I'll try and answer everybody
Well there is a Toyota Fortuner 2010 with the same engine that is being sold because government won't give papers to ride it legally, so the owner is selling it for parts, however I'm not familiar with motor swapping, for example, how am I sure I will get a good engine?
About the hill, it's a pretty steep hill, this country has a lot of mountains and tropical climate so, geography varies a lot in a few kilometers, however I tried it again (steep hill) and even if I get room to push it faster it will not make more than 80 kms and 4th gear
