I know that everyone knows how under powered the 4 cylinder tacoma is. I'm ok with it for the most part but when i'm driving in hilly areas it becomes a task to keep up with traffic. I can't help but think that a 2.7 liter engine should be capable of well over 159 hp. Hell my Mazda 3 that i had before this made 160 with 2.0l.
I guess my question is, is there a way to significantly increase power without with out a going forced induction? Of course the regular thing such a intake and manifold as well as exhaust and the manifold that goes with that. But what about rocker arms and spring replacement? injectors and a remapping?
My knowledge of this engine isn't that extensive yet so i ask you. Any information would be great. Thanks
