I just got my '07 civic si sedan today and i've noticed that while reversing, it makes this really ugly grinding/buzzing kinda noise on top of the engine noise. does anybody have any idea what might be causing this? =/
somtimes while going into reverse and then pushing clutch into neutral then shifting to first gear ( while the car is still slightly going backwards ) my gears will grind....

The reverse gear is straight cut (vs angled cut like the forward gears for strength) so it make a whining noise when moving. (probably done on purpose, when anyone hears that sound they know a car is backing up) It also gets no synchros so you cant be moving back or forward at all when putting it into R.
^word. Its a spur gear rather than a helical gear. You'll hear a bad noise if you go in R while moving forward, don't do that. It's normal to hear a mechanical/non-grinding noise while in R and moving backwards just because the whole tooth is making contact at the same time.
I have an 06 si and the only times I ever hear a grinding sound is when the car is rolling back because of the slope on the driveway and I try to shift into reverse while it's still moving. Are you moving when your shifting into reverse?
that brings up an interesting question, what do you do if you're on a driveway or other hill and need to put it in R? do you just put it in neutral and let it roll back?
I don't think so. I wouldn't do that going in reverse too fast, try to stop as much as possible since your clutch has to change direction then get the wheels up to speed.
