Tuner TommyKaira is exhibiting their R35 GT-R at the Tokyo AutoSalon this Friday. After many hours of hard work on the part of TommyKaira staff, visitors will now be able to see the fruits of their labour.

Two kit choices are available, the first being a very comprehensive one while the second just works on the front end. The full kit consists of, among others, a wet carbon front bumper, a front grille cover, lip spoiler, under diffuser, side ducts and side skirts. The rear also features wet carbon in the form of a racing diffuser, a rear wing and rear fender extensions. The AVS Model F15 Platinum black wheels are shod with Pirelli P-Zero 255/40R20 and 285/35R20 front and rear tyres respectively.

Optional dry carbon components can be fitted. These include front fender finishers, ducts and door handle surrounds.

A more minimalistic Front Style Kit is being marketed for customers who prefer not to go over the top. It is made up of wet carbon for the front bumper, grille cover, lip spoiler, under diffusser and side ducts.

Not much info regarding the interior was announced, only that it is completely red and covered mostly in leather.

There are other components that were developed such as a high performance titanium exhaust as well as a brake and suspension kit.

LSD Design released information on their new wing doors for the Nissan GT-R. The creatively named LSD Flügeltürbeschläge, which is not actually a good choice for a “safe word” with your dominatrix, is one more step in the quest by aftermarket parts makers to customize every Nissan GT-R that comes off the line.

We kid, of course. “Flügeltürbeschläge” loosely translates from German as a more multisyllabic way of saying “fitted wing door.” For €1949, you get the accessory with roller guides, to guarantee precision every time the door is opened or closed. The guides are also adjustable, to ensure the best fit possible. Also nice is that the doors can bolt on pretty easily, “without welding and paint work,” according to the design firm.

These wings are much easier to use than they are to pronounce, since the company used the original mounting points that Nissan used. When getting out, simply open the door slightly outward, and let it go up in the air. Closing the doors is done in one fluid motion.

The wings are now commercially available. Sadly, you will probably not be able to score a license plate that says “Flügeltürbeschläge”.

NISMO has put together this tuning package for the Nissan 370Z. Virtually every Nissan performance car gets NISMO enhancement at some point in its lifetime. At the moment it is the 370Z coupe’s time.

The same 3.7-litre V6 as used in the 370Z has been tuned to produce 350hp (257kW), up from 332hp (244kW). Torque reaches its maximum of 276 lb-ft (374Nm) at 5,200rpm. The only gearbox offered is a close-ratio 6-speed manual with the Nissan “SynchroRev Match” function.

The car’s body structure is very tight and rigid which works well for handling and cornering, yet at the same time it features dampers which soften some of the harsh blows from road input. The car is fitted with 5-spoke Nissan-branded alloy wheels with P245/40ZR19 front tyres and P285/35ZR19 in the rear.

From the outside one can spot a NISMO 370Z by its extended front nose, chin spoiler, special side sills, vertical door handles, rear spoiler and wide fenders. The NISMO name is splattered across the interior in places like the seats and the tachometer.

Standard interior features include a radio/ CD audio system with four speakers, Nissan Intelligent Key with Push Button Start and automatic climate control.

The Renault/ Nissan alliance has benefited both companies quite well since it was formed. More mutual benefits are set to take place in the coming years after a rumour surfaced that Dacia will model its first ever SUV after the highly successful Nissan Qashqai. Dacia is owned by Renault.

According to Masini.ro the Dacia brand will exploit its relationship with Nissan by using some of the components and dimensions found in the Qashqai for the production version of its Duster concept.

The Duster concept was unveiled at the 2009 Geneva International Motor Show. It is 4.25 metres long, 1.49 metres high and uses a 1.5dCi engine with 105hp (77kW) and 240Nm of torque. The design is quite revolutionary for Dacia and includes highlights such as high-mounted side mirrors and wraparound rear lights. Interestingly the Dacia SUV will not be connected to the Sandero Stepway.

Ohio-based tuner Switzer Performance has announced details regarding their new P700 package for the Nissan GT-R. Designed to enhance the car’s already stellar powertrain, the package consists of a series of high-performance bolt-on accessories that give the GT-R plenty of extra power without sacrificing reliability or drivability.

The biggest change comes in the form of the addition of new turbochargers that were specifically designed for the high-performance GT-R. Switzer also added a new “MONSTER” intercooler package as well as a retuned ECU module which allows for extra boost.

Thanks the revised setup, the new P700 performance package produces over 700 horsepower at the crank which translates into an extraordinary 626 horsepower and 583 lb-ft of torque when used with 93 octane. For comparison, the standard Nissan GT-R comes equipped with a 3.8-liter twin turbo V6 engine which produces 480 horsepower and 430 lb-ft of torque.

Pricing for the Switzer P700 package is pretty steep as it retails for 16,650 USD, about the same price someone would expect to pay for a mid-size sedan.

Following some unsavory reaction to the Nissan GT-R-based HKS GT570 Racing Package as far as the eco brigade goes, the tuning firm has responded by releasing an HKS GT570 Sports Package. The previous package wasn’t too environmentally-friendly as it was not fitted with catalytic converters. This made it illegal in some countries.

HKS went back to the drawing board and now offers a new kit for the GT570. It consists of stainless steel catalyser midpipes, aluminium intercooler piping, an EVC electronic boost controller and Super SQV blow off valves that come with the piping kit.

The turbo has been fitted with upgraded wastegate actuators and Super Fire Racing M45HL spark plugs are added to the engine. Revised power figures are not available but the Racing Package makes a heady 570PS (419kW) and 540 lb-ft of torque at the wheels. The addition of “road legal” equipment shouldn’t make too much of a difference in performance though.

Pricing for the kit is about ¥913,500 (US$9,700) in Japan which is close to ¥315,000 (US$3,300) more than the Racing Package. That’s the HKS price for going clean.

Shadow Sports Design has given access to details regarding its Nissan GT-R conversion. The car has been given a number of new parts to enhance its performance. A carbon fiber rear spoiler is fitted and elevated to improve downforce. There is a rear air diffuser installed as well for the same purpose.

The 20-inch wheels are made of forged magnesium for both strength and lightness of weight. These were developed in conjunction with Enkei and each of the front wheels saves the car 2.05kg in unsprung weight. They are available in either black or a gunmetal finish. As a way of helping to cool the front brake calipers the front underspoiler has carbon ducts that lead directly to these brakes.

Titanium was the material picked when it came to manufacturing the exhaust pipe mufflers. The Shadow Sports Design GT-R has a pair of racing seats fitted with a harness. No performance figures have been released yet but it’s been said that the carbon-clad official GT-R Spec V is two seconds faster around the Sendai Highland Raceway track in Japan than the standard car.

Wald International has officially introduced their new body package for the Nissan GT-R.  The Japanese tuner has not released any engine modifications, citing the “difficulty in tuning the GT-R’s engine.”

The company has created several carbon-fibre body parts to lighten the vehicle’s weight and make the car more aerodynamic.  They custom built a front-lip spoiler and nose cover, and rear wing.  Low-drag duct covers from another lightweight composite material are in place, while under the hood the cutomer will find a carbon-fibre engine cover.

Wald’s aero-kit comes in the glossy finish typically used for street cars, called wet carbon fibre, or a dull matte grey color, called dry carbon fibre.  The second choice is usually used on racers.  A wet carbon kit starts at 1,039,500 yen ($11,620), with the dry carbon kit going for about 2,362,500 ($26,410).  Prices include taxes.

Japanese tuners Zele International have released details of their modified 2009 Nissan GT-R called the Zele R35 GT-R Complete Edition. The carbon fibre menace has been tweeked out with an aero kit, bumpers, front and rear spoilers, and side skirts. The air ducts, grille, and side mirrors have also been revisited. Carbon fibre is also used for a roof.

Unveiled today at the 2009 Tokyo AutoSalon, the production car is based on a prototype shown off at SEMA last year. Using carbon fibre for the body and titanium for the exhaust, the tuner has shaved weight from the car in almost every conceivable place.

But front and center is the engine tuning, which sees output increase to 550hp. Inside, Recaro seats covered in Alcantara have replaced the stock seats. The car itself sits on new 20-inch black alloys, which contain a large set of brake pads. An upgraded suspension is also included.

And if you do not want the bright orange colour choice, Zele says that is no problem. The company offers to create and mix any metallic or pearl colour their customers desire.

Only eight Zele R35 GT-R Complete Edition vehicles will be released. Pricing begins at 18,880,000 yen ($208,000). This is 3,130,000 yen ($34,500) more expensive than Nissan’s GT-R SpecV. Delivery of the Zele R35 will begin in March.

Other Japanese automakers must be green with envy at Nissan’s current success with the sports car genre. Tuners on the other hand, salivate each time the Japanese car maker is mentioned. Branew is one such tuner. Also based in Japan, Branew plans to launch a very comprehensive tuning kit for the new Nissan 370Z at the Tokyo Auto Salon in a couple of weeks’ time.

Branew developed a new sports exhaust for the car, reprogrammed the standard 332hp 3.7-litre V6’s ECU, upgraded its brake system and added a new sports suspension kit. Carbon fibre exterior kit includes front spoiler, side steps, rear spoiler, a rear air diffuser and a rear wing. Multi-spoke alloy wheels will be offered in various sizes for that final touch of performance.
