The number "070" or "060" will be on the turbine housing depending on whether or not it is a 6cm or 7cm housing. Here is a pic showing where to look for the number.

Well if its been ported more than likely its a 7cm opening. If you post a pic we can tell you right away its a no brainer to see the diffrence.
