instead of starting a new thread i will put it here.. how would the following compare on a built ej257?

current turbo: Blouch TD05/06 20G which is a TD05 with TDO6 compressor wheel and compressor housing.

to

Blouch RBK Dominator 2.5XTR Polka Pickle

and also to

Blouch RBK Dominator 3.0XTR Polka Pickle

what is the difference between 8cm and 10cm housing? What would be better?
