My previous tutorials were made in 4.13 I believe, but you have to know that I used the default wheeled vehicle class for these tuts. It is a whole lot harder to setup and require skinning in your modeling software, and the results are not as good as this project.
you can still install 4.14 in parallel with 4.13, this way you could open the project in 4.14 and reproduce it in 4.13 manually.
