I do not know which wheel is in my turbo= .  I expect the larger wheel (68 mm) to turn a little mor= e slowly, 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 perfor= mance differences between the two wheel sizes.
