The Garrett GTW3884R is a purpose-built 62mm ball bearing turbocharger for enthusiasts who want big power without sacrificing the drivability of a properly matched, high-flowing compressor and turbine combination. Engineered as Garrett’s performance-focused alternative to the popular 6266 turbo size, it delivers serious top-end capability while keeping cost in check. This is the turbo for builders who demand real flow numbers backed by Garrett engineering, not marketing hype.

Performance & Application
The GTW3884R is built for high-horsepower applications where a strong, efficient compressor side needs to be paired with a turbine housing capable of feeding it under real boost demand. Its .82 A/R stainless steel V-Band turbine housing is designed to bolt directly onto existing TiAL flanged turbo manifolds and down-pipes, simplifying installation for builders already running TiAL V-Band hardware. The T04S compressor housing’s built-in and machined anti-surge design supports strong, stable airflow delivery at the high boost levels this turbo is capable of producing. This combination makes the GTW3884R a strong choice for serious performance builds looking to push into the 800HP flow potential range.
Compatibility & Fitment
- Turbine housing is compatible and mounts to existing TiAL flanged turbo manifolds
- Turbine housing is compatible and mounts to existing TiAL flanged down-pipes
