RB26 Cylinder Head - 3D Scan

RB26 Cylinder Head - 3D Scan

Manifolds seal or leak at the port face. Design yours on the real RB26 head, not a flange template.

This is a full 3D scan of the OEM Nissan RB26 cylinder head, delivered as an STL for your CAD or reverse-engineering software. Use it to design exhaust manifolds, intake plenums, ITB adapters, cam covers and anything else that bolts to the head.

The port positions, flange faces and stud locations are what a manifold has to hit. The scan gives you all of them from one casting, so the flange you cut lines up with the head it's going on.

Scanned in-house by Ichiban Engineering, a CNC shop in Bangkok. Volumetric accuracy is 0.1 mm.

This is a raw scan mesh. It's not watertight and not a solid CAD model, so model over it rather than machining from it. Inside the casting, the port runners are only partly captured and the water jackets aren't captured at all, so use it for flanges and covers, not port work.

Key Features

• Real port faces - Intake and exhaust flanges with their stud positions, captured from the outside.

• 0.1 mm volumetric accuracy - Tight enough to lay out flanges and covers.

• Bare casting - No cams or valvetrain in the way.

• STL mesh - Opens in Geomagic Design X, Fusion, SolidWorks and most scan software.

• Instant download - The file link arrives right after checkout.

Your manifold is only as good as the flange it starts from.
