The engine is a 4 cylinder. It has approx, 110,000 miles on it. Is there anything else I can do to add a little pep to the car?
the car has a 2.4L engine is there any way to add some power to it i'm looking for pep any ajustments I can make or add a turbo or supercharger ect.

Check your air pressure in your tires regularly, remove any access weight. Make sure you're using proper oil during oil changes. New air filter, fuel filter. Add fuel injector cleaner to your fuel tank every oil change.

proper maintenance is all that is worth doing. You have 167 HP and 185 Lbs of torque which with that engine and weight of Toyota is plenty. If you add turbo or supercharger you will either blow up engine or spend besides turbo another 5-7000 on mods needed to make worth while. If you install without mods you will end up with hardly any gain.
