I pulled the motor out of my car to do a fresh rebuild since I found the timing components on the brink of killing the motor. Everything looks good and clean, crank and all the bearings look great with no significant wear for being 24 years old. My main question tho, is it possible to replace all the bearings and slap it back together with new bolts without having to take anything to get machined? I'm not completely sure what route I'm going yet, but this will help in that decision. Thanks guys.
 
Clean it up, check the crank with a micrometer, hone (deglaze) the bores and put it back together with new timing parts, water pump and maybe an oil pump and valve job while you are there for a long life.
Prep is 90% so it needs to check out and be clean.
My DD Saturn DOHC motor went down with 2 chipped valves (don't know what happened but drove it home), tore it down, did a valve job, clean and hone, put all new bearings, rings, oil and water pumps along with timing chain components and it has 32k on it now. Same thing you want to do.
 
I did a half assed rebuild on my Eclipse in 2018. Didn't even pull the engine. Just rod bearings, rods, pistons, and associated gaskets and a quick once-over with a hone in the cylinders. You're not throwing anything crazy at the engine with your 16g so I don't see a reason to go all out if you don't want to spend the money on a more involved rebuild.

But yes, measure the crank journals and get the respective bearings. I wasn't really thinking about that when I ordered standard bearings for mine and they ended up being what I needed but I could have made things a lot worse than not doing the rebuild at all

Yes, Just replace those timing components and throw it back together.
