Hooker BlackHeart Turbocharger Manifold

Hooker BlackHeart Turbocharger Manifolds: Purpose-Built for LS & LT Swap Turbo Builds

When it comes to building a custom turbocharged engine swap, the turbocharger manifold is one of the most critical—and often most overlooked—components in the system. Hooker BlackHeart approaches this challenge with decades of exhaust engineering heritage behind every casting, delivering turbocharger manifolds that are purpose-designed for serious GM LS and LT swap applications.

High-Silicon-Moly Ductile Iron Construction

What separates Hooker BlackHeart turbo manifolds from the competition starts with the material. High-Silicon-Moly ductile iron is the backbone of these manifolds — a material choice that pays real dividends under boost. Unlike fabricated tube headers, which can warp or crack under the sustained heat cycles of forced induction, cast ductile iron withstands extreme thermal stress and keeps its shape over the long haul. Critically, this material also retains more heat than fabricated alternatives, which directly aids turbocharger efficiency by keeping exhaust gases energetic and moving fast into the turbine housing.

Two Core Product Lines: LS and LT Gen V

Hooker BlackHeart offers turbo manifold solutions for both of GM’s most popular modern performance engine families:

• GM LS Turbo Exhaust Manifolds (e.g., 8510HKR series) — Designed for Gen III/IV LS-based engines (4.8, 5.3, 6.0, and more), these manifolds feature a 3.0-inch V-band turbo outlet and a 2.25-inch V-band crossover connection. Available in natural cast or black ceramic finish, they clear Hooker’s own engine mounts and integrate seamlessly with the wider LS swap ecosystem.
• GM LT Gen V Turbo Exhaust Manifolds (e.g., 8540HKR series) — Built for the modern Gen V LT engine family, these manifolds step up to a 3.0-inch V-band turbo outlet and 2.5-inch V-band crossover connections, providing a tight, leak-free seal. Their compact form factor delivers better fitment across multiple chassis and improves spark plug access versus many fabricated headers.

Designed as Part of a Complete Swap System

One of Hooker BlackHeart’s most compelling strengths in this category is ecosystem integration. These turbo manifolds are not standalone products — they are engineered as the building blocks of a complete custom turbo system, designed to work alongside Hooker’s motor mounts, swap oil pans, and accessory drive systems. A turbo cross-over tube is available for manifold connection, and a universal cross-over component kit exists for fully custom fabrication applications. This holistic approach means builders spend less time sorting clearance issues and more time making power.

V-Band Connections and Stainless Hardware

Both LS and LT manifold kits use V-band clamp connections rather than conventional flanges. V-band joints are the preferred choice in turbocharged applications because they seal reliably, resist leaks under thermal cycling, and make turbo positioning and removal straightforward. Kits include stainless steel V-band clamps, flanges, and header bolts where applicable — hardware that is up to the job in a high-heat, high-vibration turbo environment.

A Legacy That Backs Every Manifold

Hooker BlackHeart is the premium performance line from Hooker Headers, a brand that has been innovating in the exhaust space since 1962. That motorsports-forged DNA — balancing intake and exhaust pressure waves to create real, usable power — carries directly into how these turbo manifolds are engineered. For builders looking to combine proven swap hardware with a cast manifold that can handle the demands of forced induction, Hooker BlackHeart is a logical first stop.
