Performance & Application
The GTW3884R is Garrett’s Performance solution to the popular 6766 size turbo, offering great performance at a competitive price. Its ball bearing design and 950HP potential flow make it well suited for high-output builds seeking strong power delivery. The turbine housing mounts directly to existing TiAL flanged turbo manifolds and down-pipes, making it an ideal upgrade path for platforms already built around that V-band standard. For builders wanting a different turbine housing characteristic, a 1.03 A/R V-Band Turbine Housing option is also available in place of the standard .82 A/R.
Compatibility & Fitment
- Turbine housing is compatible with and mounts to existing TiAL flanged turbo manifolds
- Turbine housing is compatible with and mounts to existing TiAL flanged down-pipes
