Just noticed this pic, you won't be able to run those pipes like that. The NX is not as wide and squared as the SE-R up front. When I tried taking my old FMIC piping from my SE-R and put it on the NX, I ran into trouble.
Here's the cold side piping on the SE-R, squared just like yours:
Same pipe setup on the NX:
Front bumper barely fit:
And the lip didn't fit at all. Had to go both sides underneath the lower radiator support.
So just a heads up, nice car and good luck
