^^ Since you said that, I would just leave the R32 / R34 GTR as it is and work on the RB26...
+ Cast Iron is fucking tough.
But that's not the point of this thread...
So...
For 1 of my choices, if I had to choose best of both worlds, I would take my Toyota AE71 Corolla and would put in a Nissan CA18DET or SR20DET...
Make a decent drifter.
Then again, I could just buy a S13 or 180SX.
