My IS300 is a non-LSD version so naturally I'm wanting to make convert it to an LSD as soon as possible. After doing some research, it seems that the clutch style MKIII Supra diff is the way to go over the IS300 torsen style. I'm looking for all the necessary center section parts to make the swap. Since I don't plan on boosting my car anytime soon, I would prefer the steeper 4.30 N/A gear set, but the 4.10 would be good too. Just as long as they are steeper than my stock 3.91's really. I have looked on eBay and found some, but I'm not sure what to look out for as far as milage or potential wear. Pointing me in the direction of a vendor or other site that sells them would be very helpful as well.

No supra mk3 in the states had a 4.10 LSD. The JDM TwinTurboR cars had the 4.10 Torsen which wont hold up well. Well atleast for more than 350hp.
Anyhow you're looking for a n/a Sports opted 4.30 lsd rear end. How much are you looking to spend?

Is the Sports Opted N/A MK3 a JDM only car? I'm reading all over that that is the rear to get for an N/A auto IS300 and they say they can be found for around $200. Any guidance would be greatly appreciated.

Just be sure the n/a car you're getting the rear end out of has the sports option. They usually have a spoiler and the TEM's buttons right behind the shifter. (strut dampening buttons) which will say normal and sport.
I'm still debating myself whether or not to drop the 4.30 in mine or not. I may not and just get the 3.73 and boost my car. Still putting together the puzzle pieces in my head lol

Edit: by the sounds of your sig you have a badass T/A! Looks about where my mk3 supra is. I need to get her tuned badly.
I also believe the IS300 will be tacking around 3250 @ 70mph on the highway.

I figure the 4.10 will get me where I want to be right now in the short run and I'll worry about changing to another gear set later on if need be. There is a good chance I will simply put an LS6 Corvette Z06 motor I have in this car eventually rather than messing with another turbo setup. I want to enjoy the reliability of the stock NA setup for a while though.
That dyno # on the TA was actually when I had a 150 shot on it. It should be putting down over 800 right now but I'm still working some bugs out and the shops around here can't tune for ****.

I think this is what I'm looking for but just want to make sure before I get it. It says "pick up posi G283". Is that it?
