Ah... here's the post from another forum (hopefully not blocked)
MyG37 - View Single Post - klonking noise on start up.

See if you can download this MP3 file. This is the same noise I hear on engine start. Unfortunately, this is something I heard every so often before the turbos were installed. At the time I could not find any answers whether this was a serious engine issue or not.

This is a similar noise when abruptly taking foot off the throttle given a decent amount of load in the higher gears like 6th. This is something I've not done lately because I was testing for slippage in 6th at 40 MPH.

I've looked up other videos about rod knocking, and it is a similar sound. Yet, my car runs and sounds fine at with normal or hard driving (other than the test mentioned above). The noise isn't there at idle (very frightening when watching some of the videos on YouTube).

OMG, from G37 Forum someone posted a thread here from Daishi! Haha...
