RB26 Bare Block - 3D Scan

RB26 Bare Block - 3D Scan

An RB26 swap lives or dies on what bolts to the block. Design the mounts, sump and brackets on the real thing.

This is a full 3D scan of the bare OEM Nissan RB26 standard engine block, delivered as an STL for your CAD or reverse-engineering software. Use it to lay out engine mounts, sumps, accessory brackets and anything else that has to bolt to or clear the block.

A block is too big and too complex to measure with calipers and a tape. The scan gives you the casting, the bolt bosses and the bore positions in one file, so the bracket you design is the bracket that fits.

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. The water jacket passages inside the casting aren't captured.

Key Features

• Full exterior - Deck, sump rail, both sides, front and rear faces, plus the bores.

• 0.1 mm volumetric accuracy - Mounting points located from the real casting.

• Bare block - No crank, pistons or covers in the way of the surfaces you need.

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

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

Fifty bucks is cheaper than a second set of mounts.
