yes will work, but you have to use bluebird transfer case, gear ratios are a bit different.

the bb transfer case isn't a 50/50 split right?
it's something like 70 front, 30 rear?

50/50, identical to the U12's and the GTiR's

I have a GTiR gearbox in my U12 ATTESA, which was originally an auto CA18DET U12.

I have, GTiR gearbox with U12 SR20DET transfer case with U13 front viscous LSD and housing. Running back to the original 3:7 U12 rear diff.

As long as the transfer case matches the rear diff, your sweet :)
