So what tranny would be better to mate to my 13btt that im putting in my RX2 a FD tranny or a TII tranny? Thanks

 

Use a TurboII transmission because you can move the shifter housing forward. If you use the FD you can't move it and it will end up being next to your hip makes it a little difficult for shifting. https://www.rx7club.com/old-school-other-rotary-63/t2-trany-rx3-479612/ Explains everything and you will need to use the the S4/S5 style pressure plate it is a push type as opposed to the FD pull type.
