Actually called the GMTU (GM Turbo Upgrade) kit or Stage 1 as it is called in the instruction sheets.
It is a upgrade for the LNF equipped line of GM vehicles. HHR SS, Soltice, Sky.
Adds around 30 hp and 55 lbs torque to the HHR SS.

Traction limited ? Just turn off the traction control and burn the tires off.

 

To Blue Tara, that motor sounds great and I hope you have the best of luck with it....Now tell me how I can get that Beast of a motor. I would like to up grade my 2010 Black SS w/ a red stripe. Any information would be Grrrrreat.

BlackTara was SOLD awhile ago, according to the signature!

 

But you could check out ZZP. Great bunch of guys out in Michigan, they can help you with all of that. I'm still building my wifes SS. But you can check out our project by searching for Project Overboard. I'd link it but I'm my old phone and don't have the patience...sorry

And welcome to the site! Good to have another SS around.
