10. Honda CR-Z Mugen RZ

Like the 2012 SEMA Show in America, the 2013 Tokyo Auto Salon was packed with Toyota and Subaru’s latest sports car. But that’s not to say that there weren’t plenty of other attractions on the Makuhari Messe Convention Center show floor. 

Coming in 10th on our list of Top 10 Cars of the 2013 Tokyo Auto Salon is the Honda CR-Z Mugen RZ. Perhaps what the CR-Z should have been from the factory, minus the rear spoiler, the Mugen RZ is a supercharged hybrid powered by a 1.5-liter, four-cylinder with 153 hp. Five-away adjustable coilovers give the CR-Z the sporty handling it deserves, while the body styling gives the CR-Z a much more attractive design. Too bad Mugen is only planning on selling 300 of them.

It wouldn’t be the Tokyo Auto Salon without an appearance by a few specific tuners and that list includes Top Secret. Best known for building unmistakably gold high-powered machines – like the Toyota Supra – the Top Secret display in Tokyo this year includes a stunning Nissan GT-R.

Sporting a special aero kit (including a carbon fiber front splitter and large rear spoiler) the GT-R gets the gold treatment and is accompanied by two Honda CR-Zs as well as a Suzuki Colt. None of the cars are close to stock and the dark gray CR-Z even has an HKS turbo kit.

Check out all the cars (and a few extras) in the gallery below. And see our complete 2011 Tokyo Auto Salon coverage here.

Oh how much we love Top Secret’s signature gold finish on their cars. We were actually disappointed in how long it has taken Top Secret to show off a Nissan GT-R doused in their gold, but boy was the wait worth it. But as you may be able to tell from the above photo, Top Secret has also finalized and released their new front bumper replacement.

We’re digging that Top Secret kept the styling on their front bumper quite subtle, incorporating a carbon fiber front diffuser while making it just slightly more aggressive than the OEM bumper. Best of all, it’s very functional, providing additional cooling for the oil cooler and the front grill giving direct additional cooling for the intercooler. The bumper is also slightly longer to give the car better aerodynamics.

It all comes at a hefty price though, with the front bumper and diffuser being offered at $4,350. But for those looking for something that not only enhances the performance of the vehicle but also changes the look, without being too drastic, it’s a great option. While you’re at it, you might as well toss yourself another $4,000 into the budget and get the car repainted Top Secret Gold. Yum.

Looks like HKS isn’t the only kid on the block looking for big horsepower gains with Honda‘s newest cool hybrid, the CR-Z. And perhaps this really solidifies a changing of the times considering Top Secret is well known for their wicked drift cars and high horsepower 350Zs and Supras. They’re also well known for their blistering high-speed test runs, so to see Smoky Nagata of Top Secret working away on Honda’s ZF1 hybrid powerplant shows that hybrids and tuning are going to go hand-in-hand for decades to come.

Aftermarket manufacturers are going crazy out in Japan over hybrids and seeing what Top Secret is developing for the CR-Z is slightly astonishing. We can’t quite decipher what’s going on from the magazine snippet – and would love if someone could offer us a translation – but Top Secret is definitely underway in producing a single turbo upgrade and even has a titanium induction kit, oil catch tank and tow hook out to the public now. The stuff comes at a price though, with $995.00 as the MSRP for the Ti Induction kit straight from Japan.

We’re sure many enthusiasts are still rolling their eyes about the idea of a hybrid being turbocharged or supercharged. But let’s face it: every automotive manufacturer will be working on developing hybrids for the future to fill out their lineup with mpg-friendly cars. It’s only natural that the aftermarket will find ways to make these eco cars more fun.

Nissan‘s resurgence with the Z model has been quite a hit and the 370Z has been the perfect successor to the ever-popular 350Z. With the VQ37HR powering the way to a more streamlined body, it’s no surprise that the aftermarket has embraced the 370Z with open arms. While there are tons of nicely built 370Zs in America, it’s always nice to see what’s being done in Japan as inspiration of fully functional, cleanly built cars.

Most enthusiasts often find it sacrilegious to mix and match parts from various manufacturers when it comes to building their car. Perhaps it’s just brand loyalty or a fancy way of keeping a clean spec sheet, but we don’t always run across cars like this. Instead of sticking to just one brand for the entire vehicle, this owner mixed and matched with what he/she thought looked best on the 370Z. The result? A Top Secret front spoiler with integrated brake ducts has been combined with Varis twin carbon fiber intake ducts and Varis carbon fiber hood. On the hood are Top Secret aerocatch hood pins and in the rear is a carbon fiber wing from Mine’s. And outfitting each corner are none other than Volk Racing’s TE-37 wheels in a classic white finish enhanced with a blue pinstripe on the lip.

One thing’s for sure, every part of the car is a nice high quality component from a reputable brand in Japan. While we’re more used to seeing full out Top Secret cars, or full Varis cars, it’s refreshing to see someone break the mold a little bit, blending the best of all worlds for a great looking car.

There’s a sort of an irony in the Top Secret brand name; they’re not one bit a secret in the tuner world at all. There are few companies that have stood the test of time like Top Secret has, always being on the forefront of parts research, design and manufacturing. They are also one of the few Japanese tuning companies that focus on all facets of motorsports from street driving to drifting, circuit racing and even drag racing.

Mostly known for their infamous gold paint schemes on their demo cars, Top Secret’s products are available for a multitude of makes and models. But it’s hard to argue their passion for Nissan tuning, exemplified with their 350Z and previous Skyline projects.

Now attention has turned to the new Godzilla GT-R on the streets, the R35. Top Secret has recently announced the release of a few new parts, some of which could be great interest to any GT-R owner. The most important of the releases is a twin turbo upgrade that surprisingly uses the stock housings but honed out to fit the larger internals. Top Secret claims that they’re good for around 600-hp without sacrificing drive-ability. Ball-bearing maintains the quick spool the GT-R is known for.

The Top Secret Super Suction Kit is a 56mm stainless steel intake that replaces the factory compressor-side cast offerings. It can be used with the stock intake kit. Accessories from Top Secret this time around include an oil catch can with a 2.0-liter capacity and a hood dampening kit. Nissan made an odd decision to not include gas struts for hood support on their premier street car, but hey at least Top Secret has us covered now – and in style.
