I was using a ACT street lite 11lb flywheel in my old Turbo ZC. I loved the way it rev.ed and was going to go with the same thing. Well I blew the ZC up and now I have a b16. I was going to get the same thing until my friend put the same flywheel in his B16 and it doesn't rev. as fast as my old ZC did even with out the turbo. I was going to go with a ACT pro lite 8lb or Fidenza 8lb flywheel but I know there are some draw backs with going with a lighter then 11lb flywheel like Hp or torque loss and high end I believe. Someone help me decided and shed light on your own experences and what I shoulg go with either a 11lb like before or a 8lb. Also I was going to siwtch from my old ACT solid disc. to a 6puck now anyone here using a 6 or 4 puck on their street car. Thanks.
