Disagree re: r32 plan
Harder and harder to find a r32 which hasn't gone down the cheap thrashed path. It is better to see a clean r32 than some cheap and nasty with power because that power is nothing spectacular so it's lose-lose.
My opinion would be to restore a r32 gtr but 4dr's provide a different view
Good luck with the rebuild, in 5-10years time when everyone has moved on to their family/boring cars you will have something which wasn't discarded because of the cheap thrash mentality.
Similar example; look at all the kingswoods being restored. Everyone looking for shells including the basic 6cyl models.
Tl;dr
