Also that turbos external wastegate so would need manifold mods.

And has a .82 exhaust housing, which makes it far bigger than even an RS500 T4

TBH that E.Bay ad makes me think the bloke hanst got a fucking clue what hes on about.

Such a big ex housing, but claiming 300bhp from it makes me think small compressor, which makes me think its just a turbo off a diesel truck of summat and totaly the wrong spec for a petrol application (dervs make much more exhaust gas so use bigger ex housings)
