Bigscoot, welcome to Ecomodder! There are many posts on here about the Shell Eco marathon and we have active members that are extremely knowledgeable in a wide variety of areas, so you definitely came to the right place!
Would it be feasible to 3D print a new engine? That sounds like far too much work, but you are reinventing the wheel here!
How hard are engines used in this competition? If they are not used hard enough, maybe that will be enough to make them last longer. As I recall, they only hit 30 MPH and then coast down.
Once you have five posts, you can share links and attachments, so you could reply two times to this thread, just writing:

I look forward to hearing more about your project! Good luck!
