This may sound kind of smart-alleky... but it's not intended that way.

In all seriousness I must ask:

1.  How much money do you wish to spend?
2.  What is a major modification in your context?

+ The primary way GROSS horsepower is increased is:

1. Upgrading (rebuilding) existing equipment and engine design supplied with the vehicle.  (This is the biggest issue, and often the most expensive thing to change).

+ The primary way NET horsepower (as in effective torque to the rear wheels) is increased is:

2. Weight.  The less your vehicle weights, the faster it will go with existing equipment.

3. Increase the density of the air going into your cylinders.  Denser air means that more fuel can be efficiently burned during each power stroke, giving more power.  This means installing Ram Air, blowers, or turbo chargers.  Consider also good spark plugs and/or full ingition system issues to properly ignite the fuel-air mixture, as well as proper tuning.

4. Assure that exhaust gasses leave the engine as efficiently as possible.  The harder an engine has to work to push exhaust gas out just wastes horsepower.

5. Proper engine oil and engine cooling.

6. Electronic control chip upgrades.

7. Modifications to transmission and gearing.

Within all of these categories, it's just a matter of how much money you wish to spend.

>>>

Only by rebuilding an engine and/or installing appropriate critical engine parts can the engine actually gain horsepower.

Options 2-7 noted above are often simple modifications to changing things that rob existing horsepower.  And less horsepower being robbed means a net gain in effective horsepower.

Good place to start: A few simple and not so expensive items at these threads

go to installuniversity.com do the free mods in there....you'll pick up 10ish or so....get a lid and do some exhaust mods...catback or a cut-out....you'll pick up 10ish with the free stuff and around 15 with the cut-out if you still have factory exhaust...

then there's always a good tune...the factory programming calls for a very very rich air fuel ratio at wide open throttle (11.5 to 1) get that changed to 12.8ish and you'll pick up good power....
