Billet Performance Products CNC machined turbo flanges give fabricators and engine builders a clean billet starting point for custom turbo manifold and hot-side work. They are made for builds where flange accuracy matters, whether you are fabricating from scratch, repairing an existing manifold or stepping up to a new turbo frame size. In the workshop, a well-machined flange makes the job easier before the first weld is even laid down. This listing covers the flange patterns shown in the product options, including T25, T3, T4 and T6 layouts in the relevant single or dual entry configurations. FEATURES Material: Premium T6 aluminium Manufacturing: Precision CNC machined Available patterns: T25, T3, T4 and T6 Entry styles: Single and dual entry options depending on flange pattern Use case: Turbo manifold fabrication, repairs and custom hot-side projects Manufacture: Made in Australia TYPICAL APPLICATIONS Custom turbo manifold fabrication Turbocharger frame-size changes on performance builds Workshop repair or modification of existing manifolds Street, drift, drag and circuit turbo projects FITMENT NOTES Select the exact flange size and entry style from the options on this product Always confirm turbo flange pattern, bolt spacing and runner design before ordering Aluminium flanges suit applications designed around this material and should be matched to the intended fabrication method This listing includes multiple variants, so the image and option selected should match your required flange pattern
