Adrenalin's & $hawn's sig pictures got me thinking... Just curious as to a few things on a Turbo Combo... ((( No need for Turbo vs. Supercharger or Carb vs. EFI battles )))

What does the position (placement) of the Turbo have to do with the setup? Not height; as I know the snail has to be able to circulate oil successfully and then return it to the oil pan (right?) - but as in location like this:



vs. this:



Then of course I've seen them mounted in the bumpers or between the radiator and the motor, etc.

Why is this? Is each different location of install just for fitment, or is it a certain style kit that puts the turbo in one location rather than the other? Is one side of the engine bay more efficient to use (space, max hp, plumbing, etc) than the other?
