Hard to tell if no mileage posted.
You won't get back what you spent on your mods so getting it back to stock if you have the old parts will get you some money back even if you spend on labor to take it out. There is some pay off. It will be hard to sell to a dealership or some private party who does not know anything about the mods. If you don't want to part out, expect to either lose your shirt on your mods or wait for a while and find someone in the forum or on the VQ or Nissan FB pages to find a buyer who knows what you put in.

As you know, people here will buy your gear like:

Fast Intentions Twin Turbo
Stance Coilovers - if low miles
20" K3 Project wheels - if no curb rashes and is straight
Ark Grip Exhaust System - for the right price this has pretty much low value.
Specialtyz clutch and flywheel - hard to sell this on the car because of the noise unless you get a buyer who understands what it is and not worth taking it off the car.
Mines CF Wing unless it is screwed in.
SEIBON Full CF ground effects kit - depend on the kind of kit and if in good condition. If the S tune replica, it will be a hard sell.
CF Nismo shifter knob
HKS Boost controller
AEM air/fuel ratio and Pro sport gauges on dash and a pillar
CF diffuser - If Fuji, it will sell quick.

Good luck.
