Well, considering even without Kurama being sealed within Naruto, Madara's plan would still come into fruition. Naruto, as the incarnation of Asura, would still probably be granted the Six Paths Sage Chakra, thereby granting him SPSM. Sasuke, would still basically play out as the same Sasuke we know, and get the Rinnegan.

Without Kurama to interfere with his Chakra Control, Naruto would basically be a prodigy (Kurama was the driving force of his personality, and how everyone treated him. Without that, pretending to be an idiot would not be in his agenda) and graduate normally from the academy. Due to this, Jiraiya would undoubtedly bring him to Mount Myoboku and have him learn Sage Mode on his 2 year journey, and would have most likely applied nature transformation to the Rasengan. Whereas originally, Jiraiya spent most of their time teaching him how to master his Chakra control, of which he did, albeit slower.

So basically, without Kurama to hinder his progress in the beginning, Naruto would actually be stronger than he was in the prime universe. If by the beginning of Part II he had Sage Mode and Rasenshuriken (and a bigger repertoire of elemental ninjutsu), he would basically be stronger than Jiraiya himself, able to contend with threats seen up to the Pain Arc alone. Also he would destroy Kakashi in his training exercise.

The only difference would be Naruto's personality, as he wouldn't have been shunned by the village, but still understands the pain Sasuke is going through, and still wanting to save him. I believe Naruto wouldn't deviate too far from his original counterpart, and would still have the desire to save Sasuke, and would be most likely more mature.

So taking these into account, due to the plot and the actual nature of who Naruto really is, he would still get SPSM as well as the tailed beast chakra necessary for its Chakra mode to defeat Kaguya. So he may not have Kurama (and the perks he came with), but he would still be as strong as Sasuke. Also, if you're wondering about how he will combat Perfect Susanoo, Asura also had some kind of Avatar mode with TSB's.

Yes, I wrote an essay.

TL;DR: The nature of the plot makes him OP.
