Hello Richard,
Well the obvious challenge for you is to build your own IC engines!
That said steam engines are more forgiving of minor errors and might be a good place to develop your skills and tackle a more demanding IC engine as a second or third project.

I think I'm along way off from building engines need to learn how to use a lathe and milling 1st but never say never and maybe one in the future
