300zx twin turbo

its lookin like i might be gettin a 90's 300zx n/a kinda soon but i dont really want a sports car so im gonna see about selling it. has anyone dealt with selling these before and i was more interested in would it increase the value enough to turbo it?
No. The parts to build it would be more than the car is worth when finished. A twin-turbo 300 ZX is the definition of ten pounds of crap in a five pound box as far as the engine compartment is concerned.
