flywheel diameter Turbo VS. NA (Searched)

i bought a flywheel that i was told was for an S4 turbo, and when i bought a new friction surface from racing beat for an S4 turbo it is to big. This makes me think that the flywheel is an N/A.

What is the diameter of the S4 Turbo flywheel and the S4 N/A flywheel?

Also, what is the size of the S5 Turbo flywheel and the S5 N/A flywheel?

And how do i identify the counter weight? It says 1029A on the back of the counterweight, what does that mean and which Series and induction take what number counterweight? Thanks!!!

I believe the N/A is 225mm and the Turbo is like 240 or 250mm. 1029A is for the FB's 13b.

are S5 and S4 flywheels the same size? what is the number i need for an S4 turbo? thanks for your help!
