How a Maserati V8 Transformed a Porsche 911

In the world of sportscar ownership you get Porsche folks and Ferrari folks. For unknown reasons the two don’t really seem to mix. But what if you are a fan of both brands? Then you build a Porrari. Jimmy Oakes has built a 1978 Porsche 911 SC that now carries a Ferrari-built Maserati V8 where the flat-six used to live.

The build lands in that sweet spot between ridiculous and brilliant. It mixes Porsche chassis work, Maserati hardware, BMW intake parts, Japanese wheels, and a level of fabrication that only makes sense once you see how many systems had to be remade from scratch.

Old Girl

Oakes did not start with a clean shell and a loud idea. The 48-year-old 911 SC needed a full strip-down and restoration before the swap could even begin. The car was taken back to basics, the original rear suspension setup was removed.

The shell was then braced and converted for a very different kind of load. The torsion bars were replaced by coilovers. A full roll cage was also fitted, which was less about showmanship than keeping the shell firm once the powertrain and tyre package grew some muscle.

The narrow body also got pushed out to proper visual and mechanical purpose. Metal fender extensions were welded in at all four corners to create a widebody conversion. The roof was replaced with a carbon fibre skin before the body was repainted in the shade you see now. The finished car wears Porsche Guards Red over Rays wheels.

The Maser-built V8

The heart of Porrari is a naturally aspirated Ferrari-built Maserati F136 V8 taken from a 2007 Maserati Quattroporte. In this form it makes about 300 kW and spins to 8 000 r/min, a long way from the air-cooled 3,0-litre boxer that originally sat behind the rear axle of the 911 SC.

The swap created a problem. The Maserati V8 had no direct relationship with a Porsche transmission, so a custom bellhousing was fabricated to connect the two. The engine bay also needed to breathe properly. Custom headers and exhaust system were made use stainless steel, packaging the V8 into the tight rear of the 911 while keeping the exhaust side of the project from becoming an afterthought.

The intake side went even further off script. Individual throttle bodies from the BMW M3 S65 V8 handle intake duties. The result should sharpen throttle response and turn the F136’s induction note into the sort of sound that gets people looking up before they know why.

Water Cooling

The 911 SC started life as an air-cooled car. That alone makes the Porrari project more involved than a normal swap. A liquid-cooled V8 needs a radiator, coolant routing, and proper thermal management, so the front tub was cut to make room for a radiator and fan assembly.

Once the front end became a cooling package, the original fuel tank had to go. In its place sits a 50-litre fuel cell positioned behind the radiator. New water, fuel, and electrical lines had to run the length of the car. The team built a removable centre tunnel to route everything cleanly and leave the system accessible later.

The swap also forced a rethink of the car’s stopping and turning hardware. Porsche Boxster four-piston Brembo calipers now sit at each corner, matched with EBC rotors. The torsion-bar rear end was replaced with the coilover setup, and the wider track and tyre package give the car the stance to use the extra output instead of simply surviving it.

The finished recipe is deliberately messy in the best way. Porsche structure, Maserati V8, BMW intake parts, Japanese wheels, American fabrication, and German braking hardware all live in one shell.
