Terrible detonation. Probably had bad gas or a bad tune. Example 1 why a "pump gas turbo" should always have race gas mixed in. If you can afford a turbo you can afford a few gallons of race gas per fill.
Need lots more details. What year is the 163? What brand of turbo? If it's an Axys chassis, it might be worth considering. Otherwise, I'd walk away.
That pic alone doesn't tell much. Could be any combination of issues. Maybe just detonation, but maybe a bad crank seal, a bad bearing? How much is torn up? You won't know until you dig into it. So, absolutely expect to buy a long block. That's at least $2k, plus your time. How many miles on the turbo? A turbo sled can take a real beating and a used turbo is only worth half of new, at best. Personally, I'd never buy a used turbo sled unless I knew the previous owner and how they treated the sled.
Maybe you get lucky and only need to replace cylinders, but then you're still stuck with the question of why it happened in the first place. If it's a bad tune, you run the risk of just blowing it up again. If you want a dependable turbo sled, I'd start with a new one.
