Here's the re-build for my Fiance's HHR SS. Stock turbo is still in. Only replacements are inter-cooler (2x's size of OEM), and pulled all plastic pipping for 3 in stainless. They tested up to 24 psi but that wasn't a good idea b/c the pipping put a slight dent in the hood from the inside out. So the boost is turned down to 20psi. I have to admit these Ecotecs can push. Oh there's the tune...
I'm sure he's got more up his sleeve.

Dude last night said he was pushing 23-25psi...but his no-lift-shift function wasn't working because of a different blow off valve, so he dropped into vacuum during shifts. So that may have been his only disadvantage during that race lol.
