Yes, h4 or 9003 will work and are the same. Silverstars are great, but the bulb life not so much.
Thanks for the info. Is there an overall better H4/9003 lamp than the Silverstars?

Maybe try adjusting and pointing the headlight down more before buying new bulbs? If you like the HID look, maybe getting another kit that has the hi/low function.
It is my understanding that the Tsuru reflector-assembly was not designed for an HID kit. Therefore the results are always less than ideal when putting in an HID kit of any sort (?).
I do like the light output of the HID's. However, I *think* I'll have pretty good results with the Silverstars and a true high-low beam function.
That would be both a better assembly/reflector and better lamp than '93 Nissan stock.
