I think the highest stage BNR hybrid will be enough to do it with a good port job.Just remember that you'll need to change from your S4 BOV to a good aftermarket one and get a S5 manifold.That and maybe add 2 more injectors to the mix and you might get at it.Need a good street port tho.

its possible, 350 would be a lot easier
