Dinan Supplemental Big Turbo Hardware Kit

The Dinan Supplemental Big Turbo Hardware Kit supplies all the additional gaskets, seals, and mounting hardware required to complete a Dinan big turbocharger installation when full turbo manifold removal is necessary. On select vehicle configurations, the turbo manifold must be physically removed during a Dinan big turbo upgrade — a more involved process than the simplified cassette-swap method available on other applications. When the manifold is disturbed, existing gaskets and hardware become non-reusable per BMW-recommended procedure. This supplemental kit provides every replacement component needed to restore a factory-quality seal and achieve proper, leak-free fitment.

Why This Kit Is Required:

Certain drivetrain configurations prevent the simplified cassette-swap installation method, requiring the turbo manifold to be fully removed. Unlike installations where the new turbo cassette can be swapped without disturbing the manifold or its sealing surfaces, this more involved process requires all affected sealing surfaces to be refreshed. This kit addresses that specific requirement, providing the correct replacement components to complete the installation properly and to Dinan's exacting standards.

Kit Highlights:

• Complete gasket and seal coverage for every sealing surface disturbed during full turbo manifold removal
• Supplemental mounting hardware required for proper turbocharger fitment following manifold removal
• OEM-quality components selected and validated to Dinan's precision forced induction engineering standards
• Multiple variants available — each configuration engineered for a specific engine and drivetrain application
