Nismo Supercoppermix Twin Plate Advise?

[Rezlo]

just set a Nismo twin plate in RB25 S1,

When I pull away I notice it has a mechanical whirring sound, not a clatter like normal twin or tripples,

I know i made 100% sure it was all put together right,

Anyone else had this? or is it a normal sound for these cluches?

Better description of problem:

I am using a Nismo supper copper mix twin plate in a RB25DET S1 with RB25DET matching transmission, Push style obviously, I made 100% sure that I did everything right on install, fitted PLENTY of twin and triple plates before, I chose the nismo unit due to its stock like drivability and low sound,,,, Got the car running, with the clutch in or the clutch out its silent, changing gears with decent RPM matching its silent, but DAMM, on engagement when pulling away it sounds TERRIBLE!!! it sounds like a splined shaft slipping, once engaged its perfect again, Now due to the fact its not doing it at all with the clutch full in or full out all I can rule out any contact from the release bearing onto the PP fingers or the pivot arm onto the actual PP casing, it almost seems like the clutch plates are pucked copper or something crazy abrasive. Besides the terrible sound it feels ok, though I can feel it threw the pedal sometimes. Again I made certain all parts went together correctly, all items were cleaned and all oil/coating were taken off the mating surfaces, Any advise would be great, I am going to start stripping it all out again (real pain because its installed in a S14 right as far back as possible so i have to rip the whole engine out, Any idea's?
