I suggest buying a new turbine housing.
Turbo Housings
It's not listed, but I think that'll fit your GT2854r... they probably also have a v-band model for external gate. Call ATP and they'll set you straight. It's not cheap, but in the end, it'll be done correct.

are you sure about that?????? Must be one of those GT28XXs with the T3 turbine housing, T3 CHRA, and T3 compressor housing......
What do the numbers on that red serial plate read?
does your turbine inlet measure 1.8" x 2.3" or 1.5" x 1.9"???

It can output around 27 lb/min.
It will be a turbo with a compressor wheel just slightly smaller than the 2560, but a turbine wheel just slightly larger than the 2860.
It will more or less perform like a 2554, not as fast spooling, but with more power potential. IIRC Arkmage has a t3 with that trim, see his dyno plots: https://www.miataturbo.net/forum/t18609/
