So, I got a 2012 Mazda 2, I see all these cool things you can do to them but idk what to do or if it’s worth doing, she runs good and everything but has 135,000 miles, I want to do something to add more power but don’t know if it’s worth putting money into with that amount of miles, also don’t know what to do, the only thing I could think of would be turbo charging it but I thought maybe one of y’all might know a specific turbo or maybe something else I can do to get more power from the engine
