1.16 A/R T3 DIVIDED Turbine Housing for GTW3684 (GTW6262) welded 3″ GT V-Band Exit

This 1.16 A/R divided T3 turbine housing is engineered specifically for the Garrett GTW3684 platform, giving builders a precise exhaust-side solution for both journal bearing and ball bearing turbo configurations. Designed for enthusiasts who demand optimized exhaust scavenging and sharper turbo response, this housing is built to extract maximum performance from the GTW3684 lineup. It’s the right choice for anyone running a divided exhaust manifold setup who wants a factory-matched, purpose-built housing rather than a compromise fit.

Specifications

• Housing Type: Divided (Twin Scroll / Twin Entry) T3
• A/R Ratio: 1.16
• Turbine Outlet: 3″ GT V-Band Exit (welded to the turbine housing)
• Compatible Turbo Models: GTW3684 (also known as GTW6262)
• Bearing Compatibility: Journal Bearing and Ball Bearing versions

Performance & Application

This divided T3 housing is built for GTW3684/GTW6262 turbocharger applications where exhaust pulse separation is critical to performance. The twin scroll design helps maintain exhaust energy separation between cylinder banks, supporting improved spool characteristics compared to a non-divided housing. It works across both journal bearing and ball bearing versions of the GTW3684, giving builders flexibility depending on which core configuration they’re running. The welded 3″ GT V-Band exit simplifies downpipe integration for serious builds.

Compatibility & Fitment

• Garrett GTW3684 turbocharger (journal bearing version)
• Garrett GTW3684 turbocharger (ball bearing version)
• Also compatible with GTW6262, an alternate designation for the same platform

Frequently Asked Questions

What does “divided” mean for this turbine housing?

Divided refers to a twin scroll (also called twin entry) housing design that separates exhaust pulses from different cylinder banks.

What is the A/R ratio of this housing?

This turbine housing has a 1.16 A/R ratio.

Does this housing work with both journal bearing and ball bearing GTW3684 turbos?

Yes, this housing is compatible with both the journal bearing and ball bearing versions of the GTW3684.

What does GTW6262 refer to?

GTW6262 is an alternate name for the Garrett GTW3684 turbocharger.

For GTW3684/GTW6262 builds requiring true divided exhaust flow, this 1.16 A/R T3 housing with its welded 3″ GT V-Band exit delivers a factory-engineered fit across both bearing configurations.
