Top Secret Final Evolution V12 Twin Turbo Supra







Top Secret, one of the famous japanese tuning company in worldwide, had made this supra into their newest demo car & wangan machine. This supra had radical changes for its engine, platform, exterior & etc...

Smoky was tired of waiting for Toyota to announce the plans for the new Supra so he did it himself. Ironically, Toyota unveiled its FT-HS concept around the same time as Top Secret's golden child halfway across the world at the North American International Auto Show in Detroit. Toyota's concept is a hint at what the automaker might offer as either a replacement for the Supra or a next-generation of the model. With a 400hp hybrid 3.5L V-6, it's safe to say that Toyota went in a slightly different direction than Top Secret's double boost V-12.

The only hybrid thing about the Top Secret Toyota is how Smoky successfully mated a V-12 to a Supra. Consider that this engine is the same length as the original 2JZ-GTE Straight-6 with an additional bank of six more cylinders set in a V formation. Now add two turbos with all of the necessary plumbing and you wonder how it all fits.

Even more impressive than the swap itself is where Smoky actually sourced his V-12 donor motor. The engine is normally found in the Toyota Century. The Century is a $90k home market luxury sedan and in factory guise the 4,996cc 1GZ-FE makes a mere 276hp. Smoky added a matched set of HKS GT-RS turbines along with one of his seductively shapely Top Secret custom intake plenums with twin 80mm throttle bodies. One concession to the reduced real estate within the engine bay is with the placement of the cooling system.

The ARC intercooler is angled into the front bumper to make room for the V-12 but this leaves no room for the ARC radiator-it's in the trunk along with a massive fuel cell (alas, Jonny's bike will never fit in there). Each quarter window gives up a fine piece of glass to make way for custom ducts leading to the radiator with twin puller fans sucking the remaining hot air out through a vent in the rear bumper. No doubt a custom bellhousing was required to mate the factory JZA80 Getrag six-speed gearbox to the massive 1GZ. An ORC clutch and Cusco 1.5 way LSD will help put down the projected power to the pavement once Smoky completes the build. That's right, this beast is under construction.

Oddly enough there is not a big tuning demand for Toyota V-12 luxo engines and Smoky will be forced to create custom one-off internals in order to achieve the 1,000hp rating he wants for this car. Why 1,000hp? Because this is the number Smoky feels is needed for him to take this car to 400 km/h (249 mph). Unlike every other story in Super Street, I am not making this up. Smoky wants to one-up his CV35 Skyline, which ran 341 km/h (212mph) on Germany's Autobahn. That top speed prompted the 400 km/h goal for the Supra and the necessity for the 1,000hp rating. But you need more than just power to rocket up to almost four times the speed that Ricky's Accord cruises on the 405, you need aerodynamics.

In addition to big tuning and big motors, Top Secret is known for its big, beautifully sculpted aero kits. Because Smoky loves speed-scorching highway runs even more than tire-smoking burnouts he places a high-priority on high-speed stability. Each Top Secret aero kit is designed to offer enough downforce to keep the vehicle planted at high-speeds but not overly so to restrict the car from reaching those speeds. This same compromise is applied to the aero work found on the world's leading sports car racers such as those in Japan's Super GT series. But Smoky prefers a clean street-styled look over the harsh, angular, tacked-on feel of a GT500 machine. The Top Secret Super G-Force Wangan widebody kit for the Supra supports this design philosophy.

The 33mm front and 50mm rear over fenders blend artfully with the factory lines, but the Top Secret GT rear wing looks a little ricy. However, with 249mph speeds in store for this wing I'm sure it serves much more of a purpose than the bi-plane combat model atop the hatch of some Hot Import Rice tC. As part of the Super G-Force Wangan kit the headlights are the most polarizing part of the car. Some think them hot, others not, but no one can argue against the futuristic conceptual look these eyes give to the Supra, which is what Smoky was going for in the end.

The rest of the Supra is standard Top Secret fare with little more than leather-clad Bride Gias seats, Takata harnesses, a Top Secret wheel and a Defi Super Sports Cluster to complement the clean factory look that Smoky favors. The footwork is also pure Smoky-style with GREX stoppers and Top Secret coilovers equipped with the Roberuta Cup kit which offers in-car height adjustability. Finally, the Supra's shoes offer a new spin on things. The 19-inch Bridgestone Potenza RE050A tires may be some of Smoky's all-time fav' rubbers but the Volk GT-Fs are a new model finished in the Top Secret Exclusive gold.

With a $500,000 estimated value, Smoky is not sure whether he would sell this Supra or even build another if a customer makes such a request. But there's only one client who should think about purchasing this car and that's Toyota itself, if only to give it's designers the proper inspiration to take the next generation Supra in a direction it desperately needs to go.
