The Sinister Diesel Powermax Series 2 Turbo uses a larger compressor wheel to deliver quick turbo spool, mid and top-end horsepower, and crisp throttle response in convenient bolt-on package. The Series 2 Turbo specifically includes a Billet BatMoWheel compressor wheel by Bullseye Performance. The lighter compressor wheel mass significantly improves spool-up time for the Turbo. In addition, this turbo features Garrett Advanced Variable Nozzle Turbine design that allows for increased compressor flow and boost response. This unit is built by the original manufacturer using original-style housings so they are 100% compatible with your Ford truck's Powerstroke engine for a drop in installation. The turbo's compressor cover comes finished in our high gloss signature "Sinister Blue"
