Changing out my radiator so had to take the filter off to get the hoses off decided to take some pictures of the turbo blades. Didn't feel any movement. Supposedly it's a bnr stage 4 can anyone tell the condition based on the pics of the blades wondering why one blade is a different color.

 

Compressor doesn't look like it's eaten anything. That's about all you can tell from the picture.
The paint/coating came off that one fin. It probably wasn't cleaned well enough. Send it!

 

I don't think they are coated, just casting marks, I assume that is material removed for balancing as they have already cut back near the shaft.

 

I believe the white paint is from the balancing process.

Like the balancing machine wants to know what rpm the thing its balancing is spinning and it counts revolutions off the white mark.
