yea...im pretty sure i didn't have this b4... whenever i reverse at more than 1000RPM the engine makes like a weird grinding noise right about where where the passenger sits... more closer to the consol...
im going to get it checked out soon, buh damn dealership near me *****s about mods, so i have to wait until tomarrow to undo all my mods... darn dealer Friendly neighboorhood nissan dealer MY BUTT

 

Are you shore its not outside the car?? The brakes maybe?? And what all mods do you have done to your car??

 

its coming from inside the enginebay, its nowhere close to the brakes, and all my mods are just simple stuff, intake, body kit, strut, and painted stuff here and there, oh and a straight pipe(if you dont count the cats on the headers...

 

Do you have an FSTB?

 

What kind of sound? Does it sound like metal grinding? Or is it a knocking, scraping....?

 

yes i have a FSTB and no its not knocking, its more like METAL gears that dont seem to be aligned right or something, its weird~! starts making the sound right after or above 1000RPM~ im going to have to wait til nex week cuz my teach wont let me open up auto til tuesday nex week

 

maybe check to see if any pipe/or sensor or any other thing is vibrating against a heatshield.
