there are too many variables. it depends on model commodore/falcon as a vn/vp is much lighter than a vt/vx (infact they are about the same weight as a r32), but then the vx will put out about 30-40hp more on a dyno.
if it was standard manual ea falcon (s-pac) vs manual vp commodore, vs manual rb20de, i would say the order would be probably falcon, commodore, skyline. i used to own a manual s-pac ea falcon and they don't actually go that bad. i did it with those models as they are all about the same age.
if you were to change that scenario to late model cars, and add in a magna then the order would change slightly. the order would be something like: magna, falcon, skyline, commodore
