The VF34 i think is rated to about 350bhp, it is a roller-bearing turbo and was used on the JDM STi's, STi type UK use a VF35 which are almost identical apart the bearings used.

Some Type UK's DID come fitted with the VF34....these were used on only a few Bug-Eye STI Type UK's...thes std turbo on those cars was the VF30.

I'm looking at upgrade turbos at the moment. VF34 maxes out at around 350, unless this one is a hybrid.

im sure the vf34 has a p18 housing, rather than the smaller housing on the vf35
