Hey man,
Okay so I dug deeper, I think you're right. No wonder I couldn't find anything, I was searching 280zx 1978.it doesn't even exist lol
I found a guy selling a z, so I asked him if it was the 280zx and he said yes, I asked what year he said 1978. So I'm a newbie and new to the z world, but luckily I kept doing more research cause I think he's trying to pull one on me. He sent some pictures of the car and engine, hard to tell if it's a 280zx but I think it's not a 280zx and the engine I can't see the turbo. Is it okay if I post the pictures here and you could double check for me?
