Speed Engineering's 99-06 Silverado & Sierra twin turbo kit is a great, affordable option for your 4.8, 5.3, or 6.0l. Their turbo systems focus on a quality, well-built, affordable option that can be installed without a large amount of modifying/customization. This system uses twin Precision 6262 T3 .85ar turbochargers standard (can be upgraded if desired - email us for options), an air-to-air intercooler, and a Speed Engineering X-pipe kit (which will connect to their dual exhaust systems).
