I bought a turbo from a friend and had a few questions about it. The origin of the turbo is pretty much unknown except for the facts that on the hotside its .80 a/r on the cold its .60 a/r and it has a .60 trim... if anyone knows a little more about what all this means? and could relay it to me that would be great, oh and its a garrett Also have a question concerning where the oil drain flange is.. the turbo is planned to be mounted on a b18 so the flange is pointing up actually so I was wondering if it is possible to rotate the housing? (I will be removing the external wastegate anyway)
