Switzer Ultimate Street Edition GT-R
Weekday Warrior
Los Angeles Auto Show
A Nissan that is too quick for your average joe.
The feature of this weeks issue. An astonishingly quick & street legal beast.
A insight into what well may be the future automotive industry.
Switzer Ultimate
What would you give up to have a 1,000 horsepower, 9-second street car? Would you concede to having a stripped out interior? Would you surrender the A/C, heater or stereo system to save weight? Would you be okay with forking out big bucks to only fill up with race gas? Would you sacrifice boost response for the top-end power needed to put up the number?...
Ten years ago, a die-hard performance enthusiast would have had little choice in the matter. If he wanted that performance level, sacrifices would have to be made. Today, that same level of performance can be obtained without any of those concessions. Now, it is possible to have a 1,000 horsepower, pump gas, daily driver that can run 9-second quarter miles on radial tires through a full exhaust system and endure bumper-to-bumper traffic without complaint.
Meet the Switzer Performance Ultimate Street Edition GT-R. This GT-R delivers over
1,000 crankshaft horsepower on pump gas, clicks off 9-second quarter-mile times and
includes all of the original creature comforts installed by the factory. Tym Switzer sums up
the philosophy behind the vehicle in these words, “For those who want a 1,000+ horsepower car
that they can drive comfortably every day, to the track, to the office or the grocery store, on the highway
or in bumper-to-bumper traffic, we’ve built this car.”

SWITZER ULTIMATE
While doubling the original output of any engine would usually require a myriad of performance parts, the Switzer Performance Ultimate Street Edition upgrades consist of only the parts needed to get the job done. As strong advocates for the exceptional engineering behind Nissan’s VR38DETT engine, Switzer Performance only upgrades the parts that have proven to fail at 1,000 crankshaft horsepower. In the short block, you will not find aftermarket sleeves. “The VR38DETT isn’t a B-series Honda engine that needs to be cut apart and sleeved to handle boost.
The VR38DETT is the best-engineered turbo engine to ever come from Japan. We’ve realized an exceptional level of reliability and performance by simply removing the few weak links,” says Tym. The weak links in the VR38DETT are replaced with custom Carrillo forged steel connecting rods and Mahle forged-aluminum pistons. These simple upgrades along with a careful blueprinting of the entire engine assembly provide the strength to allow the block to handle 1000-horsepower operation with OEM reliability.
PUMP’NPOWER
DOUBLE UP
Giant turbos, high boost pressure levels and high-octane racing fuels are a proven formula for high peak horsepower numbers. Unfortunately, that combination is usually best for a dyno queen. For an actual daily-driven vehicle looking to maximize performance from pump gas, it takes some careful selection of turbocharger designs, internal engine improvements, fuel system upgrades and engine management solutions to deliver an exceptional power curve.

The quality of the power curve delivered by the Ultimate Street Edition GT-R is phenomenal. Over 500 lb-ft of torque are on call at 3,700 RPM, 600 lb-ft at 4,000 RPM, 700 lb-ft at 4,400 RPM, 730 lb-ft at 4,700-to-5,200 RPM and over 600 lb-ft of torque until the 8,000 RPM redline. The downward sloping torque curve from 5,200 RPM to redline provides “automagic” traction control as the reduction in torque output as engine RPM climbs won’t induce wheelspin. If you have traction at 5,200 RPM (which is a factor of grip level, gear selection and boost level), you’ll still have traction

WORDS BY ARNOLD EUGENIO ARTWORK BY DANNY MURPHY
When Edwin Diaz needed something with four doors to replace his heavily-modified RX-7 project, he turned to one of the most potent import performance sedans on the planet, the EVO. “I needed a 4-door family car that was comfortable enough to take my daughter Bella anywhere without any reliability issues,” he remarked. Diaz decided the turbocharged 4B11T engine mated to Mitsubishi’s smooth-shifting Twin Clutch Sporttronic Shift Transmission (TC-SST) was the answer to his daily family-transportation question.

After replacing the modified RX-7 with the 2008 EVO MR here, Diaz missed the admiration he previously received in his “fast-looking” car. In response, the initial round of modifications to the EVO MR focused on aesthetic upgrades. “I built toward a JDM look. Not because I think it’s the best there is or because
it’s JDM’. I simply like the styling,” he explains. To that end, Diaz installed several Varis carbon-fiber aero pieces including a vented hood, front lip spoiler and rear diffuser. He added Chargespeed carbon fiber side skirts and a roof-fin vortex generator to round out the aero enhancements.
Looking The Part
DSPORTMAG.COM 11
The EVO wore several wheel and tire sets during Diaz’ search of the perfect combination for street and occasional track duty. Currently, 19x10.5-inch Volk Racing TE37s carrying Nitto NT-555 drag radials fill the wheel wells. JIC-Magic FLT-TAR coil-overs control the wheels and tires over the bumps. These coil-overs offer individual corner height adjustments to allow the EVO to be properly corner-balanced after setting the desired ride height. The 15-way mono-tube dampers also feature 15 response curves allowing for “softer” street friendly settings or
“harder” track settings that sacrifice ride comfort for performance. Diaz’ considerably low stance preference for his EVO x created a number of issues including errant suspension geometry and an increase in bump steer. A set of MoonFace roller center adjusters (modified tie rod end links) correct the geometry, subsequently reducing bump steer. Cusco sway bars and end links reduce body roll while a Cusco ender brace and Beatrush strut tower bars minimize chassis flex. This flex reduction improves both ride quality and suspension efficiency.

When it came to adding power, Diaz reminded himself of his original intention, grocery getting and transporting his daughter. “The goal was to keep it simple and reliable,” Diaz states, “but, being a chronic car enthusiast, minor modifications started happening here and there. The car soon looked more track-inspired than street car.” While trying to follow the spirit of his original intention, Diaz reasoned that any engine performance upgrades would be in the name of improved efficiency and reliability, not extreme performance.
Factory head gaskets and head bolts are not designed for the prospect of enthusiasts doubling the factory horsepower output. When turbo engines are pushed hard, the factory head gasket may fail due to a lack of adequate clamping force. Looking to avoid this issue, Diaz opted to upgrade the factory head bolts to ARP head studs to increase the clamping force on the head gasket. Once the cylinder head was secured to the block, Diaz next upgraded the cams. Camshafts are the conductors of all valve events, The lift, duration, ramp profile and timing of the camshafts influence power output, fuel economy, emission and the width and location of the engine’s power band. To increase the efficiency and expand the power band of the 4B11T, Diaz replaced the factory cams with a set of Jun Auto 264-degree camshafts. Diaz installed high-rate valve springs and titanium retainers to properly control the return of the valves to the seats.
Add-on Head SeeingAddiction Honcho Red
Since Diaz would drive the car on the street 99-percent of the time, he narrowed his turbocharger choices down to stock-replacement or “sport turbo” selections. These turbos would bolt in the factory location while supporting faster spooling characteristics and increase power at street-level RPM ranges. After some research, Diaz selected Forced Performance’s Diaz selected Forced Performance’s FP RED turbocharger. This turbo spools fast while producing more power than the stock turbo. A ball-bearing center section and twin-scroll configuration allows the FP RED to deliver the goods.

Boost NeighborsWith a new turbo taking the lead, a new supporting cast was in order. A complete ARC-branded intake charge air system consisting of front-mount intercooler, matching intercooler piping and aluminum air box replaced the factory units. To meet the fuel requirements of the larger turbo, Diaz employed a host of HKS and SARD fuel components. With all the components in place, Diaz’ EVO registers 480 whp at its 7,600 RPM peak on a Mustang Dyno all-wheel-drive dynamometer on a diet of 93-octane pump gas. A stock EVO MR on the same dyno delivers 240 whp for comparison. To validate the goal of making a true street car, Diaz’ component selections and corresponding engine-management tuning allow the EVO to produce its peak 368 lb-ft of torque at a very usable 4,900 RPM.

To increase the efficiency and expand the power band of the 4b11t, Diaz replaced the factory cams.
Diaz enjoyed his well-thought-out horsepower increases and chassis and suspension upgrades for some time without incident. Soon, the desire to push the power envelope manifested in a lead foot that ultimately led to the demise of the original twin-clutch Getrag box. Undeterred by the setback and boosted by the feeling of being close to completing his build, Diaz opted to reinforce the replacement transmission before installing it. Where AWD transmissions at this power level are concerned, the clutch packs are usually the main point of failure, as was the case in Diaz’ TC-SST. An aftermarket upgraded clutch pack kit and transmission cooler were incorporated in the rebuild. The transmission cooler extends the life of the wet clutches by keeping the transmission fluid temperature in the temperature range that delivers the best protection.

Diaz drives his EVO MR daily to commute and to transport his most precious cargo, his daughter Bella. “She has been my inspiration for everything I do. In fact, she is the one that convinced me to go with the Phantom Black and carbon fiber components because she likes how the combination looks, “Diaz explains. While the incremental performance additions have slowed down, Diaz still works on the vehicle’s appearance. Of course, each modification requires Bella’s approval. One day, Diaz hopes to throw keys of his EVO to his daughter, Until then, Diaz plans to enjoy each day that this 480-horsepower monster takes him and Bella out on the town.

Given the cost of fuel today, it’s no wonder that fuel economy and efficiency sit high on many consumers’ wish lists. As a result, small-displacement turbocharged engines have been gaining favor among manufacturers. There are now a number of vehicles delivering over 30 MPG highway efficiency while offering a forced-induction starting point for enthusiasts to build upon. Don’t be surprised to see all OEMs moving toward smaller displacement engines to meet stricter mileage standards while relying upon turbo charging to still deliver performance when the pedal meets the metal.
Honda announced its new Civic for 2013, including a top of the line Civic Sport Si. The Civic Sport Si will face some strong competition in the performance FWD arena. Adding to its European-inspired releases, Ford’s 2014 Fiesta ST will showcase a turbocharged 1.6-liter Ecoboost engine. The other Big Three manufacturers are also addressing the sport compact performance market. Dodge added a Rallye edition to its Dart family, while Chevrolet joined its domestic brethren with the turbocharged 1.4-liter ECOTEC engine powering the 2013 Sonic RS, as well as its concept cars, (the Code 130R and Tru 140S). These concepts fit into the same class as the MAZDASPEED3, Genesis Coupe, FR-S and BRZ. On the European front, Mini unveiled two new versions for 2013, the Paceman compact utility vehicle and the Clubvan micro-van. In response, Fiat launched three new models, including an Abarth convertible and a 500 Turbo that fills the space between the standard 500 and the Abarth. Like bugs? Volkswagen showcased two Beetle variations including the Beetle Turbo and the R-Line upgrades.
