More Power

Just bought a 04 Stratus. I have been doing some research but I am unable to find anything that can help me add more power. Not sure what the engine is right now. I have the 2 dr coupe, I think that it is a 2.7L. If anybody knows anyway to get more power or what kind of engine swaps I can do let me know.

If you have an R/T Stratus than you have a 3.0 litre V6, if it is an SXT you have a 2.4 litre inline 4 cyclinder, I believe the 4 door sedans have the 2.7 litre v6 in it
