87 mustang gt... I wanna make it faster!

Dont need a bigger 70mm TB till you have ...well the need for it. The stock Tb us fine until you start making some decent power.

I recommend...

Gears-3:73 for manuel and 4:10s for auto is the general rule of thumb.

Headers- SHortys if your poor as am i, or longtubes it you got a few extra$$. X-pipe CATLESS. Your not saving crap by having cats. The whole global warming thing is a crock. We are nearing more of an ice age that happens every so many millions of years or so. Sure we have added a little heat to the fire but all in all its but a drop in the bucket compared to the amout the earth naturally releases.

If you have an Auto get a 3000rpm stall and a shift kit. 5 speed , well be happy with it.

other than that the next moves would be HCI , if your tight on cash probably an intake would be the 1st engine mod to do. A cobra intake can be had cheap and add a moderate amount of ponies. And if you have the $$ for head and cams ...good ,your options are near limitless.
If your a poor boy then port the E-7s and buy an e-cam .

With these cheap mods you can be in the low 13s with some traction.
