When a customer request came in to pull even more power out of Tym Switzer’s already monstrous 800-hp P800 tuning package for the latest R35-version of the Nissan GT-R, the Ohio-based company had to look at other ways to extract performance from an already well-utilized engine. Nissan declared the GT-R both “perfect” and “un-tunable” soon after the car was launched in 2008, and it was only the desire for more oomph and a yearning to tinker that so many shops like Switzer’s shop began to lay waste to the idea of an “un-tunable” car, building massively powerful GT-Rs along the way. The solution to Switzer’s newest problem wasn’t quite as simple but was, in fact, all around the shop—literally.
“In a way, the solution was all around us,” offers Tym Switzer, whose shop is located deep in Ohio’s farm country, “E85 isn’t without its trade-offs. We had to modify the fuel system to handle the fuel and significantly increase the size of the injectors, also, but in the end we had a fuel that gave us everything we needed to crank up the boost on this car and deliver over 900 hp.”
Its next problem was the transmission. It simply couldn’t take the strain from the new high-horsepower engine. Swizter decided it had to beef up the transmission. The new transmission is the product of several months’ co-development between Switzer and Dodson Motorsports in New Zealand, and is exactly what it needed in order to reliably push the GT-R above 800 hp.
The final product—dubbed the E900 for “Ethanol fuel, 900 hp”— is what Switzer describes as a fast and capable package that offers linear power delivery and massive mid-range torque with superior transient response compared to larger-turbo-and-race-fuel combinations, while maintaining a bit of environmental responsibility along with its blistering sub-6-second 60–130-mph acceleration.
