Free Shipping!

The 2009-13 Cadillac CTS-V LSA supercharged engine produces 556 HP and 551 ft/lbs of torque. Enough power to propel the CTS-V from 0 to 60 in 3.9 seconds and a Cadillac record of 7:59:32 around the Nurburging, making the CTS-V the fastest production sedan in the world and capable of 191 mph top speed when using the manual transmission. In all, the LSA offers a tremendously powerful supercharged engine package with the sophistication necessary to be Cadillac.

Chevrolet Performance is proud to offer this fully dressed production engine. While it shares the 6.2L displacement of other LS engines, this engine is built with powdered metal rods, forged crankshaft, and 9.1 comp ratio. The supercharger has a single brick intercooler in the intake with a very low profile to optimize clearance. This engine package has a broad torque curve with serious power on tap for your high-performance needs!
