Garrett's new SFI 61.1 Drag Race Spec Turbos are supported by a certified conversion program that lets racers upgrade their current turbos to meet newly formulated  SFI specs.

Based on the Garrett GT55R and GTX55R turbochargers, the new SFI 61.1 Spec turbos meet all requirements for the NHRA Pro Modified Class as well as those for the American Drag Racing League (ADRL), the Xtreme-Drag Racing League (X-DRL) and
all others requiring the SFI 61.1 spec.

The stainless steel v-band inlet housings offer a 10-pound weight savings over the bolted inlets while the smaller A/R bolted inlet housings carry on the traditional turbine inlet design.

  • The turbocharger must be packaged in such a way to protect it during shipment. Garrett is not responsible for hardware damaged in transit. It is recommended to insure the package.
  • To convert to an SFI 61.1 certified turbocharger or re-certify will take 10 business days pending the turbocharger passes the initial inspection. The cost will be $200/turbo, which includes the initial inspection, assembly, SFI labels/markings, SFI card and ground shipping. The cost of the SFI certified housing will be additional and vary based on the housing selected. If the turbocharger fails the initial inspection and needs repaired, additional cost may be incurred. Further information will be given to you for housing pricing through email.
