I got a turbo off of a navastar a while back. Recently I pulled it apart. Now I am tring to identify the turbine wheel and shaft. The od measures roughly 2.900. It has 11 blades so you can not get a accurate measurement because of the odd number. It measures roughly 2.530 at the small end. The shaft has 933-06 on it. Does anybody have a idea size and trim it is?
