New Here, Looking For Help.

I bought a 1994 mustang 3.8 V6, automatic, with unknown mileage for 1000. its teal in color. ive replaced the motor oil, the oil filter, installed a SR performance cold air intake, and also replaced a power steering fluid transfer line as well. I was looking at another performance modification, but im stuck. Could anyone help me with ideas? Any help would be appreciated

well, considering im on a low budget, im trying to do things one at a time, most bang for the buck if you will. I already have a plan for an H pipe exhaust, but I never gave a thought to a supercharger or the rear gear or the springs.
