Rattle at 2500rpm

Joepro · 08-21-2013, 10:34 AM

What exhaust are you running? I was chasing a vibration for a few days in the 3000k to 3500k rpms, turns out the tiny weld on the front flanges of my FI exhaust was cracked. wized the weld out, noise gone! If you feel it in the shifter, phunk got it right, its gear lash, the 350z was even worse.

I do know that noise. This is a slightly different noise and it only started happening after the turbo was installed. This noise is loudest when cold and when its warm you cant even hear it. It never happens at idle only between 2-3k. Any other ideas? I dont get into boost until that noise goes away
