your doing it wrong- or they are.
seriously it works
some of the best setups I have used and turbos I have sold have been tiny housings with huge inset wheels - it's the machining of the housings as well as proper wheel selection that makes the biggest difference.
Your buddies should send me their turbos...takes a while for turn around though
PS. the Z housings are VERY small for a production turbo and the GT2560 is hardly an upgrade at all if you look at the trim - size comparison - and more importantly the compressor maps of either.
