Even in this configuration the numbers are astonishing. The boosted 1GZ churns out 650 ps, thanks in part to the custom engine management system made up of two HKS F-Con V Pro ECUs and a set of Neko AF700 oxygen sensors. Nagata has big plans for this engine and work has already began in the development of custom engine internals to allow the 1GZ to rev up to 7,000 rpm (1,000 rpm up from stock) and take significantly more boost. The target was set at over 800 ps, not a very precise number but with hardware like this it wouldn't be surprising if the final figure reached the magical 1,000ps benchmark.
This Supra was built to be a comfortable yet fast road car and there will no doubt be a few high-speed trials to see if it can beat the 341km/h that the V35 GT-R project achieved at the German Autobahn in 2005.
The V-12 Supra project was also undertaken to take the Supra model aesthetically to a new level. As a final goodbye to the JZA80, Top Secret designed and built a complete widebody kit called "Final Evolution." The 600,000 Yen kit has already captured the imagination of many Supra owners and Top Secret is overwhelmed with orders from both Japan and overseas. The kit was designed with a very angular feel, much like modern-day Lexus models and concept cars. The factory headlight clusters were binned and replaced with original Top Secret projector-type items, completely altering the front-end look. A long-snout front bumper with a large central opening joins the lights together with the aggressively flared arches to create a totally bespoke look. A vented bonnet helps extract air from the engine bay or, in this case, the V-mounted intercooler and oil coolers. The angular-design is carried on to the side via the deep skirts and is joined with the flared overfenders.
Also part of the kit is the rear bumper, which completes the Top Secret conversion with an abundance of air outlets to keep the radiator happy. The main radiator air intakes are located near the B-pillars where the small side window used to reside. A Carbon rear wing joins the Ganador mirrors to complement the "Final Evolution" JZA80 look.
Shot with Bridgestone RE-01R rubber, Volk Racing GT-F 19-inch wheels were painted with gold highlights to match the Top Secret color scheme. Making it hard to miss is a huge GReddy 8-pot bake kit up front and 4-pot kit at the back with matching gold calipers and center bells. The V-12 Supra has been lowered thanks to a set of Top Secret Aragosta adjustable suspension.
Keeping with the idea behind this project, the interior hasn't been stripped out but dressed up to make it a comfortable place to be. A Pioneer double-DIN HDD navigation unit and full speaker system takes care of the entertainment, while occupants are cosseted in lightweight, carbon-shell leather Bride bucket seats. Other toys include the new-generation HKS EVC boost controller and Defi Super Sports Cluster dash unit - both integrated seamlessly into the dashboard. Opening the glovebox you'll find two HKS F-Con V Pro computers and AF-700 lambda displays, while the Top Secret steering wheel and gear knob finish things off.
We're eager to see how this V-12 Supra project develops and if Smoky can turn it into his fastest road project ever. With Smoky's track record it is only a matter of time befor that happens.
