Great, did you change your oil? I would recommend changing your oil and taking apart the old CHRA to inspect the damage to the bearing system. That will give you an indication of how much metal got into your oiling system. It is possible the damage was just FOD and the oiling system didn't get contaminated. I would also recommend checking axial and radial end play of the rear turbocharger to see if any damage to the bearing system in that turbo has already occurred. It should feel similar to the new front turbo you installed. Also, CHRA stands for center housing rotating assembly. The CHRA with end housings is just referred to as a turbocharger.
Yes I changed the oil, oil filter and front turbo oil feed and return lines. I checked the rear turbo and it looked mint with no serious shaft play. I believe most of the metal shrapnel from the failed turbo ended up in my intercoolers. I flushed them out, along with most of the intake system.
I know what CHRA stands for and used the term correctly. I initially planned on just swapping the CHRA but when I took the old one out and measured it, it wasn’t the same as the replacement CHRA 3SX offers. So I contacted a member on here and bought a complete used 9B turbo and swapped the whole assembly in.
