although possible, it is not recommended. The actual cast engine block is the same however, the intake manifold and exhaust manifolds are to wide to fit into the z31 engine bay. So it is possible but would take a good amount of custom fabrication.
I'd recommend an sr20 or rb series motor swap. considerably less modification
with your back to the engine its on ur left side under the exhaust manifold
300zx from 84 - 88 are z31
222hp
The 300zx is a very particular car. It depends on where you get the computer from. I have swapped a non turbo to a turbo with the same engine except my new motor was from japan. the computers were slightly different, but nothing a little modification wont fix. As long as you get a computer off of a motor that is the same model as yours, it must be from the same model, several years have the same model (1984-1986) then you should not have any major problems.

Yes they use different fuel mixtures and injector sizes
If you are looking at the engine look to the left of the engine. Your fuel filter is connected to the frame with a strap.
