Be prepared to bombarded with different views as this is a personal choice and pick carefully , vf36 is a Twin scroll so you won’t be fitting that unless you want the task of a full Conversion.
Personally these are your options
VF43/48 designed for the 2.5 Sti theses come up cheap
Vf34/35 more the 2.ltr but should spool great on a 2.5
Td04 hybrid good for 320hp
Td05 18g
Sc36
