In all T5 trannys reverse isn't synchronized, but it does have some sort of device that is supposed to keep you from grinding reverse that someone told me always breaks and doesn't work. There was a post on here a looooooong time ago about it. Don't worry about it man, it just kinda sucks. Put the tranny in fifth and then slide it back into reverse. like eeh1025 said, usually the mainshaft is still spinning and needs to be stopped by putting it in another gear that is synchronized. Also, try this, when you get in the car, put it in first and put the clutch in before you start it, then once it is running, keep the clutch in and bring the tranny out of first and try to put it in reverse. If it grinds, your clutch needs to be adjusted because there is no reason the main shaft would be spinning unless the clutch wasn't fully disengaged. Usually it will grind when you let the clutch out in neutral and then put the clutch in and try to go directly into reverse because the mainshaft spins up to engine speed when in neutral. Make any sense? Hope that helps.
