Who knows what they'll need for their evolution from 6* to 7*. One thing I'm confident about is that Gumi will release a Raid X2 just like Grandt and Elaina. There was a live stream a few days ago and showed us the two different maps that look like Athensphere and the Underworld(?) (correct me if I'm wrong) also it would seem that if they are to get their next evolution, I think they are going to do the same thing like Grandt and Elaina, keep clearing the quest until we get their exclusive evolution material. Which can either be a pain or not depending on someone's luck. Either way, it isn't safe to conclude whether the turbo units are getting 6* or not just to evolve. What we know for sure is, 1.) They're getting 7* forms, 2.) They're getting their own Raid X2, 3.) They'll need at least 1 exclusive evolution material in order to evolve (reason why I'm saying this is because I'm not sure if we need another turbo unit to evolve, and we might need to get evolution materials for the SBS Units from Raid X2 Quests).
