The reason why the 430 goes bad is because the front pinion seal is a known fault in these rear ends. I'm waiting on getting a 3.76, so i am just adding fluid every few thousand miles just to be on the safe side.

After a few days of driving I have noticed this......this is by far the 2nd best mod I've done so far! The best was BBK! I found out what the poping noise was.......I put it in without putting the top bushing on the front of the pumpkin......
it was creating a small vibration which is all now gone! Luckly all I had to do was take the front two bolts out and slide in the bushings! 
AWSOME MOD! RECCOMENDED TO EVERYONE! This is how our cars should have come from the factory!

guys, there is someone local to me selling a torsen type lsd. According to his description its a helical (torsion) limited-slip differential for MKIII Toyota Supras. These were not available for the US MKIIIs and I believe they only came in the JZA70 MKIIIs. Its not the entire pumpkin but just the internals. Will this work in our stock rear ends if I swap them out? Is this the same gear ratio as the 3.76 ??

that should work.....but I would take it to a shop that really knows their rears(if you know what I mean) just to make sure. There is a thread somewhere I just can not find it at the moment, but It's a DIY about how to do just this type of install for cheaper than buying the whole pumpkin! I know you need a press to get them in there correctly! GL with that! I didn't want to go that route bc when I want to sell my ride it's easier to remove the whole pumpkin!
Have noticed a small difference in mileage.........maybe it's because I have been keeping my right foot on the floor!
most say it's about a 2-3mpg difference. well worth it in my opinion!

well the install im not worried about, I just want to make sure its the right kind of lsd and that it will work in our stock pumpkin. Also how do you determine the ratio? The seller does have a part number off of the lsd unit if that helps in anyway.

that's just the LSD. I don't know if it fits, but if it's the same as mkiv tt auto, then yes it will.

I used to own a mk3 supra and I'm pretty sure it won't fit due to the axles having a different spline gear on them. I remember a supraforums member did the swap and added a mk4 supra diff to his car & he had to have custom axles made consisting of mk3 & mk4 axles. It will fit in your diff case but you too will have to have custom axles. You may also want to check the supra forums for yourself I do recall those torsen diffs wich only were available on jdm jza70 supras are not that reliable under high horsepower applications. I personally just go with the mk4 diff plenty of members have driving on them.
