[J2z swap in 280zx]

I'm about to get my first project car I have done swaps before but never with a datsun 280zx or with a j2z 

 

I figured it is the same deal but do I need to make any adjustments for a perfect fit? Or am I over thinking it? 

 

I feel like I would need to weld mounts differently for some reason can anyone tell me if they had this issue come to mind
