no, they are all 4.375:1 people call it 4.4 as that is rounded off.
the ones you want are the manual R32 GTS4 diffs which are 35:8 ratio. you must get front and rear and make sure you get all the bits, crown wheels, pinions, the whole shebang. as duncan said to be sure best of getting the whole rear end and front sump. then swap the bits onto your GTR. be aware that doing the front one means engine out as getting the sump off when engine in is pretty much impossible as far as I can see.
front LSD is a good idea while you are there. and also make sure you put the rear gears onto your GTR centre as the rear GTR diff is mech LSD, rear GST4 diff is NOT so you want the new gears onto your current GTR centre.
they are hard to find though! and people who know what they have will charge you an arm and a leg for a complete pair.
Hi i have an r32 gtr and have to replace the front diff i can get a diff but its advertised as an r33 gtr 4.11:1 and my diff is 4.1:1,is it the same or has the guy stuffed up the transaxle code?? i cant seem to find any info at all,just need to no if that diff will go in without changeing the rear etc...Thanks
