Search this forum for V6 info and the Taurus forum for more V6 info. I would ensure all mechanical normal items are addressed, as reported in this forum as normal wear out with milage so your budget ensures you don't end up with a faster vehicle that won't start, steer or handle when it wants to run with the Big Dogs!! Change all fluids & filters, inspect complete brake system, replace all belts, thermostat, have auto parts store do free check of ignition/starting system. Money spent on go faster parts will be better spent if all preventative maintenance is performed 1st and then it will go when you want it to, consistantly, reliably, and safely! Just a few thoughts from an old hot rodder!
