Carrera Intake Manifold Adapter Set

TurboKraft Carrera Manifold Adapter Sets are designed for simply adap the 911 Carrera 3.2L intake manifold to the 930 Turbo engine.  With an intake runner port size of 41.5mm, the 911 Carrera manifolds make an excellent choice for high-performance engines requiring additional airflow as part of an EFI conversion. Turbo cylinder head ports are only 32mm inside diameter.  If you attempt to use a factory 3.2 Carrera intake insulator and gaskets, you'll find the I.D. of the gasket protrudes outside of the heads' intake flange, causing a vacuum leak.   TurboKraft's adapter set creates a positive sealing solution for Turbo heads, while providing a smooth airflow transition from 41.5mm down to 32mm.Additionally, our adapters incorporate a stepped mounting surface for proper clearance of the Turbo engine fan shroud.  No more removing the heads for welding and re-machining, or cutting the (discontinued) Turbo fan shroud to clear the Carrera manifold.TurboKraft’s insulator blocks are machined fr
