Default Unorthodox Racing Ultra SS Puley Set for 2003 Subaru Impreza 2.5RS (bugeyed)

I am interested in getting this Unorthodox Racing Ultra SS Puley Set for my 2003 Subaru Impreza 2.5RS (bugeyed). Has anyone done this before? What kind of performance gains did you receive? I heard it doesn't affect the sound system if I ahve alot of aftermarket things running through it. Is this true? I want to amke sure everything runs proeprly while im runing these? ANd also any other input would be great! Thank you!

If you are worried about underdriven pullies, such as the Unorthodox set, having an undesired effect on your electrical system/stereo system, look into a set of lightened pullies instead. A lightened pulley will produce similar gains to an underdriven one, and won't have any negative side-effects.

Because the crank pulley by far the heaviest pulley out of the set, the maximum bang for the buck would be to replace JUST the crank pulley. Only minimal gains can be had by replacing the alternator/power steering.

So, with that in mind, I'd recommend the MrJosh lightweight crank pulley (about $90, look in the vendor forums at www.rs25.com), or the Perrin crank pulley ($120, but looks really nice!). I have the MrJosh and couldn't be happier with it.

How are the performance gains with the Mr Josh? I would imagine that you would get more gains if you bought a set, not just one individual pulley.
