Okay heres the deal in january I found out everything in my engine was destroyed out of my 87 Turbo II. Well I began the process of collectiong parts and peicing things together. Well here is what I have so far.A -B- and a -D- rotor from a s5 ,and a set of s5 housings on the way. I then ordered street ported irons which should be here in a couple days. I also understand I need s5 counter weights ,but are there diff. kinds of s5 counter weights??? Also will this work with all my other parts

 

The counter waight is based on series and auto and manul. So a S5 fly wheel matched to your tranny type.

 

so I will need a S5 flywheel? I have a s4 and a s4 manual tranny

 

S5 rotors need s5 front and rear counterweights, tranny doesn't matter. If you have a stock flywheel with the BUILT IN counterweight, you will need an s5 flywheel so it balances properly. With an aftermarket lightened flywheel the counterweight bolts to that, so it all depends on what you have.

And s5 counterweights are s5 counterweights, there's no difference.

 

so all I need to buy now is a s5 flywheel and I'm set right?

 

yea, its n370(IIRC). Plus its also less weight than the s4. You can actually feel the difference.
