someone please help me. After installed my turboback i get this bad grinding noise when i change gears. its most noticeable in 2nd. Wat it could it be?

I installed a fujitsubo legalis super r with a jdm spec helix dp. everything went fine, there are no leaks. But when i was jacking up the car to remove the jackstands i heard a loud pop. I looked and didnt see anything and didnt think much of it.

I'm thinking something snapped or somethings caught. or it might be the transmission?

 

check to see if the transmission is rubbing against the downpipe?

 

is it possible to drive it off? as stupid as that sounds.

i also adjusted the wastegate arm to fix the flutter. can the wastegate or turbo cuase the problems i've described?

 

omg. get under the car and fix it. maku is probably right. it could also berubbing against the drive shaft in the vicinity of what used to tbe the resonator. which TB is this?

u may be right about it rubbing. the noise is coming from the the middle of the car mostly on the drivers side. I can feel it thru the pedals. especially when changing from 1-2. could i have broken the trannie?

the tb is a fujitsubo legalis super R mated to a helix jdm-spec dp

 

where under the car did you jack it up? i cant imagine anything popping unless you jacked it up under the tranny or driveshaft. By the way, how do you like the exhaust? I have the same one but with a cusco DP. I also got the Fujitsubo Super Ex with up-pipe.

 

the jack plate. i didnt lift it on the trannie or the driveshaft. i kno better than that.

 

Does it grind every time, or only under hard acceleration?

If you jacked it up in the correct place then something would have to be
really messed up for it to break anything. Sometimes you can get rubbing
only when the suspension is loaded weight. If you can't find anything
when you jack it up, try putting it on ramps and looking for where it's rubbing.

 

found out it was rubbing the transmission xmember. my so called friend who helped me install it didnt put the dp bracket on right.

 

I guess that is better than having a bad transmission
