Idk man, 100 shot on a stock 4 cylinder is almost unheard of, at least for more than one run. There are engines built to do it, but I'm sure the cars they are in will be well over $1500. And since almost no one builds for nitrous, those engines are hard to come by.
I started the setup in my 1.6 Lanos with a 35 wet shot. Pretty cool, but not quite right. After upping it to 50, it was feeling a lot better and was still quite safe. I could push it to 75, but that would cause issues, as I've already seen one Lanos motor go at 75 dry shot.
