Default shot a clip, help me pinpoint wheres the noise coming from...im going bonkers

Hi,

Ever since i did a jdm 6 speed swap, the NVH has increased significantly. i have unabomber sexy rear end, grp n engine and tranny mount, tranny cross member bushing from tic. The thing is, i have all the items when i had the 5 speeder and i DID NOT encounter the same NVH. This is a new thing ever since the swap so i dont really think it was attributed by the bushings. Anyhow, you will notice that during acceleration and decceleration @ 2000 - 3000 rpm, theres a distint loud chatter and grinding sound, it seems to come underneath from the shifter as well as the rear end of the car. Im at my ends and i wan to solve this real bad!
Can a clutch kit cause this kinda noise?
Also, attached is another video of slow speed turns. Also noticed that theres a knocking sound. No idea if its the diff or cv boot / cv joints breaking up on me. It is strange this only happens during slow speed turns...

You sure you have the right gear ratios in there? Sounds like transfer gears to me.

your description could be a little better. Your video could be a little louder.
But from a Scooby Newbie to a Scooby Specialist, it seems like your differentials. Since it comes from front and rear?
It reminds me of mine when I just bought my car used. After an oil change, the sound went away. It only came on in half clutched slow turns.

can a lightened flywheel cause noises during slow speed turns?
When im in reverse gear, it feels like the car is shuddering from below. And i do get a clunk sound from the right aft almost everytime.
