ON3GO,
What kind of money do you plan on spending on your 240Z? If I were you I would get I car before you start geting parts for it. Find a Z with little to no rust, and see were you need to put money first, brakes, ball joints......
The part I would be looking for now if any, would be the turbo motor. Put that into the car and start from there. All the fun parts ,turbo timers, boost controlers, seats eat up a lot of cash that you could put into an R200, 5 speed, you know parts that you need. Then buy the toys.
Just my .02
