Syncro's are wear items and should be changed.
Depending on how the car was driven, specifically whether you or the previous owner was any good at shifting and not abusing the syncro's, whether anyone bothered to change the transmission fluid, check the level or let it warm up before driving it hard.
This is the same basic transmission that was used in the older 2.2/2.5 turbo cars. My CSX has about 140K on it and while the bearings are starting to complain, I've just started to notice significant wear on the syncro's, mostly due to overzealous autocross driving.
I've already bought the repair parts I need to build up a spare and swap it in. They really aren't hard to do provided you can come up with an FSM and can set aside a weekend to do the work.
