I have been checking out supercharger and wrx swaps, but that is not for me. I don't plan on racing this thing, I just want a little extra umph for the mountains here. I gotta say, I am very dissapointed with the performance out of the '04 subaru. We had a '99 2.5L manual and that thing never lacked power. I realize an auto is going to be a little less powerfull but come on subaru, what were you thinking? As far as the kit I posted, It won't be hard for me to install it, I just wanted to know if it was going to last, or worth doing it?
