Stock, if I read that green text right, it says "Miller Cycle"
which tells me Mazda Millenia. The filename agrees.
Miller Cycle engines are interesting: Apparently they use the pressure of the supercharger (the Mazda has a 2.3L V6) to keep the intake valve open during the compression stroke.
okay somebody else post something

Why the heck would you want to *cause* a valve float situation??

Ralph Miller patented his Miller-cycle engine in the 1940s, and for the last several years Mazda has been using this type of engine in some of its cars.
A Miller-cycle engine is very similar to an Otto-cycle engine. The Miller-cycle uses pistons, valves, a spark plug, etc., just like an Otto-cycle engine does. There are two big differences:
* A Miller-cycle engine depends on a supercharger.
* A Miller-cycle engine leaves the intake valve open during part of the compression stroke, so that the engine is compressing against the pressure of the supercharger rather than the pressure of the cylinder walls. The effect is increased efficiency, at a level of about 15 percent

Looks like a VE30DE... 3rd generation Maxima SE.
(VG30'* have different looking intake manifold but look similar as a whole, that'* what tipped me off... what other oldish transverse V6 does Nissan have? The VE30!)

we have a winner
your turn sniper
however, some SEs had VQ DOHC motors....
