Thanks Jim,
And everyone else that gave good advise and commented on the Question. There is interest in the 0-200, 0-240's, 0-235's and 0-320's, so it is good info for decision making. The 915 turbo empty weights are comparable (?) to these other engine options, and seems to be a few of them around for rebuilding IF , one chooses to do so. Almost twice the torque at half the RPM. Thanks again for all your input. billy
