Just got a great 90' LX...now to make it faster...?

'90 LX's, in my opinion, are the absolute BEST stang ever . Go w/ the gears first, definately. Remove your air silencer, put in underdrive pulleys, and get a new shift kit (Pro 5.0 or Steeda Tri-ax). BFG Comp T/A's have treated me really well. Then, you'll be coughing up a little more cash (heads/intake/headers etc etc)
