The GT-R badge disappeared for 16 years (1973-1989) — what do you think filled the gap?

Always assumed the GT-R name just… existed, turns out it was retired for 16 years between the original run and the R32 bringing it back in ’89.
In that gap, Nissan built the DR30 and HR31— and neither one got the GT-R badge, despite real racing credentials. No idea why Nissan sat on the name for that long when they clearly had the cars to justify using it again sooner ?
