Sorry if this is obvious for most readers but i'm not up with which models of skyline have what but could you include in the specs:
What drive train? RWD, AWD (ATTESA)
Brakes? 2 piston front 4 piston back? brembo or what?
Has it been over 9 psi boot? if so what horsepower did it give
also how much boost does it allow to be run through it if you know?
I'm going to assume single turbo but you still gotta be sure
I'm new.
