Porsche would be able to charge astronomical prices if they used the gt motors and it would help spread out development costs.  This is why it will happen. It is totally consistent with all their previous decisions.  We can revisit my posts next year and see how I did. Been watching Porsche doing this for a long time. That gt motor is the backbone of their franchise so it only makes sense to keep spreading it around just enough to keep interest. I could be wrong but it makes business sense.  The other N/A six is not being used at all any longer. Not likely they will use it in a 718.
