Whats good ya'll,

I got some more questions bout limited slip differentials in the sc300.

1. What is the ratio for a 97 sc300 automatic? =4.27
2. What is the ratio for a 95 sc300 manual? = 4.08
3. What is the ratio for a 98 sc400 automatic? =3.27

I would like to get rid of the 1 wheel open diff and would like to decrease my rpms when driving around 80mph but I would also like it to hook up good of start with good acceleration.

Will a 98 sc400 auto diff fit into a 97 sc300?

Now what would be the best option for me since i have a 1jz swap w/r154 tranny.

 

Yes it will fit perfect PnP, that 's what alot of supra guys are using

 

so is the sc4-- auto diff open like the sc300 or is it an actual lsd? same ? for the sc3-- 5spd

 

It's not an LSD you will have to install your own LSD in there ,that's what a lot of supra guys do instead of spending $950 or $1400 on the auto TT diff.
The SC3 5 speed is 4.08 and is doesn't have an LSD, i think only some of the IS300 came with LSD.
