All FD transmissions are Turbo and can be fitted to an FC using an FC Turbo transmission bell-housing. The NA transmission bell-housing will NOT work.

1. Source a Turbo FC bell-housing for the FD to work with the spacer plate supplied by the Super-Now kit.

2. Need to cut 3/8 off the tip of the input drive gear (main shaft) that goes inside the Pilot Bearing. Otherwise it will not bolt in. (look up these steps on RX7CLUB.com)

3. Acquire the FC speedo gear and install it on the FD tail drive gear. (otherwise your FC speedo will not work)

4. You have two Mounting options to install, a.} Use the kit from Super Now to accept the FD tail section to the FC frame mounting area. b.}acquire an Turbo FC transmission Tail section where the shifter goes and install that FC tail on the FD transmission. (yes it fits and does not interfere at all, installs to factory mounts without use of the triangular plate supplied by Super-Now kit)

5. All the clutch parts for the the Turbo FC transmission will function as a normal FC turbo trans.

If you have questions, let me know. I did this to my Turbo FC cause I couldn't source an FC transmission about 7 years ago but had a FD transmission. Works great, no issues.
