What you're hoping for just is not possible in the real world. Every change you make to the motor has a downside in another area. The real power increases are made by pushing more fuel/air mixture into and pulling more burned gases out of the motor. Now I think you are smart enough to be able to understand that pushing more fuel into and pulling more gases out of a motor cannot result in using less fuel. It will use MORE fuel. This is why race cars get absolutely terrible mileage. So you need to sit down and decide what you really want. If you want power; plan to pay more for fuel and pay far more for repairs (more power will put greater strain on all the driveline and engine parts; and they WILL BREAK). If you get serious about power; you'll probably run out of money for school, so you'll have to drop out of school. The first thing that will probably break is your automatic transmission; which will probably cost $2000 or more to repair.
It is inappropriate and downright foolish to try to hop up a car with over 100,000 miles on it, that has an automatic transmission. This automatic was not designed to last much longer than 100,000 miles to begin with, let along to be used in racing; so as soon as you start putting more power through (or even often driving it aggressively); you'll blow the transmission.
If you can't afford to have a major unplanned expense wreck your life and educational plans; wake up and stop dreaming. Leave this car alone, or it will soon turn into a pile of abused junk. I speak from experience; after having destroyed every vehicle I owned when I was a youth; by hopping it up and driving it hard. Only after I got into a situation where I really had to have a car that I could depend on every day; did I learn to become mature and responsible enough to quit destroying the vehicles I owned by playing with them. I eventually realized that I was not rich enough to buy all the parts and make the constant repairs which are part of the everyday life of a hot rodder; so I then got into economy tuning. That finally was a place where I could modify my engines without damaging them (as long as I didn't set the mxture too lean; which is a constant temptation for inexperienced people who try economy tuning). So I then burned the valves out of some of my first cars in that era before I learned that lesson.
There are some unfortunate people on this site who feel the need to lie about the power and performance they have added to their cars. Be warned not to take all the claims seriously about gobs of horsepower which you read here.
