3 Stage Mechanical Actuator VGT

  • Improves spool-up by 200-300 RPM's

Electronic VGT with Exhaust Brake

  • Improves spool-up by 200-300 RPM's
  • Improves turbo performance and output
  • Adds Exhaust Brake to Turbo
  • Exhaust Braking Function with the Turbonator® VGT - will always increase exhaust pressure while braking, however, Diesel Power Source does NOT guarantee a specific Exhaust Braking force as every truck and application will be different. We mainly recommend the exhaust brake (hybrid) option for trucks built in 2003 or after.

If using our turbo in compounds on the first-gen Cummins, please let us know so we can configure the wastegate with a spring gate to prevent damage to your 1 gen Cummins.

**PLEASE NOTE: IF ORDERING FOR FOR COMPOUNDS, PLEASE LET US KNOW, WE MUST CHANGE THE WASTEGATE TO A SPRING GATE SO THE ADDITIONAL PRESSURE DOESN'T DAMAGE THE WASTEGATE BY OPENING IT TOO FAR**
