The 745i transmission is slightly different. It has a differnet torque converter and valve package. However your transmission should work fine and will probably hold up to the torque (at least for a days ).
I have built a nice solid bottom end e32 with forged balanced innards set to run 8.3:1 compressions with a rebuilt e32 head custom turbo cam/springs. I have a 745 turbo and manifolds and all electrics I wish to instal in my 86 auto 635 ....... what am I needing to do to make it all John William Waterhouse rather than Picasso .....
