need an idea or two.

i bought this 83 280zx and want to know where the best place to get nissan parts for it would be. i also want to know where anyone would think the best place to start with the engine would be.

Nissan dealership, and what do you want to start on the engine? dress up? refurbish? tune up? or do you want to pull off pieces untill it runs like crap?

Hey i think you can find good OEM Nissan parts in the Craigslist , with dealers or may be some commercials but i am not sure whether they sell OEM products but they give it for pretty cheap prices.
