   Hi guys,
   I’m building a turbo set up for my C2 and was wondering what power the vts cams are good for and how the standard valve springs stand up to boost?

   For sensible boost levels the stock springs are fine, because the motor won't want to rev as high anyway.
   The springs are marginal from 7000 really, but you'll find that, if your turbo is correctly sized, that you'll want to change up around 5500-6000 rpm to use the torque available.
   What turbo hardware are you using?

   I think it’s just best to change them for something beefier then
