Re Amemiya Proves Once Again That The FD RX-7 Is Alive And Kickin'

Originality is something Isami Amemiya-san knows a thing or two about. Over the years he has used the FD3S Mazda RX-7 as a canvas for his creations, and of these there have been many. But who could have prepared themselves for the Genki 7? Sitting in its low-lit stand at the main entrance of this year's Tokyo Auto Salon, it looked like something out of a sci-fi flick. Within minutes of the show's opening a crowd quickly formed around the RE Amemiya booth, with curious people taking a closer look at the RX-7 turned spaceship. It was then and there we knew we had to feature this car in full detail, as it was like nothing we had ever seen before.

Fast-forward a few days and we found ourselves at RE Amemiya's headquarters, a stone's throw away from Narita airport. The Genki 7 had already been moved outside and was being polished by Ken Amemiya, son of the great man himself. Ken, who's in charge of PR for the company, is always such a pleasure to chat with and is one of the most down to earth and humble people one would ever wish to meet. He told us his father wanted to prove that the RX-7 is not dead, and with this car hints at the future, something Mazda still hasn't done. This is where the name "genki" comes from, meaning "alive and well" in this case but using different characters to make it sound cooler and hinting at a future vision for the "7." Amemiya-san got to work on this project last summer and like all his show cars, went all out. The donor FD3S was completely stripped down to its bare chassis where it was prepared for paint. The same sky-blue pearl was used on the chassis as would be used on the body for that custom car feel. Once the chassis was done the long process of shaping the bespoke body began. First up was the front end, starting with the bumper, which was created into a one-piece part along with the front fenders. The front bumper extends quite visibly into a pointy front section where Amemiya-san formed a very slight center crease, which extends its way up onto the aero bonnet. A very simple yet aggressive central air dam was a necessity as it provides plenty of air for the V-mounted intercooler and radiator assemblies. A pair of rounded off triangular openings have been worked into the side of the bumper and are joined by canards which are said to help keep the nose planted at speed. The front lip protrudes to help further more with aerodynamics and is painted dark gray metallic to offset the blue body.

Complementing the front-end conversion are the custom headlights which are shaped on the very extremities and made up of bright IPF projectors and LED orange repeaters on the top part. From the Lotus headlights the fender section extends slightly over the bonnet line and down creating a thin opening behind the wheel. From these vents a massive widening of the door sections has been used to create a large double-intake on the rear fenders. The side skirts play a big part in highlighting this aggressive profile and are finished off with under skirt panels. The rear fenders widen the rear of the Genki 7 substantially meeting up with the custom rear bumper to form yet another opening, this time a vent that helps expel air when the rear wheel-arch coves are fitted. The rear bumper is quite a lot shorter than the standard item, and features a grilled number plate mount section and a simple under diffuser from which the new 2009-spec dolphin tail silencer pops out from. Twin afterburner-type rear LED lights are used to further enhance the unique look of the rear end, which also sports a custom rear hatch section.

The massive carbon spoiler and new 2009-spec side mirrors complete the conversion, but let's not forget about the wheel covers! This is a look we have seen before on RX-7s from both RE Amemiya and other body kit specialists but this time the whole cover look has been taken a step further with ones being fitted to the front wheels too! Obviously since the front wheels steer there was no way the front fenders could be closed like the rears so Amemiya-san drilled the rims of the brand new 19-inch Enkei GTC-01s and threaded in some bolt-on fittings. Here the covers, finished off in the same color as the body and sporting an RE-Amemiya logo, were bolted on to create a never before seen look! We had Ken remove them on one side so we could grab some shots with the wheels in view, a look we prefer far more than with the covers on. But each to their own, as they say. Ken actually told us that both the front and rear covers are road legal in Japan, however we don't see too many customers wanting to drill their wheels in a hurry. The lightweight Enkei GTC-01s are shod in brand new Yokohama Advan Neova AD08 tires, the replacements of the AD07. Finally Yokohama has decided to offer the Neova in 19-inch fitments, and on the Genki 7 245/35/19 are used up front with slightly wider 275/35/19 going on the rear.

As with every RE-Amemiya project you can be sure that when you lift the hood, chances are you're going to be treated to enough polished custom engine work to make you blind. The Genki 7, by all means, continues this tradition forward. The stock 13B the car came with was opened up and overhauled with a set of special RE Amemiya 3-piece Super Apex seals along with some side-porting to get proper performance out of it. Helping the 13B spin faster is the Trust TD07H-25G turbine kit, looked after by the Trust external wastegate, which dumps spent gasses into the Trust front pipe. From here the exhaust fumes are whisked away buy the RE Amemiya system which sports a new type of "dolphin" tail design. RE Amemiya's continuous collaboration with Trust means that a ton of parts are from the GReddy line up, like the Airinx air filter as well as the intercooler. The latter is fitted horizontally in front of the engine, efficiently using up the available space. A carbon air guide has been made around the core to help air flow out of the venting in the bonnet and also works when it rains, forcing water to flow down through the intercooler rather than spill all over the engine bay. This means no special shrouding has to be made on the inside of the bonnet, keeping things nice and simple. RE Amemiya took care of creating the custom piping, which connects to the GReddy inlet before the throttle. The factory intake manifold has been polished, like every other aluminium part, to a mirror finish. The GReddy intercooler is joined by a large-core radiator, which has been mounted in a "V" layout, making optimal use of the airflow coming in from the main air dam. The Trust oil cooler takes its position on the driver side intake and helps keeps those temperatures down, thanks in part to the special RE-SuperG oil which has been formulated for tuned rotaries thanks to RE Amemiya's years of Super GT experience. Feeding the upgraded injectors is a big-capacity fuel pump while the Sard FPR makes sure enough pressure is sustained at all times. Ogura Racing Clutch (ORC) was part of the Genki 7 project and therefore supplied the twin-plate clutch, which joins the RE Amemiya limited slip differential. With the GReddy e-Manage ECU in control, the Genki 7 develops around 480 PS. We realize this isn't crazy power, but understand that the car was finished for the Tokyo Auto Salon in a hurry; it will be making its way back to the shop for a full tune mapping session to get the most out of the side-ported 13B.

Since the Genki 7 will be getting beat on by Amemiya-san, the handling was set up with specially valved Quantum RS adjustable dampers coupled with Swift springs. These join the GReddy front strut brace as well as the underbody bracing done by RE Amemiya. On top of the clutch, ORC supplied their latest 4-pot front brake kit. The gold-anodized calipers are joined by floating 2-piece slotted rotors while the rear is left standard, but dressed up with RE Amemiya ORC-look plastic caliper covers. A very cheap alternative to an expensive brake kit, but not quite as good!

Open the doors of the Genki 7 and the blue theme of the body is continued inside with a fully decked out interior. The dark blue velvet-like finish is obtained by applying an adhesive to the surfaces and then firing statically charged nylon fibers on to it, which then attach and arrange themselves into a fine and smooth finish. This is the same technique as used on rally car dashboards, mainly done to avoid reflections onto the windscreen. The Genki 7 sports the treatment on the dashboard, transmission tunnel trim, pillars, headliner, door trim and the whole rear hatch area. Even the center part of the stock steering wheel is finished off with the blue velvety treatment. As Ken says, this is something pretty new on tuned machinery in Japan and something that we will be seeing a lot more of in the future. Blue Bride Low Max bucket seats were chosen to match the interior while RE Amemiya white and chrome instrumentation was fitted to the carbon-look dash. A triplet of Defi gauges are fitted on the passenger air-bag cover while the GReddy e-01 boost controller is neatly hidden away in the glove box. The Clarion MD/CD head unit completes what has to be one of the freshest looking interiors to date.

Amemiya-san has, without a doubt, proven that he is still the master rotary tuner he has always been. Yet at the same time he shows that the FD3S body can still be used to create exceptionally innovative designs. His son, Ken says, "My father will never run out of ideas of what to do next with the RX-7." We wouldn't have it any other way.
