My brothers TT needs a new diff. It has a open center ATM and has twin TD05 turbos so wheelspin is going to be a pretty massive issue.
I have spent over and hour reading up on threads and was just checking to see what our options are.
So far I believe the best bet is an A01B from an NA JZA80. This will be a straight bolt up with the same ratio as a TT will it? Will this be a torsen I or torsen II?
Which cars come with a compatible TI or TII?
Where do I find these diffs and how much should I be paying for TI and TII diffs?
As for after market centers. I would be right in saying these cost around double the price?
