I have a used (86k) 2019 mirage 4-dr (non-hatchback) and I have 2 goals for it, possibly 3):
-turbocharge it/engine swap/air filter upgrade/etc
-as fuel efficient as humanly possible even though I have the best version I could for a 19’ already
-if I don’t sell it for a project car when I have the money, I would be upgrading the hell out of it and want to know what CAN be done

My original project was a 92’ civic, what customizations can’t I do on a 19’ or newer mirage that I can do on a civic?
