    Garrett Inlet types

    Hey guys,

    The only difference is one has anti surge ports and the other has a tapered bellmouth.
    The anti surge is there to reduce surge at the lower rpm range AFAIK. A few people have mentioned the high flow with these turbos at low 'ish rpm, the anti surge ports should help to reduce it.
