Not trying to be condescending here.
There's are a lot of great/experienced/knowledgeable and (mostly) "adult like" people on this forum. Along with that, I would guess a pretty wide age range also. They take Z's seriously. So It really helps to be specific when questions are asked. That way, we can specifically answer them.
Pictures can tell more of the story and provide pieces to a puzzle, like a photo of your engine bay could tell us tons of info to begin with without having to ask if it's turbo, v6, inline 6, or even steroid enhanced hamsters.
FB has a few Z pages where people talk all kinds of stuff from coilovers to LS swaps and maybe that's what you're looking for. But it's really hard to get good, reliable information and suggestions there. It's also really easy to get a load of BS info from folks who don't know what they are talking about.
This is the good stuff here.
Also, spell check really helps guys like me.
Your ZX looks very nice by the way.
