Click above for a gallery of the Synapse Turbo Chevrolet Cobalt SS

Within 20 minutes of taking delivery of a Pontiac Solstice GXP last year, we were on our way to our local shop to see what mods could be done to the turbocharged 2.0-liter four-pot. With 260 hp and a claimed 260 lb-ft of torque (our dyno run showed around 250 lb-ft of twist at the wheels), the Solstice is hardly lacking for grunt, and when we finally got around to driving the Chevrolet Cobalt SS, we were sure that the new engine would be embraced by power-hungry tuners in short order.

Scotia, NY-based Synapse Turbo has taken up the task and created a bolt-on kit for the Cobalt SS that puts out 371 hp and 383 lb-ft of torque. From what we can gather based on forum postings and the video after the jump, the Stage 3 kit consists of a Garrett GT2871R turbo, stainless steel 4-1 exhaust manifold, three-inch downpipe, three-inch intake, TurboXS BOV, a new intercooler and aluminum plumbing. ECU tweaks were provided by the HP Tuner system and redline has been raised to 6,700 rpm. We're itching to get some time behind the wheel, if for no other reason than to see if our wrists can cope with the torque steer, but until then, the video below the fold will have to do.
