I do not know which wheel is in my turbo.  I expect the larger wheel (68 mm) to turn a little more slow= ly, since it has a larger surface area to absorb the exhaust, but it should= not make much difference.  Either one should be OK.  The Turbonetics people can probably explain the performance = differences between the two wheel sizes.
