Hey guys was just wondering if the turbo 2 tranny out of an s5 will bolt onto an s4 na 13b

 

not without either a custom driveshaft or swapping out the driveshaft, diff, and axles with it. It will bolt to the motor though.

 

You would need an S5 turbo flywheel and clutch also. Mazda trix make a drive shaft for turbo tranny to na diff.

 

I have already done it. Here is a COMPLETE parts list.
Tranny, starter, clutch slave, flywheel, either a custom driveshaft to mate with the LARGER t2 output shaft. OR the mazdatrix unit as mentioned above. That was my choice. OR complete the swap with a t2 D.S. and T2 rear diff/axles.
