U.S. based tuner Switzer Performance is constantly looking for new ways of improving the Nissan GT-R, and their latest customized version of Godzilla packs no less than 900 horsepower and runs on…ethanol.
The Switzer E900 Nissan GT-R runing on E85 is ‘greeer’ than the petrol burning versions and the engine that features a new fuel system to handle ethanol had to receive larger injectors.
The Switzer E900 Nissan GT-R assures a linear power delivery and needs less than 6.0-seconds during the 60-130 mph acceleration and as you can imagine the transmission had to be adjusted accordingly.
At the exterior the Switzer E900 Nissan GT-R features a carbon fiber aero kit, and additional elements include 20 inch BBS alloys and a 3-way adjustable suspension.

Switzer press release :
When Nissan introduced the latest R35 version of its GTR Skylines in
2008, the international press was quick to nickname the car "Godzilla" –
as much for the car’s size as for its fire-breathing performance – and
Nissan was equally quick to call the car both "perfect" and "untunable".
That "perfect" label is a matter of opinion, of course, but enough GTR
buyers felt the car lacked sufficient oomph that a number of tuning
firms began to lay waste to the idea of an "untunable" car, building
massively-powerful GTR Nissans along the way. One such firm is Tym
Switzer’s Ohio-based Switzer Performance, and their massively-powerful
GTR is called the P800 – a comprehensively tuned 800 hp track-weapon
that’s as much at home on Main Street as it is on the back straight.
Of course, there are some enthusiasts who will always want more – and
when one of these enthusiasts contacted Switzer about pushing the P800
GTR to the limit, the crew at Switzer Performance got to work developing
the car you see here.
"The P800 is already at the limit of what we feel comfortable for the
stock GTR transmission," explains Switzer. "So to go further we really
needed to beef up the transmission. We contacted Dodson Motorsports in
New Zealand and explained what our goals were with the car – 900 hp,
more clutch area, ad smooth shifting at every speed. The new
transmission is the product of several months’ co-development between
Switzer and Dodson, and is exactly what we needed in order to start
pushing the GTR forward beyond 800 hp."
The next thing Switzer needed to address to keep "pushing the GTR
forward" was fuel. "We didn’t want to just deliver a race-gas package
that tethered the client to a fuel drum in his garage, but we wanted to
be able to turn up the boost, also." The solution? Readily-available
"In a way, the solution was all around us," offers Switzer, whose
shop is located deep in Ohio’s farm country, surrounded – literally! –
by cornfields. "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." The E85 delivered other benefits as well: it is significantly
"greener" than the pump-gas and race-gas versions of the GTR. "With most
high-horsepower cars, you can barely breathe after just a few dyno
runs. With the E85, we were able to run pull after pull to dial in the
tune without feeling any effects of the usual emissions. It’s hardly
scientific, but there was a noticeable improvement in the air quality in
the shop compared to race gas."
The final product – dubbed the E900 for "Ethanol fuel, 900 hp" – is a
fast, capable package that offers linear power delivery and massive
midrange torque with superior transient response compared to
larger-turbo/race-fuel combinations, while maintaining a bit of
environmental responsibility along with its blistering sub-6-second
60-130 mph acceleration.
This first P800 also sports an Amuse carbon fiber aero package, 3-way
adjustable suspension, and 20" BBS wheels that are an inch wider than
stock at all four corners. Switzer’s new E85-fueled E900 PKG is
available now. Contact Switzer Performance for more.
