Seems the 1uz has some options like the Eaton M90 or M112 or MP112. Not sure if the the 1uz manifold plate people are using fits a 2uz or not. that's actually why I'm here to find out myself.
However www.urdusa.com has a stage 3 centrifugal supercharger and intercooler kit for the vvti 4.7L 4Runner and GX470. I've asked the owner Gadget if the kit fits a Tundra and he said no, but it can be modified to fit. Hope that helps some.
