Components external to the engine include a Toyo radiator with Trust radiator hoses, keeping H2O temps to a minimum, and a three-inch A'pexi core and associated titanium intercooler piping for the intake charge. The oil-frothing issue is dealt with by twin Trust oil coolers, hidden inside the bumper. Fuel management is delegated to twin Bosch OEM Nismo pumps, which flow downstream to some thirsty Sard 720cc injectors, where pressure is regulated via a pressure regulator of the same make. Combustion happens, and more than 900 horses are sent through a Nismo transmission with a twin-disc OS Giken clutch and lightened flywheel. Then it is transferred through a Nismo carbon propeller shaft, where it meets with a 1.5-way ATS carbon LSD. The current set-up had been dynoed at the wheels to push in excess of 680 hp at 6,800 rpm. Maybe not earth-shattering power in the realm of Skylines, but enough to achieve a record-breaking lap at Central Circuit of 1:31. Again, balance is the goal of Morita's creation.
Speaking of balance, the boys at NRS installed a set of proprietary Crux dual-adjustable coilovers with a set of 15kg springs, front and rear. To combat chassis flex, a set of Nismo anti-roll bars were employed, along with a set of Cusco upper tower braces. Nismo hard rubber bushings minimize LCA movement and spherical bushings are used liberally to tie in suspension points that won't adversely affect the street ride. Addressing safety and chassis stiffness, a Cusco Safety 21 roll cage is welded into key structural points. Most just stop at stitch welding. During its fourth rendition, however, while skewered onto a rotisserie, the GT-R received aircraft-grade rivets, and structural foam was used to further strengthen various crevices within the pillars and floor.
A massive set of 15-inch Alcon brakes (normally reserved for Super Taikyu cars) slows the car prior to corner entry. For street use, the R32 wears Advan A048 255/40-17. For track duty, the tangerine/bronze killing machine ditches the 17X10.5 TE37 for a set of SSR Type Cs, wearing a set of Toyo R1Rs of a similar size.
With the liberal use of exotic components, hand-laid carbon-Kevlar, years of careful tuning, and multiple trial and error renditions, we believe Morita has made giant strides towards achieving the balance he desired. It's people like him that the RB26 community will thank for being real-life test beds. Oh and the Kevlar doesn't hurt the eyes, either.
