Garrett GTX3076R Gen1 Dual Ball Bearing Turbo – less turbine housing

The Garrett GTX3076R Gen1 Dual Ball Bearing Turbo is built for serious performance enthusiasts who demand faster spool and higher-flow capability than a traditional GT30R while retaining a familiar footprint. Sold less turbine housing, this configuration gives builders the flexibility to pair the ultra-high-flow GTX compressor wheel with the turbine housing that best matches their application. It’s the choice for those upgrading from a GT3076R or GT30R platform who want more top-end without sacrificing the bolt-up simplicity of the GT30R family.

Performance & Application

This GTX3076R Gen1 is engineered for builders stepping up from a stock or GT3076R-based setup who want a meaningful jump in compressor flow while keeping the same overall turbo architecture. The dual ball bearing center cartridge sharpens throttle response and shortens spool time compared to journal bearing counterparts, while the ultra-high-flow compressor wheel extends the usable power band further into the top end. Because it shares oiling, cooling, and turbine housing compatibility with the established GT30R/GT35R family, it drops into existing setups with minimal supporting hardware changes. This is a strong option for enthusiasts targeting more power without a full system overhaul.

Frequently Asked Questions

Does this turbo come with a turbine housing?

No, the turbine housing is sold separately. It uses the same turbine housing as the GT30R with a 60mm turbine wheel.

Is the GTX3076R Gen1 a ball bearing or journal bearing turbo?

It is a dual ball bearing turbo.

What is the stock compressor housing configuration?

The stock compressor housing is a T04E frame, the same frame used on the GT3076R, with a 4″ inlet and 2″ outlet.

Will this turbo use the same oil and coolant fittings as my GT30R or GT35R?

Yes, this GTX model uses all the same oil and coolant fittings as the standard GT30R/GT35R turbo.

For enthusiasts who want the proven GT30R footprint with the added flow capacity of Garrett’s GTX compressor technology, the GTX3076R Gen1 Dual Ball Bearing Turbo delivers a direct, well-documented upgrade path backed by genuine Garrett part numbers.
