From the crankcase to the bevel-shaft drive. Explore our components and discuss the right specification with us.
Porsche 4-Cam parts catalogue
01The foundation of the engine. Reproduced cases for demanding four-cam projects.
02Start with the engine type and cylinder bank. We agree the fitted components and machining requirements with you.
03The crankshaft is reviewed alongside stroke, crankcase, bearings and connecting rods as part of the rotating assembly.
04Components for the distinctive drive of the four overhead camshafts.
05Connecting the induction system to the cylinder head, matched to the agreed configuration.
06Engine type, fan configuration and existing components help identify the appropriate fan stand.
Find further components and our own part numbers in the catalogue. Suitability for your engine type, scope of supply and lead time are confirmed individually.
Explore spare partsFOR REPLICA BUILDS
Newly manufactured four-cam engines and components for your replica project. For manufacturers, workshops and private builders.
We review the engine specification against your chassis, transmission and installation space together.

02 / ENGINEERING
A rare component is no longer available? We assess reproduction from a sample, drawing or CAD data for historic vehicles, machinery and other technical applications. Function, quantity and manufacturing route are agreed with you.
Explore part reproduction and the processINSIDE OUR CYLINDER HEAD DEVELOPMENT
Surviving components and records provide the starting point.
Existing references are developed into an engineered model.
Casting and machining turn the design into a component.
03 / ENGINEERING WITH A PERSONAL COMMITMENT
André Mössner reconstructed the four-cam engine step by step, working from surviving components, scans and drawings. From the cylinder heads to the crankcase, each part and its relationship with the others had to be worked out anew.
His work also includes designing the casting moulds. André follows the process into the foundry and takes an active part in casting the components. This detailed work created the basis for manufacturing a complete engine anew.
The first cylinder head is scanned and reconstructed.
Retro-Design 3D GmbH is founded in Mössingen.
The first bevel-drive shafts are manufactured.
The first complete four-cam engine is finished.
Ten years of Retro-Design 3D. Reproduction enquiries for other vehicles and machinery are assessed individually for feasibility.
We work with engine builders, restoration workshops and private owners. Replica manufacturers and builders can also discuss their project directly with us.

Cylinder head · Retro-Design 3D
voxeljet documented Retro-Design 3D’s reconstruction of a Carrera cylinder head in Mössingen. The CAD data provided the basis for 3D-printed sand cores and the subsequent aluminium casting.
