Why does the VX sound

[BigSwede]

Isuzu just don't wanna spend more cash to design & develope an stronger and better engine for the VX,

That's not entirely true...Isuzu was working on a V8 for the Trooper, but when it became clear the US market was a no-go, they dropped the program.

I have no clue if isuzu did ever had thoughts of going V8 on any passenger vehicule.

As far as my mech told me isuzu wasn't eager to build any V8 passenger truck.
I neither believe that the VX shall came with a V8 engine,but rather with an stronger,more powerfull V6 engine.

Nissan was able to develope an special 3.5L V6 for the pathfinder kicking 240 PH.
