What mods next?

I am looking for some sugestions on what mods to do next.I want to get my car to the 13.50 range without changing intake, cam, heads, bore, stroke. I want to try and get it there on bolt ons.I have a 1990 GT 3300 lbs :bang: with dual flowmasters, mac cold air intake, rest is stock.
 
Well, it's not going to be easy, as the stock motor flows like crapola. Bolt ons that'd help would be: headers (1 5/8" shorty), an off road midpipe ( I reccomend a MAC ProChamber), 2 1/2" tailpipes, underdrive pullies, Pro 5.0 shifter (better gear changes on the track), 70mm throttle body, 76mm MAF, and sticky tires. One other thing helps: practice. Also, get some suspension mods first so you don't bend your frame, a nice set of subframes with seat brackets will help, as will a strut tower brace and some good springs. My BBK stuff has done me just fine.

But, best of all: GEARS! get a set of 3.73s and watch what happens. Goodbye gas mileage, hello neck snapping acceleration!
