Hey guys, I'm tired of open diff and RWD so I'm looking into an Aristo torsen LSD. I've searched around but couldn't find anyone that has done this swap. I'll probably retain the stock 3.26 unless I can locate a 3.76 for cheap.

Anyways, I was wondering if anyone has done this and if it'll bolt up. With the interchangeability of our cars, I am hoping this would work w/o fabrication to the pumpkin, half shaft, flanges, etc.

And please don't make this a thread about "what is a torsen?".

kthxbai.

 

a good start would be to find out what the JDM axle code is and if it is the same a yours, If you read your axle code you will find out that it is an A series.

If the soarer is an A series then you can take the diff (the thorsen unit) aka lsd unit and put it in yours.

In my case i used a A series differential from a USA mk4 auto tt as they are A series.

The axle code can be found on the door or firewall on the vin tag.

 

i found it at a junkyard in Japan so no VIN tag . It came off a JZS161 w/ torsen unit...so I am guessing it'll fit...

 

I dont see why not, the rear subframes are the same arent they? (correct me if im wrong) so it should just bolt up to the regular mounting locations with no problems...

 

Sorry, I should have clarified.

The unit I found is just the LSD, not the pumpkin and the assy. I bet the pumpkin would fit, but I was wondering if the Aristo torsen would fit in a GS4 pumpkin w/ GS4 final.

 

yeah my GS has the aristo torsion in it. My car also started out as a GS4. I believe the rear end came with the swap so they threw it on. I don't know specifics but it locks up good.

 

will any 10 hole lsd from supras work or does it have to be certain years i know the auto is the 10 hole and the stick is 12 holes is there a difference between the two can you use a stick version in an auto as long as it has the 3.7 gears

 

sounds interesting.

 

Nope, it wont fit, just sell it to me for $100 lol...
