Swapping Turbine Housing, how hard is it?

I want to change my turbine housing from a .48 to a .63. IS it very difficult? Where can I get one. I have a t3/t4-E hybrid with a stage 3 hot side.

Due to the location of the lower two manifold-mounting bolts and some of the center-section attachment bolts, it's probably easiest to do it on the bench by removing the entire turbo and manifold as an assembly. After doing so, these bolts are much more accessible.

A word of caution: Soak the 5 exh-elbow bolts thoroughly with PB Blaster and rock 'em back and forth when you first crack 'em loose - they have a tendency to break off in the turbine housing. :dunno:
