If you are using a Stock TII flywheel you do not need the auto CW.

The flywheel has the CW built in..

Auto CW only used when using an after market flywheel

S5 auto To TII trans swap parts needed:

TII trans
TII starter
Matching series TII flywheel
TII clutch disc
TII P-plate
TII pilot bearing
Custom trans mount, standard Manual mount will not work

Other thing to address:
drive shaft ( mazdatrix TII trans to NA diff)

i have a 6port turbo. my automatic gearbox cant handle the power. Im wondering does the requirements above apply when doing a S5 automatic to S4 TII tranny? or are the s4 TII and S5 TII tranny all the same?

TII trans is interchangeable S4 and S5 so this same is above for you

@hirotary you just need to use the appropriate tII flywheel that matches your series internals to keep it balanced. I.e. if your block has s5 rotating parts then you'd use a s5 tII flywheel, s4 then s4.

Other parts obviously needed are 5 speed pedal assembly, clutch master and slave, soft line (either rubber or braided ss) and you can bend your hardline pretty easily. If your going all out a cluster swap wouldn't be a terrible idea either

found this link https://www.rx7club.com/new-member-rx-7-technical-256/87-rx7-turbo-trans-install-flywheel-questions-871177/. it says using the built in turbo CW will throw off the balance, is this true?
