Sr20det redtop odd noise

My sr20det swapped 240 has a odd tapping noise. It is most loudest when the engine is cold. It is heard the loudest when in 3rd+ gear between 2800-4000rpm and with light acceleration. It isn't very loud at WOT. The sound is also louder than is the video. It dampened it a little. Any suggestions?
