I hear you on that! Saturday I tore my project car down to the block, but I have 2 more cars that I still have as daily's as well, so I am lucky to be able to work as I want. My big issue is time!Well my plans just got put on hold. Turbo was damaged, working on getting that resolved, and the my spare car is way further from being ready than originally planned. Good luck with your setup and I am excited to see how it goes.
As far as colder plugs, that's probably a good idea to go a step colder. I don't think I am pushing much more power than stock to require that, but it should probably happen at some point.
Injectors, on other 2020+ 2.0T cars, seem to be the same as the Ranger's 2.3T injectors. I don't see that being a limiting factor yet on 93 octane, even with the Ranger turbo on there.
