Welcome to Nico!
The top timing chain guide on the KA will cause rattles.
Nissan suggests that you take it off.

That's the guy right there.
You should also check out the suspension bushings, those will eventually go due to age. Check the steering rack bushings too.
I highly suggest replacing the tension rods with aftermarket ones. Replacing the rubber with a solid rod end will make the steering and braking feel much better.
Also, since these cars are pretty flexy, I found that the Nismo Power Brace or Jonnie Fraz/Stealth Fab tension rod braces help the feel of the car
a lot.
You can find a lot of the articles on these replacements and installs here on Nico. Just do a Google search for them.
Here's the steering rack article:

And and article for all the timing chain guides:

You don't need to delve too deep to try and replace the others, the top guide is the main offender.
