Porsche 911s at SEMA Swap Flat-Sixes for V8 Engines

At the 2026 SEMA Show, held from November 3 to November 6 at the Las Vegas Convention Center, two iconic Porsche 911 models underwent significant transformations. Reportedly, one of these cars, a 1978 model, was fitted with a Ferrari-built Maserati V8 engine, earning it the nickname 'Porrari.' Meanwhile, a 2007 Porsche 911 received a GM LS2 small-block V8 engine, replacing its previous Subaru STI flat-four powerplant.

The 1978 Porsche 911 required additional modifications to accommodate the new V8 engine, including a custom bellhousing, clutch, and flywheel. This car, along with its 2007 counterpart, featured a range of upgrades such as enhanced brakes, coilover suspension, and widebody conversions. These modifications not only changed the look of the vehicles but also significantly altered their performance characteristics.

Both Porsches showcased at the 2026 SEMA Show represented a unique blend of classic design and modern engineering, attracting considerable attention from enthusiasts and industry experts alike. The swap of engines from the traditional flat-six configuration to V8s highlighted the versatility and adaptability of these beloved sports cars, demonstrating how they can be reimagined with different powertrains while maintaining their distinctive identity.
