Say goodbye to the problematic and small GT32 Single Sequential Turbocharger (SST) on the early model Ford 6.7L Powerstrokes by replacing it with BD's complete Screamer Stage 1 Retrofit Turbo solution. Utilizing modern turbo technology, the Screamer Stage 1 delivers up to 66lb/min of increased airflow without compromising on low end response and everything you require is included to drop right in place of the old unit, no extra pieces needed. The Screamer Stage 1 Retrofit turbo will require tuner such as the Edge Insight to ensure no faults codes are set. For trucks wanting to push past 500hp, we recommend the Screamer Stage 2 Retrofit kit (1045825).
