98 yellow gt

hi i am new to this community i have a 98 mustang gt stock 4.6l
i bought this car years ago i liked this body style and decided i wanted to have a car that i can build up as much hp and torque without doing an engine and trans swap, but still want this as an everyday driver with a/c. since i do not know the best way to go about this i am hoping some of you gear heads can help me without spending money i dont need too. i want build it up slowly but i want to do everything once and not have to rebuy same upgraded parts later. heres my example of what i am reffering too : i only have a k/n air filter installed and have bought but not installed 373 gears because i was told to change from a 28 spline to a 31 spline and i know thats about $800 extra by time buy everything else is it worth it or not. i was looking into superchargers as well please help thanks.
