Does anyone know if a 4.7 final drive will go into a JDM Y21 4.4 LSD?
After an hour of searching, I cant find a solid answer. I guess the main thing I need to know is if the LSDs are the same in a Y21 4.4 as the ITR. Thanks in advance.

if what you're trying to find out is: "can i just bolt on the 4.785 ring gear onto my stock diff and go," then the answer is: no. you'll need a 4.785 countershaft to go with the ring gear. if what you're trying to ask is: "will the stock SiR LSD bolt up to the 4.785 ring gear," then i'd REALLY like to know the freaking answer. i think yes, but i wish no.
oh yeah, BTW, nice name. wish i had one like it. j/k, i'm jason, too.

The ring gear will not bolt up to a Y21 differential, you would need a GSR, ITR or CTR differential. I am fairly sure that the B16 LSD is viscous while the B18C/B16B LSD is helical, so they aren't the same.
