Hi guys,
First post so take it easy on me. I own a 2008 HHR SS and have tuned it with great results thanks to all you posts. Specifically COSSOB, IMB, BYT, Daynoff, Terminator2, GMtech, and many others Thank you! Now I'm looking to go a step beyond and currentlly am building my own turbo upgrade. I have the bottom end completed with wisco's, H-beam rods, 82# valve springs, blended heads. Now my question is what turbo? I would like a twin scroll because my goal is 500 hp, and we all know what kind of lag you get with those numbers. I only drag race, but still want to have decent scroll. What are your thoughts?
PS. I'm not a tuner so I will post all of my results, i do this for fun and have no secrets.
