R35 GT-R GT3 Promises Competition For Other Marques In 2012

Nissan-nismo-gt-r-gt-1w

No car enthusiast is unaware of Nissan's generation of Skylines, and of its latest iteration the R35. Although purists may claim that the R35 isn't a true Skyline because of its engine configuration, the fact is that the R35 offers extremely good value for its performance capabilities. Consistent with its goals of demonstrating the R35's track capabilities, Nissan, through its competition arm NISMO, began  a development program in 2010, with the aim of offering a customer GT3 racer by 2012.
Nissan-nismo-gt-r-gt-2w

To this end, NISMO entered into a contract with JR Motorsport to help develop the GT-R GT3. This is not a new venture for the two companies, as JRM already runs a GT1 R35 for Nissan. Nissan also runs a GT-R in the Japanese Super GT series, so the combined knowledge gained from running these cars will benefit the GT3's development. The FIA's GT3 rules are designed for competitive, yet relatively affordable racing. This is why this class has practically exploded, with entrants from Porsche, Ferrari, Aston Martin, to name a few.

Nissan will step into this arena with the GT-R GT3, using the production car's VR38DETT V6 twin turbo engine. Output has been announced at 530 horsepower. GT3 rules specify rear-wheel drive, so a Hewland transaxle has replaced the production all-wheel drivetrain. Note that the GT1 version uses an NA V8 and a Ricardo transmission. Even so, reports are that the GT3 is very close to the pace of the the GT1 in testing.

The weight of the car will be between 1250 and 1350 kilos, which makes it lighter than the Mercedes SLS GT3. Entered in its debut race at Magny-Cours in August, the GT-R GT3 finished 8th out of a field of 35 cars after 98 laps, or about 440 kilometers of racing. For a race car's initial outing, that is an outstanding achievement. Only 10 GT-R GT3 racers will be produced for 2012, with 5 earmarked for Japan and the remaining 5 for the rest of the world. One has already been reserved by an Australian team and further announcements will reveal where the rest will go.

Based on its initial outing, it looks like the R35 will continue with the dominant performance that have made Skylines such respected cars on and off the track.

Comical Cars Offer Serious Racing Action

Img_1807

If you're looking at this Toyota and it seems comically proportioned, that's because it is. This car is a competitor at the Aussie Racing series, which is a controlled-format series. All the cars are mechanically identical, although there are 5 body types to choose from. Aside from the Aurion, a competitor can select from the Classic 40 Ford, FJ Holden, Ford Falcon and Holden Commodore styles. The comical part comes from the fact that the bodies, and hence, the cars under them, are 50% smaller.
23201082258068_m

The cars are built upon a tubular space frame with an integrated safety cage. Suspension is via wishbone up front and a live axle at the rear. Coilovers do the damping work and 4-wheel disc brakes ensure reliable stopping action. Power comes from a 1200cc twincam four tuned to 125 hp with a redline of 11,500 rpm. A sequential 5-speed is the standard transmission. Yokohama 13-inch spec tires further ensure that the drivers are given appropriate performance that will showcase their skills.

Img_2873-560x373

Because the cars are so small and light (450 kilos, ready to race), their power-to-weight ratios are equivalent to that of an Aston Martin DB9 Volante or a Porsche 996 GT3. With a top speed of 230 km/h and a 0-60 under 4 seconds, performance is certainly substantial. In some circuits, cornering loads of 2Gs have even been recorded. Race series such as these are popular around the world. People who want to showcase their talents but are hampered by budgets can join these championships, where the cars are the tools that show which drivers are truly the fastest.

Mercedes Rally 500SLs A Very Rare Breed

227151d1236879745-missing-fact

Mercedes is recognized as a force to be reckoned with in most fields of motorsport. Its F1, DTM, Group C and other cars all made their marks in the circuit, bringing home race victories and innumerable trophies to date. But few know that Mercedes also campaigned in rallies for a time.
450slc799

Mercedes had previously campaigned SLCs from 1978 to 1980. For 1981, the factory decided that it would run the W107 500SL. Not a lot of build data is known, but it's been reported that the hardtop was welded onto the body, which also used alloy panels. No carbon fiber yet at that time. As part of the standard prep for a competition car, the interior was stripped, a rollcage installed and racing seats (Recaros) replaced the leather ones. The race prep resulted in a car that weighed 2930 pounds, which was more than 400 pounds lighter than the SLCs of previous years.
231446d1239107381-missing-fact

The 5-liter V8 was prepped to produce 380 horsepower, and although some accounts report that a manual transmission was used, other people claim that the 4-speed automatics of the time were used, with 1st gear locked out and setup to change gears in manual mode only. Effectively, it was a clutchless 3-speed manual. Horsepower calculations reveal a power-to-weight ratio equivalent to a Porsche 996 GT3 for these factory rally cars.
231448d1239108469-missing-fact

It's said that these cars represent the last of the true in-house racing cars, where everything from design, to engineering and then production was done by factory engineers and technicians within factory facilities. Less than 5 were made and one is confirmed to have been wrecked in testing.  It's too bad that this batch of cars don't even have competition records to their name as they were pulled out of the Monte Carlo rally after the recce, when the team manager was told that the cars had no chance of winning.

Hotrodding Ethic Extends To All Forms

Cb750_rigth_side2

Any true-blooded gearhead appreciates the many forms of mechanized transport that people all over take apart and remold according to their ideas and whims. Some people just seem to have a natural talent for putting together awesome builds, which is the case with this avid motorcyclist. One subset of the motorcycling world are the so-called cafe racers who mod their bikes according to certain design philosophies. The Honda CB750F Supersport  featured here made waves when it was first introduced, as it was one of the first big bikes that was produced with significant input from Honda's U.S. dealers.
Engine

The CB750 featured a transverse inline four with, up to 1978, a single overhead cam head and four carbs. Output was 65 horsepower driving 510 pounds.
To convert this CB750 Supersport into the cafe racer you see below, the area under the seat was opened up by reconfiguring and relocating the oil tank for the bike. Aside from this, the seat was removed and a seat that is more in keeping with the cafe racer look was designed. The tubing under the seat was reinforced with a steel plate to strengthen the frame and the battery was relocated to the speed hump. Underneath is a custom-fabricated tunnel that hides the electrical wiring.
Oil_cooler

The engine is stock for now, but an oil cooler kit (the heat exchanger came off a Cadillac Cattera) was added to enhance engine longevity, plus it allows a spin-on oil filter to be used. Even though the engine is stock, our horsepower calculator reveals that the power-to-weight ratio for this work of art would be equivalent to an Evo 8. Not bad for a project that cost $500 to start with and which won Best Japanese Modified at the Rockerbox show in 2009 with its white, gold and black color scheme.

Original look of the CB750F

Porsche 924 Conversion Preceded Ferrari's FF

924_03

Ferrari revived it recently with its FF and Mercedes is reportedly developing this body style that fell out of favor but had been the rage a few decades back. Known as a shooting brake, this body style evolved from the requirements of well-off hunters in the past who required a shooting platform on their carriages.
924_09

The shooting brake you see here may not be immediately recognizable as the Porsche 924 that it is because of the weird-looking rear section. But it's a wagon conversion that is only one of seven originally produced by German tuner DP Motorsport between 1998 and 2003. Modifications to the body included steel tubing extensions and a lengthened roof. The tailgate is made from fiberglass with safety glass being used for the extended rear section. The result of all the bracing made the entire car even stiffer than the Porsche 944.
Engine

Aside from a complete refit for the interior section at the rear, the fuel filler neck has also been relocated. The drivetrain remains stock, but since descriptions describe it as a superfast wagon, it's safe to assume that the base car is a 924 Turbo. Distinguishing features were a NACA duct on the hood and 15-inch wheels, which this wagon has. Not easily seen are the uprated suspension and 4-wheel disc brakes to handle the 170 hp turbo motor. In today's high horsepower environment, it doesn't seem much but it's worth noting that the 924 Turbo had performance close to the 911 SC.
924_05

Today, Audi's RS4 and RS6 would be the epitome of sport wagons. But the DP Motorsport shooting brake stands as a unique development for the 924, so much so that an additional number were reportedly produced because of insistent demand.

Lexus V8 In A Lowly Corolla Produces Potent Weapon

800-2

When one talks about Corollas in the drifting world, it's usually about the AE86, which made a huge impact then and is still being used today by serious competitors. When this up and coming drifter wanted something unique for a new drift car, a Corolla was also his choice, but the shell was not an 86 but an AE71. And rather than using the normal powerplants like the 4-AG or the SR20, the engine choice was a 1UZ-FE, which is an engine normally found in Lexus sedans.
Post-19701-12706189688968_thum

Like any serious competition build, a straight body was needed, so the AE71 was sourced from an owner who had his car for many years, stock and untouched. The body was in mint condition, so much so that no unnecessary labor was spent on patching up rusted areas. Apart from the norm of installing a rollcage, the body was also seam-welded to take the stresses of competition. Major front suspension components like the lower control arms, steering rack, hubs and even front crossmember were from Nissan's S-series Silva, while the rear uses the original 4-link solid axle setup with upgraded components like a Hilux diff.
Post-19701-12669679689492_thum

What makes this car truly unique is the choice of Toyota's 1UZ-FE engine. As we said, it's normally found in cars bearing the Lexus branding. But this V8 quad cam engine actually has design elements copied from an Indy Racing League racing engine, with it 6-bolt mains, hypereutectic pistons, 32-valve heads and oversquare engine design permitting high revs. Displacement is 4 liters and stock output is a little under 260 horsepower.

This Corolla's V8 did not stay untouched for long and now has high compression pistons, oversized valves, 286 degree duration cams, uprated fuel injectors, an individual throttle body setup and some cylinder head mods.  Haltech's Sport 2000 ECU controls the engine functions and a 3-inch exhaust handles the spent gases.  Horsepower calculations and dyno runs confirm that output is over 360, which should be enough power to run with the big boys.

Post-19701-12737961067571_thum

The owner of this car started drifting at age 14 and with his new tool should be able to show much older competitors that Falken made the right decision in sponsoring him.

Wife-inspired Truck Wows Crowds

Dsc_0127

Whether you want to admit it or not, American car culture has produced some of the most uniquely thinking hot rodders and enthusiasts on the planet. There is a reason hot rods are emulated in all corners of the planet, one of those reasons being taking what you have and creating a unique work of automotive art that is unlike anything else anywhere. Who can resist building a hot rod and claiming, in truth, that it's the only one in the world. Such is the case of this 1944 Mack truck that has been made into a truly unique vehicle in the finest hot rodding tradition. The inspiration for building this hot rod came from the owner's wife who suggested a fire truck as a vehicle for a project. Found on eBay in Pennsylvania, the truck was shipped to Precision Designs in Colorado.
Wheel

In true hot rod tradition, the engine has been replaced, this one being from a 2005 Dodge Viper SRT10 that pumps out 500 horsepower. Although the engine is stock, a Mopar competition ECU was used. A Dodge 48RE automatic works to handle the engine's torque and the truck's weight, which should be a lot less since a lot of firefighting equipment has obviously been removed. As are most most of the original underpinnings, which gave way to Viper SRT10 brakes and a Dodge Ram truck rear axle. The springs gave way to airbags, which makes it possible for the truck to ride so low to the ground.
Interior

The driver's cab is open to the elements with the top removed and an elegant leather bench seat adorns the interior. Chrome 24-inch Mack-badged wheels peek out from under the fenders. The truck's firefighting origins are still evident, but the black coat and striping clearly show that this truck's working days are done. Unless it's to wow crowds at the different car shows the owner chooses to attend.

Racing Fiat Of Old Won Championship Thrice

Fiat_131_abarth_rally_alitalia

Today’s generation of enthusiasts may not be aware of it, but Fiat was once a world power in World Championship rallying. One of the company’s greatest creations was the diminutive 131 Abarth. It was based on the 131 sedan introduced in 1974. However, Abarth versions of competition Fiats were radically different and the 131 Abarth was no exception. Built as a homologation special, around 400 examples were built. From these 400, an initial 40 were selected to become works rally cars, with another 10 built up at a later date.
Engine2

As opposed to the live axle rear suspension of the 131 Mirafiori from which it was based, the works 131 Abarth featured an independent rear suspension damped by Macpherson struts front and rear. The engine was also radically different, being a DOHC 2-liter featuring Kugelfischer mechanical fuel injection, dry sump lubrication and electronic ignition. Output was 215 horsepower.

Fiat131abarth_cut

The body was clad with lightweight body panels, but due to differing tarmac and gravel specs plus continued development, body weight varied from 980 kilos for tarmac to 1030 kg for gravel. Fully laden and with driver and navigator on board, weight distribution was 50/50. It’s worthy to note that a third Safari-specific body spec was also built. At the time the Safari was part of the rally calendar, all the major competitors had versions just for that rally. It was that kind of race.

131victory1

If we compare the power-to-weigh ratio using our favorite horsepower calculator, its modern-day equivalent would be that of a Lotus Elise R or a Lancer Evo 8. Not too shabby for the day then. In fact, it was a terrific combination that allowed it to win three World Rally Championships. Today, the newest Fiat to wear the Abarth name is the 500. It’s a far, far cry from the glory days when European makers pulled out all the stops for rally championship glory.

What Kind Of Car Would A Bugster Be?

12

Engine swaps are a dime a dozen, even from decades back, although some swaps and builds are still noteworthy enough that it catches the eye of jaded car nuts, such as Honda's VTEC engines in an old-school Mini or a V8 engine in a Miata. Or even a V10 engine from a BMW M5 into the engine bay of an M3.
091

But how often do you hear of a chassis swap, specially one involving the old VW Beetle? Well, this build came about because a VW Beetle lover happened to glance over at his wife's Porsche Boxster S one day and realized that the Boxster chassis would fit under the Beetle's. So with the requisite research into the dimensions of both cars and some careful measuring, the decision was made to weld an entire Beetle body onto the floorpan of a Boxster S.
Idee_23_fs

Twe years of work were taken up by the build, as the Boxster S is a modern car complete with electronics and other safety features. One particularly important goal of the build was to retain all the driving dynamics a Boxster S provides. In addition, it was also deemed important that the conversion make use of the ABS, ESP and safety systems like the airbags.
Rollout_6_fs

The builder says that output is slightly up due to intake/exhaust and ECU optimization. Performance calculations peg 0-100 km/h at 5 seconds. From afar it can lay claim to be the ultimate sleeper, but even slightly knowledgeable people will notice at once the lack of the familiar aircooled clatter and the deeper growl coming from the back of the car. Purists will say that this conversion is so wrong but to hotrodders and modifiers everywhere, it's just so right!

Greek Tuner Shows Engineering Knowledge That Silences Naysayers

Katara11

Claiming you have the Lancer evolution engine that makes the most power will surely start a flame war on the internet where there are plenty of legitimately knowledgeable people but also keyboard warriors who don't know much except to disagree.
Frondleft1

Understandably, the initial claims of Extreme Tuners in Greece were laughed at in some forums until the owner Spyros showed some impressive dyno charts and pictures of custom-made turbos made from billet aluminum with titanium wheels. And metal matrix connecting rods. Plus custom-machined cylinder heads sporting titanium valves and beryllium valve seats. All based on a billet aluminum engine block.
Katara41

The particular Evo 8 pictured here had 1400 hp at the wheels at the time it was publicized, based on the horsepower calculations resulting from the dyno pulls. It made a 9.3 in the quarter-mile, which, while fast, is slow compared to what some Evos were already doing. But as Spyros points out, they are an engine building facility, so dialing in the car is not really their purview. And if one wants to be picky about it, there is no proper drag strip in Greece that allows drag cars on slicks to hook up properly.
Cylinder

It's a good thing to enthusiasts in general that tuners like Spyros have customers who can afford his wares. Even in a community that is well aware of the costs of modifying the Mitsubishi 4G63, using all this billet, custom-machined hardware undoubtedly costs a fortune. Unlike race engines built to class rules, extreme street cars follow no rules, so Spyros is free to explore the limits of design, materials and engineering. Already, he has developed 2500 horsepower kits for this type of engine and we should see more extreme feats of engineering from him in the future.

Carbon R35 Uses WTAC For Developmental Effort

14

Built in time for the World Time Attack Challenge held in Australia is this Autogarage / HKS Australia R35 GTR. Stock, the R35 is a giant slayer, giving established marques a run for their money. But as with any form of motorsports, you have to match your competitor's work on their cars, otherwise your efforts will be in vain.
09-07-2011-021

So with this in mind, the owner of this car started the development of this R35 with, as you can see, no expense spared. While the build was successfully finished in time for the WTAC event, the builders fully intend this racer to be eligible for other events worldwide. For starters, complete model of the front, doors and rear of the car was made in order to fabricate a complete carbon fiber body. Then, an FIA-approved rollcage was welded onto the stock chassis rails. Custom HKS coilovers, fully adjustable suspension components and Project Mu rotors and pads rolling on Volk TE37 18-inch wheels complete the chassis mods.
Carbonr354

Although 500 horsepower, is plenty for the street, the car's time attack competition sport 700 horsepower engines on chassis 200-300 kilos lighter, so the builders' horsepower calculations showed that 800-1000 horsepower was needed to be competitive. The engine uses custom CNC-machined heads, HKS rods and pistons, ceramic-coated manifolds and a GT800 turbo kit to achieve this goal. Other stuff includes an HKS F-CON controller, a 2000-hp rated fuel pump and 2000 cc injectors. The stock transmission's internals have been upgraded to cope with double the power.
Carbonr351

The weight goal for this car is 1250-1350 kilograms although as we mentioned, the competition will be fielding 1050 kilogram cars. Still, it's obvious that this is only the first year of the car's development and its 9th place in the 2011 WTAC can only improve with all the track and testing data the team will surely accumulate in the near future.

RX-7 Build Values Balance Over Outright Horsepower

Re7b

There's a reason one of the favorite tuner cars is the Mazda RX-7. The combination of its balanced handling and turbo rotary make for a very entertaining car that with a few mods, can handle many more high performance cars. Even though the RX-7 has long been out of production, a lot of Japanese tuners still choose the last version of this platform, known as the FD3S, to showcase their wares and knowhow. In this case, this particular car is from RE-Anemiya, famous in Japan for its string of RX-7 buildups, which have put even 650-horsepower R35 GTRs in their place.
Engine

Built for the popular touge events in Japan which take place in twisty and narrow mountain roads, this car has already proven its top dog credentials by winning quite a few events. Touge cars are completely built machines which value horsepower, handling, braking and driver skill in equal measure. As an indicator of the principles guiding the build of these cars, this particular RX-7 has “only” 400 horsepower, which RX-7 enthusiasts will know is still way below what a modified rotary can produce. For this build, the OEM twin turbo setup was retained but the intercooler was upgraded and then repositioned to give the shortest possible routing through the system. The goal here was minimal turbo lag instead of outright power.
Wheel

DG-5 coilovers replace the original shocks and springs while Brembo calipers and two-piece rotors make up the front braking system. The rear brake setup uses the original calipers but sees the rotor replaced with a high performance component.
Wing

The rest of the car has the requisite aero add-ons for maximum downforce, as well as a few carbon fiber bits like the hood and wing to help lighten the car. The rear end was revised to shorten the overhang although the aesthetic qualities of the mod leave something to be desired. Most of the mods performed were done in view of the requirements of the car’s chosen event but even so, the balanced upgrades were enough to make this car a winner.

Tuner Adheres To Lotus Founder's Lightness Mantra

Forced-fed-lotus-elise-10

Forced Fed, a tuning firm out of New York, recently made the news when it offered for sale a cut-up Lotus Elise that had a bevy of aftermarket parts and mods such as an Eaton supercharger, Ohlins dampers, Alcon brakes and a Quaife diff among a host of modifications. This tuner has made a few outrageous Lotuses and in the course of doing so has garnered significant experience in tuning these lightweight cars. Stock, the Lotus Elise is a well-balanced and sprightly car, due to the company's continuing devotion to the founder's principle of making a car go faster by adding lightness.
Fig2

Forced Fed offers multiple tuning packages, ranging from a 275 hp Stage 1 kit to a 400 hp kit. Whatever the package, the modifications include upgraded engine internals and better oiling to the Toyota-derived 2ZZ engine. A video of a blue Elise with the 400 horsepower Forced Fed turbo package has a reported performance of 0-60 in 3.4 seconds, with a quarter-mile time of 10.56. And since it's a Lotus, it outhandled a Ferrari Enzo in a 600-foot slalom, hitting a speed of almost 74 mph compared to the Enzo's 71 mph run. The tuner says that it has accumulated more than 350 hours developing these packages and does not plan to sell these as kits, but as complete dealer-installed packages to maintain quality.
Forced-fed-lotus-elise-14

Since this orange Elise doesn't have a publicized weight, we can't do a reliable horsepower calculation but this tuning firm has undoubtedly adhered to the principle of making the this Elise go faster by not only adding lightness but also by upping horsepower.
