92 Mustang LX 2.3

[92LXcoupeNoob]

I have a 4 speed automatic LX and I want to do an upgrade to it because I find that I could really use a little bit more of everything. Before you start talking in a foreign language, I must note that I am a first timer (This is my first car, im 19 yrs old, uneducated on mechanics). My car is completely stock under the hood, despite that I have done a regular tune up recently and have a brand new starter. What can i do to add more horsepower, torque, and/or mpg? Ive gone to Autozone and they suggested an aftermarket Air Intake but how and which do i use? Also I thought about performance modules/chips to give it a boost. What can I do to make my 2.3 lighter, faster, and economic?

Stock header from a 2.5L (same engine family) Ford Ranger, remove the air intake muffler (attached to the front of the air box). I believe that the 2.3L may have 19 lb/hr injectors (not entirely sure), so you may be able to try a mass air sensor from a 5.0L... haven't heard of someone trying this, but it would really open up the intake.

Gearing is a HUGE difference. I have a 2.3L with 3.27 gears and swapped for 4.11 gears.... wow, made a huge difference. Having an automatic sucks, but gearing really livens it up and you can get them for not too much money.

Biggest modification, REAR SWAY BAR. It makes by far the biggest difference in a 4 cylinder mustang, it will handle SO much better.

There's a bunch of other stuff, but these are some ideas to get started.
