Sorry to hear that, Mark! I got rid of the other S400 about two days after you got yours. This wheel is one I got for a friends turbo that needed a wheel. As usual, that project never got finished and I'm sick of this one cluttering up my bench!You parting the other one out? 'Bout 2 wks after I got that S472 from you my motor in my puller decided to tell me it wanted rebuilt. That turbo's sitting in a sealed bag in my garage on the back burner.
