    I am considering switching from my single to twins, I want to run turbos similar to hp's 57mm twins. Anyone know the sizes and a/r's of the 57's and the 50's??

    They are T3/TO4E turbos, the "57mm" turbos use 57-trim TO4E compressor wheels (56mm inducer) with a Stage III turbine wheel and a .63 A/R turbine housing. Equivalent PTE turbo is a SC3427E. The "50mm" turbos use 50-trim TO4E compressor wheels (54mm inducer) with a Stage IIII turbine wheel and a .63 A/R turbine housing. Equivalent PTE turbo is a SC5027E. I really don't know why they call them 57mm and 50mm turbos, it's the totally incorrect nomenclature, and I would expect a turbo company to have a pretty good grasp of turbo knowledge.....
