turbo exhaust housing port question

[steve-o_95_GST]

i have an blown t-25 lying around my garage and i was wondering how much material would i have to remove so the turbo can keep boost at higher rpm? right now the one on my car has one of the bolt holes srtipped out by the person i bought it from removing the stud so i wanted to swap housings.

porting the t-25 isn't going to help much...it runs out of steam up top anyway....just do a mild port to clean up the exhaust side and maybe port the o2 housing to help with boost creep.
