Valve guide material for boosted apps

I've been using bronze guides on all NA motors, but am interested in thoughts on what I should use for boosted applications. The application is a turbo diesel, 70PSI boost, water injected after turbo in the manifold. Not sure what the EGT's or charge temp is.

What is the best choice---bronze or cast or cast with bronze liner? Thanks for the help.

A guide like Brad Anderson uses in his hemi engines or Alan Johnson uses is I believe a steel guide with a bronze liner, they hold up very good in a boosted application. Hope this helps, good luck!
