    I have run into some hiccups getting my stock 71' 240z up and running after sitting for 2 years (it ran previously).

    I have a stupid question but I can’t get a clear answer. I’m not sure if my 280zx has a turbo or not. Based on the VIN I don’t think it does, but I swear there is a turbo affixed to the engine.

    Okay so I have seen a few post over this but they all seem to be a little over the place so I thought I'd ask about what I found here. I have a 1983 datsun 280zx non turbo.
