Sup guys. Will installing a set of Unorthodox Racing Lightened Pulleys be a benefit to my 03 WRX? What I meant by "benefit" is that if it will produce extra hp's from freeing some weight & @ the mean time will not damage my motor...

My car has a GT-Spec V2 Headers w/Up-pipe, Invidia Bellmouth Downpipe, HKS Carbon-Ti Catback System, Turbo XS Shorty Intake, & Turbo XS Type RFL Bov.

There is a hugh debate on whether or not it will damage your engine. But all the major tuners say it won't hurt it. Trust me there is more damage you can do to your engine than by installing a pulley. I installed one and the car ran fine. You will notice the engine is quicker/freer to rev. Definate increase/free-up of HP .....
