After 2 years in production, Speed Engineering is finally proud to announce the release of their twin turbo systems for the Silverado and Sierra platforms. Their goal with these kits was to make the most complete, best fitting, most versatile turbo system on the market at an affordable price. Most turbo kits on the market today are either extremely expensive or really cheap, essentially getting what you pay for. Speed Engineering's turbo systems focus on just that, a quality well-built kit without the price tag of a one-off turbo system. Their systems utilize Turbonetics 64mm TNX turbos, Air-To-Air intercooler and your choice of an exhaust connection type.
Speed Engineering's kit has been tested on several applications. The first application was a 6.0L LQ4 stock engine with a 224 camshaft. On their Mustang 1100MD dyno it made 495rwhp on 5lbs of boost. Their second application was a 4.8L, which was also a stock engine minus a 224 cam swap. It made 710rwhp on 18lbs. Their third application was a built 6.0L with heads/cam. It went on to make 750rwhp on 15lbs, and 800rwhp on 18lbs.
One of the nice features with the sizing of this kit is the ability to run a stock displacement engine with quick spool time. At the same time, you have a ton of potential to crank the kit up if desired. If you choose to purchase one of these kits, we can promise you will not find a better fitting, quality built, budget turbo system for your vehicle.
