i dont know what forum to post this in....
but uh my boy has a b16 tranny with a messed up differential...and i have a ls tranny that works fine...i was wondering can i used the diff. from the ls and put it in the si tranny....
thx

 

yea u can but the diff bearings are different,

 

Just make sure to swap the bearings over. And make sure the case matches up to the bearings.

 

you got to change the final drive too i thought

 

nope, LS and B16a use the same final drive.

 

u must swap the ring gear for it to fit properly.

LS and 99-00 Si S4C tranny both use the same differential with the same bolt pattern. The Si tranny uses a 4.4 (66 tooth) ring gear while the LS uses a 4.266 ring gear.

 

cool, basically im askin do i have to buy any other parts? because i have a ls that is workin fine and the si tranny just needs a new diff. so can i just use everything from the ls? is it worth it for 250 for the si tranny with a messed up diff.?
