It's a redtop if that would make any difference? If it was the vct sprocket and left as is would it cause damage?

Its the same thing people just use different things to describe it. Nissans system is called vct or vtc whichever but it is essentially variable valve timing so that's where the vvt comes from.
As Bart said it won't be that if it's a red top.
