With upgrades to the engine, it's no surprise NAMS put time and effort into addressing the fuel system and engine management. Using six Denso injectors, the four Bosch fuel pumps running in parallel series supply the adequate fuel necessary through an aluminum fuel cell shoehorned in the trunk of the Skyline. Keeping fuel pressure to a consistent level, a NISMO fuel pressure regulator keeps the RB engine content. NAMS leaves all engine functions under the watchful eyes of an A'PEXi AVC-R, to maintain consistent boost levels, and A'PEXi Power FC to ensure fuel tables and ignition timing is running at optimal conditions on the track.
Dubbed as the all-purpose track car and test vehicle on newly developed components for NAMS, special attention was paid to the BNR34's suspension and transmission components. A true testament in race proven products, a Hollanger six-speed sequential transmission and EXEDY triple-plate clutch enable the Skyline to tear through the race circuits without a hitch. Experimenting with numerous limited slip differentials on the vehicle, NAMS dialed in their setup with three-brand combo. On the front of the Skyline resides a CUSCO differential while the center is a NAMS special, and finally the rear implements an OS GIKEN differential. Suspension components consist of special one-off Tanabe Sustec Pro coilovers and NAMS pillar mount bushings. Implementing a slew of NAMS "original" products, the Skyline sports NAMS pillow tension rods, front lower control arms, upper control arms, rear toe rods, rear lower control arms, traction rods, a fender brace and traction rods.
Using their off-the-shelf, track tested products, the Nagisa Team was able to record impressive track times at three very different sanctioned locations. Locking down competitive times for the R34 is nothing new with the Nagisa Team. At the TI Circuit AIDA, which was designed for F1 circuit racing in Okayama, Japan, the BNR34 lapped a best time of one minute, 35.387 seconds on February 18th, 2004. In a mere 20 days, the crew was back at the tracks on March 9, 2004, this time taking place at the Central circuit in the Hyogo Pref. The Skyline stopped the clocks with a time of one minute, 20.537 seconds. The most popular event to take place among manufacturers is the Time Attack at the Tsukuba circuit where the team battled out it out with a blistering 57 seconds. No joke to the competitive world of racing, the NAMS team proved their products are more than just "pretty" products.
Aiding in the traction department, a set of 18x10.5 front and rear RAYS Gram Lights fit snugly over the AP Racing six-pot (390 mm) slotted rotors in the rear. In the rear resides a two-pot (333 mm) N1 Brembo calipers with Seidoya metallic race pads.
Just how serious the teams race mentality is truly evident with a crack of the door. The team removed all unnecessary factory components to make room for a cluster of switches and gauges that now fill the Skylines cockpit. The POWER FC commander is located on the center cluster and helps fine-tune the vehicle's engine management. The original gauge cluster was replaced with a Max Racing digital cluster, displaying engine RPM and speed, among other features deemed important when barreling down the track. To aid in weight reduction, carbon fiber replaces much of the interior-a full carbon-fiber dash, carbon door panels-and the car went through a grueling strip diet. A BRIDE seat with NAMS low profile brackets enables the pilot to obtain a lower center of gravity. Protecting the driver is a 10-point custom cage built by none other than Nagisa Auto.
If you know a thing or two about Japan and their racecars, nothing on the exterior of the car stays stock for long. NAMS implemented a NISMO body kit to accentuate the Skyline's natural curves while a fresh coat of custom silver was slathered on the BR34's stout body. In a quest to improve aerodynamics, a carbon-fiber Autoselect spoiler and canards reside up front while a GT-style carbon wing and trunk lid by Daishin keeps the rear firmly planted when reaching high speeds. Adding originality to the vehicle is a set of Nagisa Auto "original" LED taillights. The final touches include Craft Square carbon mirrors and a graphics scheme done by Nagisa Auto Motor Sports.
What's in store for NAMS in the future? Owner Sugihara-san ssays he wants to break the Tsukuba record currently held by HKS and their TBR-02 Evolution: "Our lap times are a few thousands of a second behind the Auto Select's Skyline record so with additional tuning and dialing in the car we are sure we will be able to make our mark in the 2004 season." With a smile Sugihara-san says, " Be sure to keep an eye out for the NAMS Skyline this year." Rest assured boys. You bet we will.
