Speed Engineering Twin Turbo Kit for 1999-06 Chevy Silverado/GMC Sierra 32-TwinKit-9906

Speed Engineering is proud to announce the release of twin turbo systems for the Silverado and Sierra platforms. Speed Engineering's 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 turbo systems focus on just that a quality well-built kit, without the price tag of a one off turbo system. Speed Engineering systems utilize 64mm Precision Turbochargers with 55mm Turbines, Air-To-Air intercooler, and your choice of an exhaust connection type.

This kit has been tested on several applications. The first application was a 6.0L LQ4 stock engine with a 224 camshaft. On the Mustang 1100MD dyno it made 495rwhp on 5lbs of boost. The second application was a 4.8L, which was also a stock engine minus a 224 cam swap. It made 710rwhp on 18lbs. The 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 the kit is the ability to run a stock displacement engine with quick spool time. At the same time have a ton of potential to crank the kit up if desired. If you choose to purchase one of The kits we can promise you will not find a better fitting, quality built, budget turbo system for your vehicle.
