your first mod should be lose the stock tranny cooler in the radiator and install an aftermarket one... you want to avoid the PINK MILKSHAKE at all costs. (search "pink milkshake" if in doubt).i would also say do a good full tune up -plugs, wire, o2 sensors, filters(all), fluids(all- coolant to rear diff). then from there you will probably have done enough reading on the forum here to get some good ideas on what you want to do next, ie lift, lights, bumpers, tires, motor, brakes, wheels. interior ect.
