turbine trim question

i was on a website and it says a t3 super 60 trim for the turbo and then it has a different tab where you can select the turbine housing. i was wondering if these kits come with the turbine itself. http://turbocalculator.com/sale-turbokits.php thats the website if it will help to visit it to see wat im talking about.

i'm pretty sure the turbo trim is the turbine. i looked at that place back in october but i didnt really know much about what size everthing should be so i'm not bothering with it.
