93 gtr has a stronger crank and the pull type clutch than the 89/90/91/92
later in 93 came the V Spec then in 94 came the V Spec II ( V Specs came with 17 x 8 rims compared to normal gtr 16 x 8) i think
Nismo prepped N 1 32 GTR came without stereo air con etc to reduce weight and also no grille in front of the intercooler
