Default No problem with LSD swap

I had no codes or any problems with the LSD swap. I did have to get a different flange to match the drive shaft. Also maximum speed dropped to about 118 until I tricked the ECU to think speed was lower.

Just to clarify for anyone reading, this is on the 02-05, because they had a 3.29 (I think?) ratio diff from the factory?


For the 06+ it's the same ratio as the Supra/Aristo (3.76), so no issues for me... Just like stock, but more traction, lol.



Side note, I'm getting my remapped ECU on Monday (details in another thread), I wonder if they would be able to set the differential ratio so the ECU is aware of it.

Hey Joe, did they have to drop the rear subframe to change out your diff? Thanks

Honestly, I can't remember now. We had to switch the half shafts to the 02-05 ones to match the diff, that was the big curveball as I recall.

Thank You Sir. You were the only person I knew on the forum who might have done the subframe. Its amazing that there isn'ta lot (OK, Any) information about this. That means nobody has too! Thats great. But not so great for me. 😥

I feel your pain... there isn't a lot of information (any, as you said) on some of the more uncommon things on this car. What do you need to drop the rear subframe for?

The drivers side bracket that the Camber CAM Bolts goes through is bent so the cam can rotate 360 degrees. It plays hell with camber adjustment on that tire.

Have you seen any more rear ends pop up lately. Still a serious consideration for me. Thanks.
