One of the more anticipated cars of this year’s WTAC among fans and builders alike, had to be Beau Yates’ revamped AE86. With Mark Bissett leading the team, the car was built at Hypertune in Sydney, and has been entirely stripped of it’s former drift specification and rebuilt as a time attack car fit for a king; and by king, I mean none other than Keiichi Tsuchiya. Keiichi was slated to drive the car in Open Class this year at Sydney Motorsports Park.
Among the top N/A competitors in the Japanese time attack scene, exist a niche group of AE86 drivers. Serving as the FR rival of the Honda Civic’s in the paddock, the competition provided by the Toyota pack always manages to provide a subset of antagonism at any given event. Sato Shinetsu and his CBY equipped Trueno did just that at this year’s 10th anniversary Attack Championship at Tsukuba.
During the Option Fuji Superlap, the Supra meisters from the Tokyo based Material Auto Factory had the most prominent display of JZA80’s in attendance. Some were competing in the main event, others competed in the Hiper Challenge, and some were on display at their booth. I had highlighted Tatsuo’s Supra in our previous coverage, and a viewer had spotted another of their cars in the background that had piqued their interest.
There’s no doubt that, in Japanese motor sport, one name stands out among the rest. In almost everything they do, they need to be on top. The fastest, the most advanced. HKS will stop at nothing to collect these titles, and the TRB-03 has become their newest vessel to achieve them. The company has enveloped it’s priority in the project with the goal of being nothing less than the fastest around Tsukuba’s TC2000. It was even re-branded as the ‘Tsukuba Record Breaker’, from it’s original designation as the GTS800; a tip of the hat to it’s capped power level (which is debatable…). The car has been through extensive testing over the past year, and last weekend at HKS Day, I was able to finally get a closer look at it.
I guess since we’re on the topic of mid-engined roadsters (although technically only the Elise, not the Exige, was roadster), rarely seen in the Japanese Attack arena, now would be a good time to post up some shots of this MR-S. Owned by Masahide-san, and tuned by the foremost MR-S tuners in Japan, Techno PRO Spirit, this is one of the only of it’s type in the Attack lineup. It’s aggressive exterior is backed up by some pretty formidable times at TC2000; a 59.4 to be specific.
Without a doubt the most interesting thing for me, in following Japanese Time Attack so closely, is getting to see the progression of builds over an extended period of time. We all know that building a race car isn’t a quick task, and for most people at the grassroots level it’s a trial and error procedure; you find out what works and what doesn’t from your initial base, and head back to the drawing board after each event. Everyone has their own method of going about this, but the common goal for everyone, however, is to go faster.
Senkichi has modified his JZA80 specifically to handle the variety of turns at Tsukuba. Each modification that he chose was specifically tailored for TC2000. The engine’s drive-train has been upgraded and the bottom end built to handle the extra boost from the T78 turbine. Transmission gearing has been modified to put the car in the exact power range needed for each turn. Check out the results below.
