As I understand it the turbine wheels, and the compressor wheels are milled/machined to each be a neutral balance.
That way it does not matter what aftermarket compressor wheel you get - there should be no imbalance.
Now, unless there are chunks missing out of the turbine wheel causing imbalance or, if a bearing failure has eroded the shaft - yes, you will want to get a new one.
