EDIT:

Looks like N54 & N55 engine owners should be scared too, according to Mr. Radowski's website:

And another, but Gintani doesn't mention N series engines:

For whatever reason it seems less likely to happen in N54 and N55 cars. Maybe because they make less power stock, but there could be other factors that contribute.
