I forgot what were the difference, or was there even one?

but its showing different part numbers, so I assume there is a difference ?

reason I ask is because I'm undergoing a JDM 4AT to 6 MT swap, I already got the exhaust and PPF off, if I wanna swap the diff I should do it now, and I can't remember if there is a difference between the 2, it's different part number so I assume there is a difference.

 

The 6 spd will fit the LSD, the 4AT will not and doesn't have one

 

hmm? so can I swap a 6mt Torsen LSD in place ?

 

You can swap in the entire diff assy with LSD from a 6spd, direct bolt on assuming you used the 6spd driveshaft too

Edit: i think you may need the entire rear end axles & all

 

Hmm okie,

holy ****, u can't be serious ...

 

just pulled the EPC and check,

sub frame is the same

car already have DSC

the LSD I have is something not found in USDM RX8

Anyway, thx. I'm gonna look for the difference.
