STS Turbo expands its Rear Mount Turbo Systems with a new offering for the popular LS3 powered 2010-2013 Chevrolet Corvette C6 Grand Sport. These patented rear mounted twin turbo systems offer excellent horsepower and torque gains. STS Turbo systems overcome challenges of traditional installations by mounting the turbos in the rear of the vehicle. This allows you to retain stock exhaust manifolds, catalytic converters, and mid pipes. The stock intake and throttle body are also able to be retained if desired. Relocating the turbos to the rear helps avoid adding additional heat under your hood and you won't have to worry about clearance or interference issues with the belts, pulleys, or accessories in the engine bay. You'll also get a better weight transfer since the turbos are in the rear and are not adding additional weight to the front of your vehicle. These systems are available as a Tuning Kit which includes STS Turbo specific DiabloSport inTune i3 handheld tuner along with higher rate fuel injectors or as a Standard Kit without these items so you can choose your own custom tuning and fuel injectors. STS Rear Mount Turbo Systems come complete with all the components needed for an OEM quality installation, right down to every nut and bolt along with a full color installation manual to walk you through the installation.
