Buy This Porsche Cayman GT4 With a 4.5-Liter DeMan Engine and Embarrass Supercars at the Track

The Cayman GT4 is already pretty cool, but there’s a monster lurking somewhere in the middle of this car.

Matt Farah – noted cat enthusiast and host of The Smoking Tire – recently took delivery of a seriously bananas Porsche Boxster Spyder. Now, a Boxster Spyder is already pretty cool, being the most hardcore version of Porsche’s mid-engine drop-top that you can get, but Matt went ahead and did something most of us would never imagine: He had a shop rip out the zero-mile motor and rebuild it into a monster.

That engine is known as the DeMan 4.5, and while it starts with Porsche’s already-great 4.0-liter naturally aspirated flat-six, the end result would make a GT3 soil itself in fear. That’s because the DeMan 4.5 is good for a whopping 565 hp and, more importantly, 439 lb-ft of torque. And while it’s pretty doubtful that Matt will sell you his Boxster, I’m happy to say that if you’ve got the cashish, there’s another way.

Enter this For Sale ad on the noted Porsche enthusiast forum Rennlist for a 2020 Cayman GT4 with the same drivetrain setup as Matt’s car. Being a GT4, it’s even more desirable to hardcore track rats thanks to its GT3-derived suspension and the added rigidity of a fixed roof. The catch is that if you want it, you’ll have to fork over around $200,000 or around twice the going rate for a standard, low-mileage GT4.
