Refined Horsepower best describes the supercharged 6.2L LSA engine that is standard in the Cadillac CTS-V and the ZL1 Camaro! It is smooth, quiet, and well-balanced — all the while delivering breathtaking power when you need it. The baby brother to the monster LS9 used in the ZR1 Corvette, the LSA may be the best value, on a dollar-to-horsepower basis in the Chevrolet Performance LS-based portfolio.
Although it has the same displacement as our 6.2L LS3, the LSA has a unique, extra-strength cylinder block to accommodate the extra horsepower generated by the supercharger. The LSA uses a forged steel crankshaft, along with piston-cooling oil jets and high-flow cylinder heads under its inter-cooled supercharger to produce 556 hp at 6100 rpm and a whopping 551 lb/ft of torque at 3800 rpm. The compact design 1.9L supercharger incorporates an integrated water fed inter-cooler to assist the four-lobe, high-twist rotors in packing the rectangular port aluminum heads with a denser air/fuel charge. The LSA has a conventional wet sump lubrication system.
Chevrolet Performance’s lightweight all-aluminum LSA 6.2L supercharged engine package comes complete from supercharger to oil pan, including water pump and individual coil ignition system.
