So I recently blew my ka up, again. The same day it went I was told the rb25 flywheel isn't balanced correctly for a ka and will cause it to destroy bearings. This is the first I've heard of this and it has me a little paranoid. My ka didn't go in a normal manner. Rod bearing number 3 was absolutely destroyed but didn't spin and no visible damage was done to the crank. All tolerances were spot on when it was assembled. I'm throwing my turbo setup on another long block so I want to figure out if I need to get rid of this setup or not.

Thanks!
