    Details

    Holley's new LT Turbo Exhaust Manifolds provide a simple and effective way to add a turbo to your LT powered car or truck. These turbo manifolds are made from High-Silicon-Moly ductile iron, which are much more durable and retain more heat than fabricated headers. This added heat retention aids in turbo efficiency. Their compact design allows for better fitment in multiple applications and better spark plug access than many fabricated headers do. These manifolds work with most common LT swap parts (i.e. motor mounts, swap oil pan, and accessory drive systems) & provide the basic building blocks needed to complete a custom turbo system for your GM LT engine.

    Features:

    • Designed to integrate with the most common LT swap applications and components
    • 3 inch V-Band outlet and 2.5 inch V-Band crossover connections provide a tight seal
    • Includes a heat shield to protect heater hoses
    • Hardware included - Stainless steel V-Band clamps, V-Band flanges and header bolts
    • High-Silicon-Moly Ductile iron construction retains heat for better turbo efficiency and is more durable that headers
    • Compact design allows for better fitment and spark plug access
