Every automobile serves a purpose to its owner. To the vast majority of drivers this purpose is as basic as it gets, an appliance that moves you comfortably and safely from point A to point B. To a smaller percentage of automobile owners, their mode of transportation has a bit more significance; some sort of sentimental value is involved where there is a desire to make their vehicle more than just a commuter. Those who fall into the second category may devote more time into keeping the car looking its best, a little more of their paycheck changing or adding parts to the car in an effort to get it to perform better than it was designed to from the factory. A third category of owners—the smallest percentage yet—includes those who devote their entire careers to building cars to fulfill their absolute potential. This category creates the parts the rest of us utilize. Hideki Takaku of Reverse is one of these people, an individual who took his passion to the next level and allowed it to become his career.
Reverse Racing Technology Supply is a full service shop located in Tochigi, Japan, known for their expertise with all things GT-R. Their original parts line, Seed, offers everything from aero and suspension components to exhaust manifolds for a variety of cars as well as an engine overhaul menu for the RB26 and SR20 engines. Reverse is also very active in grassroots motorsports, sponsoring drivers meeting events and listing upcoming open track days on their website, so it comes as no surprise that this ’92 Nissan Skyline GT-R is a machine built to run laps around a circuit in the least amount of time possible. Having previously owned a very impressive list of cars including an R33 GT-R, S13, S14, R32 GTS-T, and even a JZA70, Hideki is no stranger to his current platform of choice. He shared with us that the R32 GT-R was his dream car since he was much younger, and at 37 years old it was finally time to make that dream a reality.
Immediately after purchasing the car, he stripped it down completely to spot-weld the chassis, opting not to run a ’cage. The lack of a rollcage in a build of this caliber may seem odd, however you notice such a minimalist approach with this car in its entirety. On a car that has been completely spot-welded, the addition of a rollcage has a much smaller effect on the rigidity of the chassis in comparison to a car that has not been treated in any way to increase strength. If the sanctioning body in which you compete in does not require a ’cage, then it simply becomes a matter of personal preference. In this case Hideki chose to keep the weight of the car down and allow himself the luxury of keeping all his pristine interior panels intact. A Sparco steering wheel, HKS shift knob, and Seed bucket seats were chosen in favor of their stock counterparts when reinstalling the interior, and a Carrozzria head unit provides a little entertainment when driving to and from Tsukuba Circuit or perhaps just to the grocery store.
The exterior has been decked out in Shorin x Reverse GT aero parts. When such beautiful pieces are being created in-house there really is no reason not to replace every applicable panel of the car with FRP. The stock front bumper is kept, joined by a lip spoiler and carbon air diffuser. The side skirts and rear half spoiler are also Shorin x Reverse GT pieces. A Seed carbon GT wing completes the aerodynamic enhancements for the car and looks amazing in the process. Hideki performed all the bodywork on the car, fit the aero, and laid down the paint—the color of which he described only as “white”. Somehow the bright orange-and-gray graphic scheme manages to look simple and to the point, keeping with the understated theme of the car.
Orange CE28Ns wrapped within Yokohama Advan AD08s fill out the wheelwells in such an aggressive way that only a truly functional wheel and tire setup can, while providing a frame for the artwork that is an Endless racing brake system fitted to all four corners. Adjusted 60mm shorter when compared to stock, the HKS Hipermax III sport coilovers are the centerpiece of the suspension. Considering that the spring rates are only a couple kilograms per millimeter stiffer than what HKS offers as standard equipment, it’s plain to see that this is a very fast street car rather than just a street-able track car. Cusco sway bars reduce body roll, while Seed pillow-ball bearings (having replaced the stock rubber bushings) keep the alignment constant throughout the entire range of travel. An HKS Kansai strut tower brace up front adds even more rigidity to a crucial part of the chassis while a Seed brace does the same in the rear.
The RB26DETT engine has become an icon since its introduction in the R32 GT-R over 20 years ago, so it comes as no surprise that this car is powered by the same engine it came equipped with since birth—however, with a few changes. The bore and stroke of the engine have both been increased (87mm and 77.7mm respectively) by a fully counterbalanced crankshaft, H-beam connecting rods, and oversized pistons—all manufactured by HKS—effectively bumping displacement to 2.8 liters. The ported and polished head has become the new home for a pair of HKS camshafts and a set of valvesprings. Twin HKS GT2530 turbos pull air through HKS intakes before forcing it through an HKS intercooler and piping, excess pressure is released through an HKS blow-off valve. Fuel is pumped from the tank by two Nismo fuel pumps, through a Nismo fuel pressure regulator and into the Tomei fuel rail where it awaits to be released by 1,000cc HKS injectors. Okada Projects Plasma Direct Ignition coils power HKS M45 spark plugs, which ignite the mixture that is then immediately expelled from the engine through Seed 45mm exhaust manifolds and a Seed metallic catalytic converter before leaving the car. This equates to 710 hp with the HKS EVC 5 boost controller set at 26 psi. That rotational force is then transmitted through an HKS flywheel, triple-plate clutch, six-speed “dog mission”, and a Cusco LSD before reaching the ground.
Like every car in the world, this GT-R serves a purpose. Unlike most cars, this Nissan was built to set course records. Amongst its many achievements, this GT-R has won the HKS Hiper Challenge and the Second Annual Tsukuba Super Battle. For years, the Tsukuba Circuit has been the unofficial proving ground for major tuning companies and small shops alike in Japan. Goes to show just what the car, a simple lap time, and the builder in question is capable of. The Reverse-Seed R32 GT-R has not only recorded a very respectable time of 59:382 seconds around the famed circuit, but managed this feat on street tires, Yokohama Advan AD08s to be exact. This car is a perfect example of what dreams are made of: Hideki realized his dream of one day owning an R32 GT-R and didn’t hesitate to create it into the monster it is today. The build is sure to inspire many future GT-R owners, each car with its own purpose. Not a bad way to spend $10 million yen.
