you are AutoX-ing under SCCA classing, this would put you into either a Prepared or Modified category, much like adding forced induction or CF body panels. the perfromance gain is not worth the class jump, as you'll be up against vehicles with drastically greater levels of preparedeness (IE: swapped motors, turbos, etc). The same is true for the NST and other underdrive pulleys. If you are an honest autocrosser who wants to race/win on skill and not cheating, then you have to disclose these mods, or ask the other in your desired class to grant you an exception to run with them. Generally, they will do so if its not performance-enhancing (non-standard rims, add-on spoiler, etc.), but will probably ask you to register in your proper class if you've done any of the mods listed above.
There are many clubs out there that use a much less-stringent classing system, and they are perfect for cars that have been modded for street performance (BMWSCCA, PCA, NASA), and you can register in exhibition classes to compete without winnign trophies or points.
If you really want to compete seriously and earn points, plan your mods around the class in which you think you'll be competitive (H-stock or ST are probably the only 2 classes the Yaris has much chance in untill you go full-bore and swap-in a 2.4L or a massive turbo kit and go full Modified class.)

There is a Street Touring (ST) class that is intended to allow many of the most common handling mods found on "tuner" cars, but it still will not allow a change to the engine management system (throttle controller). Not sure about the pulley swap. SCCA.com has a full classign checklist on its site if you want to see where you'd end-up.
Remember: either be honest and ask for a "waiver" fromt he competition, ragister in your correct class, or don't show up. Its all about being the best driver!
