Spinosaurs will win because it was much larger and heavier than the Indominus rex. bite force doesn't determine the winner of a fight, it's indeed a factor but much less than being much more massive.however, if it's the same spino from JPIII then it will either lose or win and die after the fight.

and T.Rex can't kill everything he grabbed it's neck because if he doesn't grab properly the second creature could just shake him off and injure him badly in facial areas like the neck.

and as for JPIII neither Spino nor T.Rex were adults, and the reason why spino was able to survive the bite of the T.Rex if because young  T.Rexs or even sub-adults' teeth are thin and sharp, which means they can't apply pressure or actually grab good. only adult Tyrannosaurs' have the famous bone-breaking teeth and powerful bie force.
