Create website in asp.net mvc 4 or mvc 5

It depends on your requirement. As per your question, you should create an Empty MVC project with all the MVC reference.

If you create an "Empty" MVC project, VS will simply gives you an "empty" MVC project which added all the references for MVC.No other files are added extra for this template.

If you create an "MVC" project, it will comes with default controllers and views.

Visual studio however will gives a detailed description about the templates in the right side, it will help you to choose right one as per your need.

select a version of MVC also depends on your need. You can go with either. My suggestion is go with MVC 5.

The below url gives an overview about various templates:
