It was a VN Calais with the 2L JE camira MPFI engine - they had around 86kw v the 1.6l 64kw - called the Holden Royale. I was sitting there watching it saying 'VN Royale from NZ with 2.0l' as I had heard of it
Cars were pretty expensive back then in NZ (before grey imports they love), so the cheaper 4 cyl (along with perceived fuel economy) probably made sense at the time
The New Zealanders did that from the VH onwards - always had a 4cyl SL/E equivalent 'Royale' - with the starfire 4 up to and including the VK, and then a Nissan RB20 in the VL
