The LNF Turbo Upgrade also gives the GXP, Redline and SS the same "no-lift shift" functionality as the Cobalt SS Turbo, which enables you to shift without taking your foot off the accelerator. The kit also bumps the redline by 200 to 6500, but the hulkified 2.0L engine will now demand premium fuel to deliver its increased power delivery. The General is also working on a similar upgrade kit for the Cobalt SS, and it should arrive at your local Chevy dealer during Q1 2009. The LNF turbo kit delivers some added pop to three already fun vehicles, and it can be purchased at a GM dealer for $650. Is it worth the extra coin? It's up to you, but we're guessing it couldn't hurt. You can check out assembly instructions for the LNF Turbo Upgrade kit here.
