Yes, you can use the NX wet kit on any model car really. The 98 will accept it fine.
I actually just picked up a NOS kit for an uncredible good deal and will sell it to a ricer for more than I paid and will be getting the NX kit with all the goodies to go on the car before our next track day for sure!
I would stay away from the dry kit IMHO and go with the wet where you know that there will be fuel there when it is needed.
