How much HP would this add?

Also, around how much would this cost?


I'm currently standing in line for the 4x2 diesel Fortuner which is *rumored* to have the same engine as the Innova. If that's the case, then it'll have around 102 HP.

I'm just planning ahead.


OR if you have any other suggestions on how I can beef up the 2.5 (Innova's) engine, please feel free to post.

Thanks!
