I looked at the online FSM, but I always like to have a book I can read while under the car. Besides, the online versions I have seen to date discuss Australia and European models. So I ordered one from books4cars dot com - US & Canadian models. I don't know how much it costs direct from Nissan (or their distributor), but I got mine for $69.95 + $7.95 S&H to a ZIP in Maryland. No Z enthusiast should be without a FSM, even only to flip through every once in a while, pretending to know what you're doing!!!

Another interesting read is Road & Track on Nissan 300ZX 83-03. Interesting R&T articles and perspective in the Z car. Got one from Classic Motorbooks, $24.91 to my door.

 

"Nissan 300Zx: The Enthusiast's Companion" is also good to get a hold of if you can find it. They pop up on ebay every once in a while.

 

Yup, I highly recommend picking up one. It just doesn't beat having all that info right in your hand.
