I'm turning my NA into a turbo II. What I need to know is if I put my s5 na flywheel on with 87 rotors and an 87 counterweight, would that balance my motor out? I know the turbo II has more suface to grab, but I'm keeping my NA transmission and drivetrain. The s4 turboII stock flywheel weighs 27 pounds vs my 21 lb NA one. So would it work???????????

 

May I ask why?

 

Its all I have at this point in time!
