If you were very nice to it a T series diff MIGHT last behind your motor, but given you have done some work to the motor I assume it will have to earn its keep.
Do a search through the forums, there are a number of options discussed including G code, F code, borg warner etc all of which are possible to get with LSD and will handle a bit more than a T series diff.
