As for Red Kuri Squash, I've nevr had, so I don't know its consistency or taste.

I'm gonna assume the same amount of volume, but you may have to alter sugar amounts and flavoring slightly depending on its sweetness and potency of the taste of the squash. If it tastes a lot like pumpkin (which it does look like) then I don't think you need to alter it that much, if at all.
