Not that I know of, but if they did it most likely wouldnt be worth the cost. I honestly wouldnt worry about pulleys of all things. If power is really THAT big a deal to so many NA owners, then it looks like more need to be following the BEGi thread for a turbo... by follow I mean call Corky and see where he stands more often .... or just buy an SRT. Like I said CAI, TB, Tune, and wavetrac... If that isnt enough, Forced induction or buy another car.... Im quite content with my car, if a turbo gets made then, nice . If not, oh well, my car still looks better than 80% of the cars on the roads today and that makes me fell quite good .
