im looking to install a supra 6 speed rear end into my carbc i keep blowing my sc400 diff. i have access to a 6 speed supra pumpkin and axels. my question is this does anyone know if it will bolt into the subframe on the gs300. is there someway i can have it welded in there, or would i need a supra sub frame? what are my options also what other parts would i need to make this happen. im not sure about the fitment of the 6 speed i have seen auto supra diffs bolted into the gs300 but i think the 6 speed is bigger and im not sure. any help would e greatly appreciated. im so close to finishing my build after a grueling 5 years and i need to beef upo my rear end. thanks in advance

I did the supra TT LSD diff in mine. Depends on where you are breaking it. I've read the auto cliffs are goof for anywhere between 400-600 but can break any time. The TRD LSD bolts right in and holds 800+. The 6spd diff is bigger but the xmember is the same. You need axles and hubs as well if I'm not mistaken. Also the driveshaft is wrong but Aaron at Driftmotion can help you with all of this info. MVPmotorsports.com has the LSD in stock usually.

6 speed diff bolts right up but you need a left side 6 speed axle iirc.

You don't need no hub , use your stock gs hub it's pnp.

i put down 430 at the wheels on the dyno just over 20lbs and it broke. im looking to go bigger this year with a bigger turbo and wastegate setup. i know im gonna need a rear to hold up. i already have the 6 speed trans and want the six speed to match. thanks for the info. looks like im gonna have to get one and install it.

again you only need one axle the driver side, the right side axle on the na and tt are the same.
