there's a bunch of Cobalt SS Turbo guys running these cams, they have the same exact engine as us, so technically you won't be the "first" to run them..... just the "first" HHR SS to run them, on this forum.
so you don't know.
the cams themselves may be the same as the 2.4di engine's cams BUT those probably don't have the larger fuel pump lobe..... which ZZP's cams do have and what makes them really special.

Nothing doing, I don't have to buy a zzp cam, there are machine shops in my town and yours too. What is needed is the lift and duration. If you have a trust worthy shop, they can be ground to specs.
