Does anyone know if in 2010 they switched the supercharger for a turbo?

HHR SS was always turbo.

Hoping to clarify a potential source of confusion:

HHR Cousin Cobalt stopped offering superchargers for 2008-2010, when the boosted Cobalt SS went turbo. All HHR SS's (2008-2010 only) were turbo. Engine RPO was LNF. Had much in common with those turbo Cobalts, dubbed "LNF" in the Cobalt community, to distinguish them from non-turbo Cobalt SS's.

So there has never been a supercharged HHR from the factory. A few na's have been upgraded. I would love to find a nice 2007 HHR 2.4 and retrofit a blower.

So, the answer is "no" nobody knows if they switched from SC to TC in 2010 because A. they didn't and B. there was no SS in M.Y. 2011 (made in 2010).

SInce it seems like someone here might know the answer, is a late supercharged version a good engine to use? I have the chance to get a zero mile leftover one for a project for a good price if it's a good choice? It would be going in an older Jeep pickup which came with about 60HP and I like the size weight and power for that application. But of course, not if it's got issues.

An Ecotec 2.4 supercharged engine is great for that project, make sure it’s set up for a rear drive configuration.

Might be referring to the 2.0 LSJ.

I think the supercharged one I'm talking about is from a Saturn. Purchased from GM to use as a dyno mule for supercharger development, but while they purchased the engine, the project was canceled just after they finished the baseline runs and it's been sitting on a shelf ever since.

The Saturn Ion Red Line Edition, 2004-2007. It used the LSJ.

But was it front wheel drive or rear wheel drive? The oil pan and pickup are different, you could get a those from a Saturn Sky or Pontiac Solstice.
