There is alot of things that can cause your issues, you need to pull it apart and investigate.. i have rebuilt the rb25 trans.. it's not very easy to do.. it requires multiple pullers and a press to take apart.. my synchros were actually in decent shape. It was the insert springs that were missing and beat up.. i also replaced all the bearings..
I used a kit off eBay that was made for a Z32. You can get the insert springs directly from nissan.
