FS: Supra LSD + Rear Ends
TRD LSD for an Auto Supra TT is SOLD.
I also have a 3.27 differential from a 98+ SC400. It is compatible with all SC/GS driveshafts and axles (as well as the n/a Supras). I do not know the mileage of this rear end, but it appears in excellent order from visual inspection. Price: $300 shipped
Lastly, I have an SC300 5MT differential (4.08 ratio). It is also compatible with all SC/GS driveshafts and axles (plus n/a Supras). This rear end has a blown differential center, but the ring and pinion are in perfect shape. This would be an excellent pick up for a swap since you could have an LSD installed and not experience downtime prior to selling off your own stock rear end as an offset cost. Price: $125 shipped
Feel free to contact me via PM or in this thread about any product inquiry.

I have already encountered inquiries for the 3.27 rear end via PM. If the unit is still available in ten days, I would be willing to deal it for $275 shipped. But, the unit will probably not last that long at $300 shipped, which is a fair price for such an uncommon item.
For that matter, all PMs habve been replied to.

Regarding the 3.27 rear end and the effect that it would have on an otherwise stock car, I will paste below an account I just outlined for an interested buyer looking to achieve better fuel economy with the gearing swap on his SC300:
"The lower numbered gearing gives you what is commonly referred to as "taller gearing". The lower number (3.27) as compared to your stock ratio (4.08 if 5MT or 4.27 is 4AT) would mean that your revs would drop for a given speed in every gear by 23% if 4AT or 20% if 5MT.
The effect of this lower gearing would definitely increase fuel economy on the highway. When cruising at a constant speed, the effect of the gearing change to fuel economy is most obvious. The car would cruise at 80mph as fuel efficiently as it currently does at 65.
While driving around town, I would expect to see similar fuel economy to what you do now. When accelerating, the lower numbered gearing of the 3.27 rear end would actually put the engine under more load. That being said, my Tercel is a base model and not the DX. The base model had a slightly lower numbered gearing than the DX model (3.526 vs. 3.722) to lower the 0-60 time on the DX model. My base model advertised 2mpg better in the city (and still does ~36 in the city, which is absurd).
As for performance, you will definitely lose a step. The 20% or 23% lower rev numbers that I quoted would also mean that 20% or 23% less torque was reaching the road. Your car that currently makes 225hp and 214ft*lb of torque would feel like a car making 225hp and ~175ft*lb of torque. The gearing change will not alter horsepower production, but it will alter the amount of torque that reaches the road. Most notably, first gear will be rather underwhelming. Once you are rolling, the car will feel relatively normal since there will be more gear ratio options for the transmission to utilize."

For turbo guys, the key line to extract from the account above is "When accelerating, the lower numbered gearing of the 3.27 rear end would actually put the engine under more load."
More load means more air/fuel mixture is being burned, which means there is more exhaust volume and more exhaust gas velocity. More exhaust gas velocity means faster spool up time for the turbo and more revs in boost, thus widening the perceived power band.

Bump to the top.
If you are interested in either rear end for the purpose of an LSD swap, I would gladly unassemble the entire piece, putting each item in a labeled bag so that you could save labor at the drivetrain shop where you were having the LSD installed. That way, you would only have to pay for assembly and not unassembly. In either case, I would knock off ten bucks from the price for this since the shipping would be a little less.
