i thought i saw something that said an mk3 LSD would fit into an sc300 rear diff? did i read it wrong? i tried searching for it but came up with nothing...

so the question is...
would an lsd from a 90-92 1jz powered supra fit in the sc300?

also...
would an aristo lsd work in the sc300?

if so... whut mods are needed and whut parts?

thank you

 

bump...anyone?

 

i thought you were referring to the drug when i first went over this topic

sry, just thought id throw that out there for humor purposes :-P

 

i want to know the same thing. what LSD out there will fit into the factory sc300 diff?

 

dont know if this helps but....


The SC can use the JZA80 Supra's TorSen (torque-sensing) LSD, or the TRD full-time limited-slip differential. The TorSen LSD was offered on the Supra TT 6-speed, automatic, and Supra NA automatics. Each has a different final drive ratio. The Supra NA automatic LSDs are rare since most NA automatics came with open differentials, but if you can find one, it's the only LSD that matches the final drivetrain ratio as the pre-98 SC400 and SC300's 4-speed autos. If you have an Getrag 6-speed transmission and want the TRD LSD, buy TRD# 41301-JA800 to match your final drive ratio. All other tranny types buy TRD# 41301-JS401. Be aware that mix matching the 6-speed LSD with non-6-speed drivetrains will alter your final drive ratio which will affect your speedometer accuracy.

can someone verify that the jza70 lsd or aristo lsd doesnt fit into the sc300?

 

I don't know of anyone that used the jza70 lsd with the SC. Aristo I'm not 100% sure. Im assuming the Aristo is the same as GS300 but again I'm not sure.

 

dang, i was hoping someone could chime in on it... maybe cross reference part numbers?

i ask, because i have an opportunity to pick up the whole pumpkin either jza70 or aristo lsd for a really good price, but im not a rich guy.. so i wanna make the right decision the first time... haha, thanks for ur help everyone... hopefully more help will come this way

 

A direct answer to your question might be found over on the SupraForums, problem searching as that forum search feature is dead till sometime Jan 07.

I'm running the LSD from a n/a mkiv 5-speed in my SC300 perfectly, straight bolt up. Huge help with traction.

 

Don't mean to threadjack, but I wasn't aware the mkiv's came with a 5-speed in any form. Is it the same tranny the 5-speed SC's use (W58 I think...?)

Just curious, thanks!

Yes the NA MKIV's came in 5 speed using the same W58 as the SC's.

 

dang tried searching on supra forums too... damn, i wish it would fit so i can get these lsds... =(

one last chance... aristo lsd into sc300 rear end?
jdm jza70 lsd into sc300???

 

no they dont fit. the mkiii and mkiv are diffrent and wont fit in teh pumpkin.

your best bet if ur cheap is weld the diffrential look at link that says proven power in my sig or next cheapest is a new kaaz 2 way lsd.
