Ok, I just bought a 86 Mustang GT T-Top car. Currently the car has the following mods when I bought it.
1) Electric Fan
2) underdrive Pulleys
3) Bassaini Headers with a Bassaini off road X pipe and 2.5 inch dynomax mufflers with dumps
4) K&N filter in stock set up with no inner fender air box.
5) 16X8 280R cobra wheels with 255/55/16 TA's
Rest of car is bone stock(speed density). Help me pick the best performance parts per dollar to make this car faster and yet be able to take it on a 3 hour trip if needed.

<my car is a T-Top as well> unless your seals are completely leak free.
