Well, I've been thinking about the whole Zeo to Turbo transition a lot, and I think I've figured out why the Zeo powers were put aside. From what I read here on the wiki, the rangers needed their Turbo powers to follow Divatox to Muranthias so that they could try and stop her from awakening Maligore. However, after that, the rangers continued to use their turbo powers because they were better for combatting Divatox's various detonators (as shown in the first episode arc, Tommy wasn't able to disarm the detonator, but thanks to the arsenal that came with the Turbo powers, he was able to send it where it wouldn't cause any harm). Then, after Tommy, Adam, Kat, and Tanya left, there were no Zeo Rangers left on the team. It's extremely possible that nobody knew of the Zeo Crystal's presence in the Power Chamber, since Alpha 6 and Divatox didn't arrive until after the Zeo Crystal was retired. This would explain why, after they lost their Turbo powers, they didn't simply re-use the Zeo Crystal. It's also possible that, years later, Tommy met up with T.J., and they could have gotten onto the topic of the Power Chamber's destruction. Tommy would have realized then that the Zeo Crystal was just lying in the ruins of the Power Chamber, and he could have then retrieved it from the ruins, which would explain how he got his Zeonizers back in Forever Red.

So, what do you think? Keep in mind that I never actually watched Turbo: A Power Rangers Movie, so I'm not 100% certain as to whether or not Justin knew about the Zeo Crystal.
