Port Fuel Injection.
According to the Unofficial Holden Commodore Archive for VZ, all engine variants have electronic sequential fuel injection.

The above archive doesn't mention engine RPO codes, nor does it specify that fuel is injected into each intake port.
But port injection and sequential fuel injection are not the same thing according to this article.
So, it may be that calling it port injection is wrong ;)

I like this article. I know from working on them that the alloytec has 6 injectors. If the article is indeed correct then the engine is a MPFI with SIDI. How did you find it?

VZ does not have direct injection.
VS series 3 onwards is sequential injection from memory it may be all VS models? VE series 2 was when the first sequentially fired direct injection engines came out.

All sequential injection means is that the injector fires on the intake stroke of the cylinder. Before this it was batch fire wherw the injectors would fire mutiple times accross all 4 strokes.
