If I were a betting man, I'd bet the OP's turbo didn't last after that rebuild.

How about sharing why you say that. What specifically do you think he did wrong?

The OP's turbo was damaged beyond what a simple repair kit would fix and he is completely doing it the wrong way. The damage was not assessed properly which is key to repairing a turbocharger.

NEVER shove a screw driver into your turbine wheel. All of the steps he posted are great if you want to bend the shaft on your turbo and end up with a much worse situation than you started with. Let a lone not balancing the rotating assembly prior to assembly.

I use a special fixture for the GTP38 to hold the turbine and a T handle on the compressor wheel to keep from bending the shaft. NEVER use power tools on the rotating assembly.



The following is the turbine wheel from the OPs rebuild pictures, look at how much material was removed from the face of the turbine wheel. It would not surprise me if the seal bore on the bearing housing was also worn (a new seal will not fix this) -



This is what the GTP38 turbine wheel is supposed to look like -



The repair instructions are completely inaccurate and could lead to others possibly damaging their turbochargers more than they already are.

Let alone forgetting the the importance of balancing the rotating assembly!
