2007 Chevy Cobalt SS Turbo Install Part 2 - Transportation Transsformation - Tech

'07 Cobalt Earns Super Sport Nameplate, Thanks To Hahn Racecraft Turbo System-Part 2 Of 3

GMHTP's editors walk a fine line when disseminating edgy, "alternative" high-performance information to readers. Some embrace the idea of modding up something other than an F-body, and consider the occasional story thereon a breath of fresh air. But others-especially when one trods into the realm of four-cylinder performance-shut down completely, insisting that any ride sporting less than eight pistons represents a frontier they'd prefer to not visit.

Those of you who resisted the urge to tear pages 60-70 out of our July issue (and, presumably, use them for some unmentionable purpose) know that we have been trying to come up with an amicable solution to the stress test that is driving prized GM iron on a daily basis. We think we may have one excellent answer in installing a Hahn Racecraft turbo system on a 2.4L Ecotec-powered Cobalt SS. Speaking personally, I'm not demanding that you share views on the importance of reducing your carbon footprint and cutting our dependence on foreign oil, but I think everyone can appreciate the need to save some dough on today's record-priced fuel-and the need to not fret about your Trans Am getting rear-ended on yet another traffic-filled commute to work.

Yes, turbocharging a Chevy economy car to produce V-8-level horsepower sure fits my definitions of "GM," "high-tech," and "performance," but I know some may not agree-those amongst you are free to skip to the next story. But before doing so, let me bestow upon the closed-minded this wish: enjoy the door dings, paint scratches, and other daily wear and tear on your irreplaceable Z28. I've got 'em all on my Cobalt and, blissfully, I could care less.

A quick refresher for those still following along: the kit we're installing is Hahn's "Stage 2" system (Part No. H TS-2910, MSRP $4,199) designed for 2006 and later manual- and automatic-equipped Cobalts and Pontiac G5s with the 2.4L VVT engine. When we left off last time, the kit installation had progressed to the point where Hahn Racecraft employee Aaron Gilberg had the turbo tightened in place behind this 'Balt's LE5 Ecotec.

This month, we'll finish off most of the exhaust portion of the system and then move to the intake components. Don't miss the September issue for our third and final part of this series, including the remainder of the installation, dyno, track testing, and driving impressions!
