Will 4x11 wheels fit?

I have a friend getting rid of some really nice MOMOs that he has on his Sentra. I believe his Sentra has a 4x11 lug pattern/size. When I tried to research a bit through the net for these wheels I only came across 4 or 5 lug patterns for the sizes, there was no specific lug size mentioned at the sites I went to. Is the 11.7 the lug nut or the opening in the wheel? If these wheels are not meant to fit my car, is there anything I can do to the wheels to fit them without causing too much harm to the car or my future health? Thanks for any info.

I tried to put together a comprehensive wheel page for the G20 wheels and tires.

In short unless it's a new, and I mean 2001 Sentra the wheels won't fit. The older sentras upto the new model change use a 4x100mm pattern. Then new Sentras use the same 4x114.3mm pattern that the G20 uses. Of course the wheels could have 8 holes with both bolt patterns on them, like the ones I just bought.
