What rearends do I have?

[supraman95mb]

I have 2 1jz supras and they are alittle different

One runs 4k rpms at 70mph. I was told it has a 1jz rear end in it from the guy I got it from.

The other one runs at 2800 rpm at 70mph and I guess it has the factory 7mgte rear end. It also has a R154 tranny.

Thanks guys

70mph@4k is probably the Torsen 4.10
70mph@2.8k is probably 3.73 if the car was turbo before the swap.

Listen to the all knowing stoned kitty. Just don't ask him to do surgery on you.
