FYI there is no room inside the compressor housing for machining and it would not be where it is needed to accomodate the larger wheel. The only place where machining can occur is where the inlet port is and the ebay pic shows stock inlet port and stock housing.

Here's a couple pics of stock vs upgraded wheels. Notice the difference in the size and shape of the wheels and coincide that with which part of the housing that needed to be machined. If the inlet port is not enlarge it will not accomodate a larger wheel.

Also race internals refer to deburring and machining the inside of the housing to smooth out the air flow. Most shops I know take the time to clean up the internals when doing a rebuilt or upgrade.

Price difference for 360 degree thrust bearing is less than $1 so if your shop does not provide the upgrade I would ask for it.
