How Bad Is This?

Mine looked somewhat similar to that before porting. However, I just purchased a 7cm housing and took my old one off to find that the crack had actually grown all the way through the wastegate passage and into the turbine area. There was a small deposit of metal at the end of the crack that was INCREDIBLY close to the turbine blades. I guarentee that if I would have driven for another month I would be buying a new turbo! I would purchase a 7cm housing and port that, its cheap insurance... unless you want to buy a new turbo!
