It is highly recommended to get the FD TB also.
Since you're using the FD TB, you can use the stock FD TB tube or get the GReddy aftermarket unit.
It's going to be a PITA to adapt the S4 (or S5) TPS to the FD TB.
It's easier to use the stock FD TPS and splice the lines.
The FD TPS has both a narrow-range and full-range TPS sections, just like the S5 TPS, but the TPS physical design is different.
As with the TPS, the FC TB is going to be a PITA to adapt to the FD UIM.
So...
It's easier to get the FD UIM, TPS, and TPS plug to make this an easy swap.
Keep in mind that a brand new FD TPS is $300+ from the Mazda dealer!
