You would have to buy a prefabbed kit with manifolds and piping or have something custom made. To convert to a single turbo setup you wil have to redo the manifolds to work for a single turbo setup since the factory setup it twin turbo with a turbo on each manifold. Either finding a kit premade or having one custom made..its going to take some $$$ unless you can fab up your own piping and manifold design.
