hey,
I got my gsr today and so for I love it. I didn't have any problems with it except for later tonight I noticed when I reved to about 3000 rpms (about where I shift) the engine sounded almost like it was grinding. I thought maybe it was the vtec kicking in, but I don't think they switch over until around 6000 rpms. The grinding was worst when I reved hard, but I noticed a little when i reved calmy as well. Maybe it's just an engine sound that I'm not used to... I don't know. If anybody could tell me what the grinding sound may be that would be great... thanks!

 

does it grind when you shift gears? is it hard to get the car in gear? maybe it's the heatshield or exhaust grinding/rattling

 

ok just to make sure, you were applying the clutch all the way in, right?

 

Problem with many GSR's. The A-pipe (pipe between the exhaust manifold and the cat) has an internal problem that causes it to rattle at around 3,000 rpm. The fix is to replace the A-pipe. Maybe time to buy a header?
