Function and Performance
  • A/R Ratio (1.32): This ratio represents a middle-ground "sweet spot" for many truckers. It is small enough to provide quick spool-up and low-end torque but large enough to maintain high-RPM flow without excessive backpressure.
  • Wastegate Integration: Unlike non-gated housings, this version includes an internal valve (gate) that allows exhaust gas to bypass the turbine wheel once a specific boost pressure is reached.
  • Boost Control: The wastegate typically begins to open around 29–34 PSI and reaches full open at approximately 38 PSI. This prevents the turbocharger from exceeding safe RPM limits, which can lead to catastrophic failure.
Key Benefits for Heavy Hauling
  • Lower EGTs: By bleeding off excess exhaust once the desired boost is achieved, the housing helps keep turbo speed from exceeding the reliable RPM limit for shaft speed. This gives the turbo a longer life expectancy than non-gated housings.
  • Improved Spool-Up: The 1.32 A/R size provides a fast throttle response, helping the truck enter its power band much quicker than larger 1.45 or 1.58 housings.
  • Drivability: It allows for larger turbos (like the S400 or S410 series) to be used on smaller engines without sacrificing bottom-end response.

Enhanced Power Products provides the high-performance solutions you need to take control of your rig’s boost and exhaust flow. The 1.32 Waste Gated Exhaust Housing is a specialized part engineered specifically for drivers who demand precision and reliability from their diesel engine turbo parts. By incorporating a wastegated design, this housing allows you to maintain higher boost levels while effectively protecting your engine from over-speeding, ensuring that your power delivery remains consistent even under the heaviest loads.

Finding professional-grade diesel turbo parts online is now simpler than ever. Our 1.32 A/R housing is built to withstand the extreme temperatures and pressures common in heavy-duty applications. This component is essential for those seeking performance diesel turbo parts that bridge the gap between daily street drivability and industrial-strength towing capacity. We ensure every housing is machined to exacting tolerances to provide a perfect fit and a significant, noticeable improvement in your overall throttle response. Order today.


Common Applications & Compatibility
  • Turbo Series: Primarily fits BorgWarner S400, S410, S475, and S480 Series Turbos featuring a 96 turbine wheel.
  • Engine Specs: Ideal for engines in the 600–650 HP range.
  • Interchangeability: Often designed as a direct replacement for standard T6 flange housings, including part numbers like 171701 and 171702
This exhaust housing is waste gated with a short travel actuator. The actuator has a 38 PSI spring to keep turbo shaft RPMs and drive pressure down, which keeps the turbo running in the correct efficiency range. This also includes a 28 PSI spring if you're running it in a twin set up and want to dump the exhaust into the atmosphere charger sooner.

Fits any S400 series turbo with 96x88 turbine wheel.
