Makes sense. I just don't know enough about the dynamics of a turbo to ask... keeping in mind I don't track my car... would it make sense to get it balanced with that little knick in the blade? I actually sent an email off to IA to see if they sell jus the blade.

Craig, in your last picture, if you take the larges gouge in the center, there's just about that much taken off the corner (cold side though), maybe slightly less.

i wasn't sure you could buy just the blades, and also, wondered if you could upgrade at that point? (K27 7200.. or so I think)
