Engine mods?

I currently have a 01 taco with a 2.4L, i have done quite a few things to the exterior but want to do some more to the engine. I put a K&N air intake on it and a magnaflow muffler, and that is it. any suggestions? throw me anything

 

Are you looking for power... or? just ways to waste money?

Supercharger or GTFO.

But.. You can do cams, header, electric fan will free up power, port/polished or bigger intake manifold.. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ How much do you want to spend?

Every 1 HP = $100 give or take.

 

im looking for some power, i was considering turbo/supercharger, larger throttle body, headers ect
