A few things:
1- My guess is you took a picture of the new radiator cap because it reminds you of a completed project
2- That drain bolt definitely looks snapped. Hopefully that fragment was somehow removed externally and it didnt fall inside. I would blame all that rust on someone using water instead of a 50/50mix. Either way, the rust may also be internal surface rust for water usage.
3- Being that you're mulling over whether or not to keep the delSol and considering the engine rebuild, consider a beefier engine swap instead and take your learning experience to a more fun level to maximize your efforts towards the delSol, making a discernible option to your other car. Buying another engine and the needed components could cost around the amount you might spend to rebuild the current engine.
4- Before you keep sticking on decals, consider buffing out that clear coat to make the paint look as good as it can. Even if you plan to ditch this project, at least that should help resale value.
