Broken drive blades

[Maj]

ceramic wheel turbos are known to be fragile, and once the first chip came off it would have been out of balance,possably doing the rest of the damage,
damage could have been initiated well before you had it, only needs to be bumped during assembly of the exhaust housing and its a timebomb

look for a gt2554 or a t25g, usually ~$150 on ebay, just avoid anything that the nut on the exhaust wheel looks like yours
