After Orochimaru sealed the leaking chakra he relied on his own power and after almost killing Sakura he continued to do so.
That means every feat he achieved before KCM (not counting VoTE) was with his own power not the bijuu's, only time he relied on Kurama was when he went into rage mode.
But feats like these are from his own power
His body was obviously slightly influenced by Kyubi but as an incarnate he always had monster chakra reserves and would've still reached Hashirama's level without the bijuu. Kurama was a bonus that gave him the ability to surpass the 1st Hokage not equal him.
