Z31 upgrades
 

I recently got an 87 z31 and I was wanting to upgrade it for a good cost. The whole works. Anything you can give me I appreciate.

You could be a little more precise about what you mean by upgrade. Just about every kind of mod possible has been done by someone at some point and is probably described in this site's archives. Have you checked them out? :006: Good place to start your shopping list.
