When I first got it, I changed all the fluids (gearbox oil, power steering fluid, brake fluid, coolant etc) and I've changed the oil in it about 5 times in the 12,000ks I've had it. The only things I've had to fix are a master cylinder seal, some suspension bushes, a steering rack boot, and a reverse globe. It runs really well and feels tight.
Never modified mechanically, only mods are aero mirrors, steering wheel and a boost gauge. (have original parts too).
The only reason I'm selling it is because I now have a company car and I never get to drive the skyline anymore. Really hate to see it go.
I'll take some photos of the engine bay tomorrow in the light. Any other photos you want?
