Question for the turbo gurus out there

[Pushit2.0]

I have a gt 4202 standard bearing 2l build that makes good power. Last year at 44psi on e98 my car made 947awhp at DB in shoot out mode.

I will buy a billet 67 or Borg Warner version of the 4202 when this turbo lets the ghost out, so far 3 years at 40psi+ but I know my days are numbered.

Call up MAP for a good price when you make a choice on turbo brand and size.
