2016+ CTS-V3 (LT4) Engine

2016+ CTS-V3 (LT4) Engine

The SIDI LT motors like the LT4 found in the 2016+ CTS V is the most revolutionary masterpiece released from GM in nearly 20 years.  It's Direct Injection OHV V8 design is a first in the industry and GM stayed true with a big displacement still and tackled the government regulations with AFM and VVT opposed to decreasing the cubic inches.  Also, as you've probably seen, it responds extremely well to modification!  A motor is nothing more than an air moving machine.  Less restriction and more air ingestion results in more HP!  Looking to beef up your current bottom end or build a complete short block, find it here.
