VF43
... The VF43 utilizes a thrust bearing design and the P15 exhaust housing. The difference between the VF43 and the VF39 used previously on STI's is the size of the wastegate. The VF43 has a larger wastegate designed to reduce boost creep issues.
Sorry FAIL on the above bits of info (Repost from OzLiberty forum)

VF39 is a PZ18 exhaust housing..
also

VF43 is a PZ18 exhaust housing.....
which makes sense as Subaru would not put a smaller P15 exhaust housing on the larger 2.5lt EJ257 engine for the OZ/US MY06-07 STi.

08 STI

VF48 is from all reports, visually the same as the VF30/39/43. Same compressor wheels.

Changes at this stage seem to be to the wastegate actuator and arm compared to the VF43.
