Turbosmart TS-19TH75C-T4124 C-Frame Turbine Housing T4 1.24AR 75mm Exducer TS-1

Vehicle Fitment

• Universal - compatible with Turbosmart C-Frame TS-1 and TS-2 turbochargers featuring a 75mm turbine exducer, requiring a standard single-entry T4 inlet turbine housing at 1.24 A/R

Fitment Notes

• Suits C-Frame Turbosmart TS-1 and TS-2 turbochargers with a 75mm turbine exducer only - not compatible with 70mm exducer variants (those use the TS-19TH70C series)
• Single-entry T4 inlet - requires a standard merged T4 exhaust manifold flange; not interchangeable with T4 Divided (twin-scroll) manifolds (for divided inlet, use TS-19TH75C-D4115)
• Does not suit Reverse Rotation turbocharger models
• 1.24 A/R - larger than the T4 Divided 1.15 A/R variant (TS-19TH75C-D4115); best suited to high-displacement or high-RPM builds where peak power is the priority over minimum spool speed
• Race and competition use only; not CARB legal and not for use on pollution-controlled road vehicles

Features

• 310s stainless steel investment cast construction for exceptional high-temperature strength, thermal stability, and impact resistance throughout the turbocharger's service life
• CFD-driven design optimizes aerodynamic flow through the housing at the specified 1.24 A/R for maximum efficiency and minimal backpressure
• Single-entry T4 inlet suits standard merged exhaust manifolds - the most widely available T4 manifold configuration across aftermarket and custom fabrication
• V-band turbine outlet for a secure, leak-free downpipe connection with easy removal for service
• Turbosmart genuine spare - the same component used in factory TS-1 and TS-2 turbocharger assembly, available for upgrade, service, or rebuild

Product Description

The Turbosmart TS-19TH75C-T4124 is a genuine replacement turbine housing for C-Frame Turbosmart TS-1 and TS-2 turbochargers equipped with a 75mm turbine exducer. Unlike the TS-19TH75C-D4115 which uses a T4 Divided twin-scroll inlet, this housing features a standard single-entry T4 inlet flange, making it compatible with the far wider range of conventional merged T4 exhaust manifolds available in both aftermarket and custom fabrication. At 1.24 A/R - the largest available in the 75mm C-Frame T4 series - it is positioned for high-displacement and high-RPM applications where maximum top-end power output is the goal and a broader power band is acceptable over the quickest possible spool.

Cast from 310s stainless steel with CFD-optimized internal aerodynamics, this is the same housing Turbosmart uses in TS-1 and TS-2 factory assembly - making it equally suited for direct housing replacement, A/R upgrade from a smaller variant, or a complete turbocharger rebuild. The V-band turbine outlet ensures a clean, serviceable downpipe connection. Builders using divided twin-scroll manifolds should use TS-19TH75C-D4115 (T4 Divided, 1.15 A/R) instead, as the single-entry and divided T4 inlet flanges are not interchangeable.
