ok first I dont have a turbo but i figure its the same pulley. right?
but I do have that common problem of the crank pulley coming apart .
Im looking at this not really as a proformance thing but as it will never seperate again.

question is would I notice the crank not having the rubber dampening? would it shake at idle or something?

 

i can not say, about the shaking...but i suggest you just get the OEM pulley, new of course.

 

I would stick OEM.
