Don’t we all dream of the perfect 360-degree car. One unique enough to stand out and attract attention at a show, but at the same time be a functional performer both on road and track. Does such a thing even exist? If you ask Kohei Miyata, he’ll tell you he may have built something that comes pretty damn close...
Being in the second-hand car business for years has allowed Kohei Miyata to play around and build a few interesting cars, from a four door DC2 Integra to a USDM S2000 he still owns. But the craving to step away from Hondas and play with something very different materialised initially as an idea – or shall we call it an approach. He had a vision in his mind of creating the perfect rotary. One that would tick so many boxes, his friends were saying it just couldn’t be done.
Either you build a show car, or you build something to be driven, but combining the both just never really works – that’s the message he was getting. But he knew it could be achieved and after waiting for the right car to show up in the market, he teamed up with N-stage in Yokohama to begin the build.
The key to making this car work is balance. Each detail and modification had to have an element of function to it, starting off with the engine bay. N-stage pulled the 13B and literally took a grinder to the metal and started cutting. A ton of fabrication work went into reconstructing wider and taller tubbed wheel arches to allow wheel clearance under full lock, taking into account the very dumped stance the FC would end up with. While they were at it key areas in the engine bay were smoothed and cleaned up, with some wire tucking added for additional points in the presentation category.
While the little twin-rotor motor was out it was given its due attention, but again taking things pretty conservatively. There was no need for aggressive porting, just a basic power bump thanks to the addition of a Trust TD06 turbo. This was plumbed on along with a supporting fuel system made up of top of the line Sard parts. Once it was all in place N-stage fabricated a one-off V-mount set up with the intercooler and radiator so as to take full advantage of the copious space in front of the engine and thus getting the best possible path of air through both cores.
The custom intercooler piping connecting up to a better-flowing FD3S intake manifold while the RE Amemiya titanium exhaust system beautifully completed the set up. A trusted and proven Apexi Power FC was swapped in place of the vintage eighties electronics and custom mapped to get a solid and reliable 350bhp and 253 pounds of twist to play with.
N-stage also took care of some more additional fender work, a little bit or rolling, a little forced persuasion for a few added millimetres of extra girth. An AR-F bumper was thrown on as well as some rare online sourced items from the good old US of A in the form of USDM mirrors and side markers, something the Japanese like to do as much as the Americans like to emulate the JDM look. Funny how that happens. I put it down to human nature: always craving what one can’t easily get.
Anyway, the work continued with good old-fashioned sanding, getting rid of the base paint and creating the smoothest possible finish ready for a fresh few coats of paint. Kohei decided to go for a Nissan colour, the Millennium Jade hue as used on the 1000 Nür editions of the V-spec II and M-spec. The result is an FC like you’ve never seen before, a subtle colour that emphasises those eighties lines with a touch of modernity. The final touch were USDM emblems on the tailgate.
The current AutoStrada Modena 5-spokes are the second set of wheels Kohei has run on the car and it’s really impossible to fault them in any way or form. The Ferrari-esque feel about them being a superb match. They wheels are shod in Falken, which a visible ‘hippari’ – or stretch – to them so that the sidewall folds inwards as it tucks into the arches. The lowering is courtesy of drift oriented Tein dampers mated to hard 20kg/mm front and 18 kg/mm Swift spring to make sure the car doesn’t bottom out under hard compression.
Supernow camber joints helped Kohei dial in the perfect drift set up, and not just so he can talk about it when he’s showing his car at static events. He enters drift events in Nikko and other circuits quite often. So yes, the function part of this whole build isn’t just a theory. It gets put to work just as often as Kohei can manage to get it to the track.
The final piece of the puzzle was the interior, the most simple part of all, spiced up only with small additions like the aluminium half roll cage and the plush Efini seats that were one of Mazda’s luxury sub-brands from the early nineties. A Renown Monaco steering wheel and an FD shift knobs are the only other party pieces, and if you look, the Power FC controller is always within hand’s reach, to keep an eye on those important engine parameters.
So is it possible to create a functional show car that can be used in anger shredding tyres at Nikko on Saturday and then wow people at Stance Nation on a Sunday? We’re pretty sure Kohei really has managed to pull off the perfect 360-degree build.
