BMW/Supra B58 6 Port Single Turbo Hot Part Kit

Upgrade your B58 platform to a true high-performance setup with the BMW / Supra B58 6-Port Single Turbo Hot Part Kit—engineered for serious power gains, improved exhaust flow, and uncompromising durability. Designed specifically for the modern turbocharged inline-6 found in models like the BMW M240i, M340i, and Toyota Supra A90/A91, this kit provides the essential “hot side” components required to convert your factory twin-scroll turbo system into a high-efficiency single turbo configuration. Product Overview The B58 6-Port Single Turbo Hot Part Kit is a complete exhaust-side solution built to handle extreme heat, pressure, and high horsepower applications. By replacing the restrictive OEM manifold and turbo housing with a precision-engineered tubular setup, this kit maximizes exhaust gas velocity and flow, allowing your turbocharger to spool faster and operate more efficiently at higher boost levels. This system is ideal for enthusiasts looking to push beyond the limits of stock or hybrid turbo setups and achieve consistent, reliable power in the 600–1000+ horsepower range (depending on turbo selection and supporting modifications). Key Features 6-Port Equal Flow Turbo Manifold Design Engineered with a true 6-port configuration, this manifold ensures each cylinder has a dedicated exhaust runner. This improves exhaust pulse energy, reduces turbulence, and enhances turbo spool characteristics compared to merged or log-style manifolds. High-Grade Stainless Steel Construction Manufactured from premium T304 stainless steel, the manifold and hot side components are built to withstand extreme exhaust temperatures and resist cracking under high boost conditions. Precision TIG welding ensures long-term durability and structural integrity. Optimized Runner Geometry Each runner is carefully designed for equal length and smooth transitions, promoting balanced airflow and maximizing performance efficiency across the entire RPM range. V-Band Connections for Secure Fitment Equipped with high-quality V-band clamps and flanges, the system ensures a tight, leak-free seal while allowing for easier installation and removal compared to traditional bolt-on flanges. External Wastegate Compatibility Designed to support external wastegates (commonly 44mm or 45mm), providing superior boost control and preventing boost creep in high-performance applications. Modular Turbo Compatibility Compatible with a wide range of single turbochargers, allowing you to customize your build based on power goals—whether you're aiming for quick spool street performance or maximum top-end power.

Custom tuning, fueling upgrades, and supporting modifications are required for optimal performance. Why Upgrade to a Single Turbo Hot Part Kit? The factory B58 turbo system is efficient but limited when pushing for extreme horsepower. A single turbo conversion unlocks the full potential of the engine by improving airflow dynamics and allowing for larger turbocharger options. This 6-port hot part kit is the backbone of that transformation—delivering the strength, flow, and reliability needed for serious builds. Take Your B58 to the Next Level Whether you're building a high-horsepower street car or a dedicated track machine, the BMW / Supra B58 6-Port Single Turbo Hot Part Kit delivers the performance foundation you need. Pair it with the right turbocharger and supporting mods, and experience a new level of power, sound, and driving excitement.
