Nissan H20-II engine?
Set cylinder #1 (closest to fan) at TDC of the compression stroke.
Then, you will have to fiddle with the oil pump drive slot to align it just right so that when you drop the distributor into its hole, the distributor rotor points to the #1 cylinder spark plug tower on the distributor cap.
That will get it running but you still need to use a timing light to fine tune the ignition timing.
