watch out for TT rear ends some came w/ the torsen lsd but alot also came with open diff. if you really want one save up an arm and leg and get the trd lsd. Do it right the first time

I fitted an A02B from a Supra into my Soarer/SC400.

Some people mentioned having to change the diff flange but I didn't need to, mine was identical to the Soarer/SC400 flange.

The diff is a 4.08:1 Torsen LSD and it bolted right up with no drama's.

Great little upgrade, slightly more off the line punch with tons of grip.

The n/a Supra rear ends are 100% compatible with the SC. The TT Auto Supra rear end requires the companion flange to be swapped out. The TT 6MT rear end requires a companion flage swap as well as a new driver's side axle.

To get a new TT Auto Supra rear end from Toyota will cost a mint. Sourcing a complete rear end used is normally $1000. Market value for the LSD unit itself without the rear end housing is ~$250. Installation by a drivetrain shop is upwards of $500 plus the parts cost for new bearings and seals.

it has only costed you $50 because your car doesnt make enough power to break the weld and cause you further grief.

Everyone talks about swapping the whole rear end from a supra. Would be just as well to drop in an LSD for the stock rear end? Do they make them?

This definitely works, although you need to be sure you handle the LSD install with extreme care, perhaps employing a drivetrain specialist to get the job done right. Swapping the whole rear end is a driveway job, which is what makes it so attractive (in my opinion).

Any Supra TT Auto LSD unit will swap as well as any Supra n/a LSD unit (both 5MT and 4AT). The only Supra LSD unit that is non-compatible with the SC rear end is the 6MT TT LSD.

Easiest job is to swap the entire housing with internals.

If you want to retain stock gearing then you need the centre swapped which will require someone to set the diff up properly. The preload and lash must be set which requires someone with experience otherwise you will end up with a pile of shavings.

Removing the housing is pretty straight forward. If you remove it then take both to a workshop the labour cost will be less.

Don't bother with welding your diff. A fully locked diff like this is a PITA to drive on the street and can be dangerous in the wet. Do it properly and spend a little money, you won't regret it.

if you know how to weld the diff will hold up. further grief. do you even know what youre talking about? even if the welds break you can just reweld it again. my good buddy had a 350hp s13 with a welded diff. broke the welds once over a period of year and a half. so if my car made more power it would "costed" me more money to have it done X10

the whole "lincoln locker" thing is a joke. you can use a lincoln MIG welder to weld the diff thats why people call it that.
