Bisimoto’s Water-Cooled 930 From Hell

When it comes to turbocharging cars, and squeezing insane horsepower numbers out of engines, Bisi Ezerioha of Bisimoto is ahead of the curve. In 1994, he founded Bisimoto Engineering, setting out to show the world it doesn’t take a 2JZ or LS to make some serious power.

Whether it’s his 2014 Honda Odyssey minivan making around 1000 hp, or a 1991 Honda Civic wagon making similar power, he’s done it all. But then it comes to Porsches, where Bisi not only focuses on big power, but also beauty. From widebodies to turbofan wheels, and center-seat Boxters to rear bumper deletes with twin turbos exposed, you’re sure to fall in love with each one of his builds. 

There is one particular build that stands out among the rest, which happens to be his Porsche 930. If you happen to classify yourself as a Porsche ‘Purist’, this may be the time to stop reading, but if you are a gearhead who enjoys a beautiful build with some extra power, you’ll definitely want to stick around for this insane 930.

To start, you may need a refresher on what the 930 designation means. Porsche 911 Turbos built between the years 1975 and 1989 received the 930 designation. All of these years also included an air-cooled engine, something enthusiasts have loved about Porsche from the get go. However, the air-cooled Porsche died in 1998 when the 996 was born, an unliked variant of the 911 that came with the first water-cooled engines.

The 996 isn’t necessarily important to this, but Bisi’s 930 did get a heart transplant straight from one. Yes, for any purists still sticking around, you heard that correctly. Bisi swapped out an air-cooled 930 engine for a water-cooled 996 power plant. The 996 engine was actually busted when Bisi got it, but after his special touch with some Bisimoto internals and a matching pair of 57-mm billet turbos, the Bisimoto 911 Frankenstein was ready to make some real power.

Taking a step back, you need to understand that Bisi isn’t just an experienced racer and car builder, but he also has a background as a chemical engineer. An engineer’s brain works a little different than the average joe. You wouldn’t expect Bisi to find a 930, throw in a rebuilt motor, and call it a day. No, Bisi needed to break down the entire car to its bare bones, analyze what needed to be changed, find a way to solve that problem, and then build it back up stronger and more efficient than before. In the end, Bisi would have himself a water-cooled, twin-turbo 930 that is not only incredibly powerful, but efficient in getting that power to the wheels, and reliable.

Focusing back on the Porsche, the 3.4 liter flat-six 996 engine features sequential fuel injection, a 50:50 methanol-water injection system, and a boost control unit allowing the car to hit 850 hp at 18 psi, while settling for lower boost for city cruising. As soon as you’re able to move your attention away from the engine bay and exposed turbos, you’ll notice that the 930 is slightly wider than normal. The fenders were extended out by two inches, a customized GT3 front bumper was attached, and an IROC-homage rear wing was fitted to the rear. The car is lowered on coilovers designed by Bisimoto, giving it that last racecar touch.

The interior of the 930 has somewhat of a minimalist feel, but you know, racecar. Two Bisimoto racing seats can be found up front, with a MOMO Prototipo placed in front of the driver. Behind the wheel lies an 11,000 RPM tachometer with a shift light. To the right and left are RS door panels, and a Porsche 997 shift knob can be found in the middle. The interior is finished off with a NASA spec chromoly roll cage, preparing this beast not only for canyon cruising, but legitimate track days.

All in all, this 2400 pound Bisimoto Porsche 930 with a 996 power plant producing 850 hp is nothing to mess with. With that much power, that little weight, and an engine sitting in the rear, this 930 will be doing wheelies with zero effort. But considering Bisi’s previous builds, he not only knows how to build the power, but also how to handle it.
