S14 import laws?

[S_Cruthirds]

I was unsure of where to post this so Ill just ask here. Hello everyone. I will be going to Japan in 2016 for the military. In my stay there, i plan to find a s13 or s14(or known as 180sx or silvia). Now i know about the 25 year import rule, but Ive been told a mix of things so maybe someone can help me out. Does the 25 year rule apply to the s14? I know that it has the airbags needed, and the safety features that the s13 and skyline seem to lack just wanted to know if anyone else has heard the same or do you have to wait until 25 year rule regardless. Thank you ahead of time for any help.
