I actually did not take any side by side pictures, but I'll probably have the turbo off in the next week or two to clock it for my IC, so I'll take some then. The turbine housing isn't much bigger than the 55 trim, but the turbine wheel is. I like it alot, even with stock fueling. The wastegate is set at 18 from the factory, so it should easily be able to do 22-24 psi.
Herlevi told me they could squeeze out 115cc from the 6mm with delivery valve work, but at that point I would probably just get bigger elements. The pump is good to 6000rpm!
I may also start a new thread, don't want to veer off topic too much ��
