Scoot Four-Rotor 1993 Mazda RX-7 with FEED Widebody

A four-rotor engine and a widebody you probably forgot about

Where do epic builds come from? We suspect (and we tend to know a lot of things) they come from one of two places: a company with large budgets or from the underdog enthusiast who spends every paycheck and weekend on his or her project car over the course of several months, if not years. Robert Green's RX-7 is the latter and appeared out of nowhere like a unicorn, surprising those who walked thought the Meguiar's Car Crazy booth at SEMA. We're always trying to deliver the freshest content around, and if this car doesn't get you as excited to do the Hotline Bling, we're doing something wrong.

Strangely enough, the cars that get the most attention are the ones that execute body modifications outside most people's comfort zones. In Robert's case, he envisioned something with an exotic feel and something Japan could only provide. We've seen RE Amemiya conversions, TCP Magic kits, and Rocket Bunny widebodies on the FD3S, but one name that has been out of the limelight for some time now is Fujita Engineering Evolutional Development, also known as FEED. It's probably because its widebody kit was introduced 10 years ago. We haven't seen many examples in recent time, plus Robert's kit is only the 12th kit ever sold in history and the first to be installed in the U.S. How's that for rare?!

The Version Victory kit completely alters the front end with an evidently wider body while ditching the pop-up headlights and adding Fujita Engineering's redesigned lights.

If the aero doesn't impress you, the rotary powerplant under the hood just might do the trick. As cool as the factory twin-turbo 1.3L rotary is, it's been succeeded by a four-rotor built by the hands at Scoot Sports Japan. You might remember Scoot when it stuffed a four-rotor into Yuki Kamakura's famous white RX-7 featured in last year's Japan issue. Robert's 26B pumps out a similar figure with 400 whp. Let that sink in for a while... No turbo or blower, just pure engineering perfection to 9,000 rpm! Getting this sort of awesomeness into Robert's FD was no easy feat by any means. With the language barrier, Robert communicated with Koseki from Scoot via Google Translate. It was frustrating at times with constant miscommunication and eventually dealing with customs, which resulted in taking two years from ordering the engine to actually receiving it. When the rotary arrived from Japan, Robert still had a checklist of things to do, including assembling the engine, which was handled by Formula D driver Kyle Mohan. The front subframe also had to be modified for the steering rack to clear the engine. Robert enlisted Bisimoto for a custom exhaust while the guys at Lucky 7 Racing tackled the electronics, which included a custom Mil-spec harness.

The car started for the first time a week just before SEMA and was loaded with a base map so it could be driven in. But don't think its sole purpose is to hard park; an Ikeya Formula sequential shifter with a Cusco twin-clutch system overrules any suggestion of the car being a show queen.

The interior is made up of quintessential JDM components from Takata, Works Bell, and Key's Racing, but what really stands out are the Technocraft seats. They are constructed using Kevlar and weigh only 6 pounds. As backbreaking as they look, Technocraft designs the spine to the backside of your normal torso, resulting in a comfortable fit.

"I wanted to build something unique. The more 'big' modifications I acquired, my vision became even clearer, but I didn't want to comprise it. It took a while to obtain, but worth it in the end," Robert concluded. Robert's RX-7 is more than just epic. It has a laundry list of rare parts and modifications that put it up there with the great FD3S builds in history. But we also gotta give him props because he created a car of this caliber without the help of a big name shop but with five years of patience, passion and dedication to accomplish what he envisioned from day one.

Fantastic Four-Rotor

Just like how more cylinders usually lead to more power, in rotary land, more rotors can do the same. Mazda knows this, and proved it with the R26B-its most infamous quad-rotor mill ever that powered its early '90s Le Mans-winning 767 and 787B race cars, the first to do so without pistons and rods. Unlike piston-based engines where you're constrained by however many holes you're block's got, rotary engines' housings can, conceivably, be mated together, delivering you from, say, something like the FD3S RX-7's two-rotor 13B-REW to something like the Eunos Cosmos' three-rotor 20B-REW engine. Do it right and you've just increased displacement and the ability to make a whole lot more power. The process is every bit as complicated as you think it'd be, too, and, when it comes to assembling a quartet of rotors together, can eclipse the $50,000 mark real fast. That's because of things like the custom eccentric shaft that's got to be made that, like a crank does for its cylinders, passes through each rotor housing, allowing them to sync up with one another. But then there's that unmistakable sound and, all of a sudden, upward of $50K almost seems worth it.
