Just a heads up for anyone looking to purchase this. DO NOT BUY THE BELT. It will not fit as it’s for the B15 Sentra SE-R. Stillen’s technical advisors have even stated to me that it is the wrong belt. Oh and you can use the UR Crank pulley from the B15 SE-R (Stillens was just cheaper on sale when I bought mine). But either use the belt you have now or get a new one at the dealership as it works perfectly fine (so I have been advised).

I didnt install it for power gains. lol. I have had the UR pulley on all my other vehicles, its a nice addition to free up some power. But your right if your looking for power gains its not worth the money and should be purchased last.
