After I heard that RE Amemiya was engaged on a 4-rotor Ferrari Testarossa as their primary showpiece for the 2021 Tokyo Auto Salon, my response was in all probability the identical as yours studying the headline above – pure shock shortly adopted up with huge dose of curiosity.

After seeing a couple of construct photographs on Possibility journal’s web site, my curiosity took me all the way in which to Ama-san’s store in Chiba final weekend.


Ken Amemiya, RE Amemiya founder Isami Amemiya’s son, stated I used to be one of many first to {photograph} the automobile, but in addition that it’s solely 85% full and nonetheless in prototype guise. This implies RE Amemiya nonetheless have a couple of jobs to full, together with getting the engine up and working. As soon as it’s transferring beneath its personal energy, the Ferrari-Mazda mash-up shall be stripped proper again down for paint after which reassembled.

However no matter its primer grey state and incompleteness, I simply had to see this wild creation with my very own eyes.


In my head this was means an excessive amount of of a cool venture, however one factor I didn’t depend on was the extent to which Ama-san had modified the bodywork. I in all probability ought to have although. This was – clearly – by no means going to be a Testarossa with a shock engine, however slightly a full RE Amemiya {custom} construct, as we’ve seen lots of over time.


The look of this factor is certain to divide opinion, however I don’t suppose Ama-san actually worries about that kind of factor. This can be a venture two years within the making thus far, as commissioned by a longtime RE Amemiya buyer who simply so occurred to have a Testarossa he was tired of. That’s a automobile many would contemplate it sacrilegious to even mildly modify, however the proprietor of this one would merely slightly have a very one-of-a-kind RE Amemiya creation in his storage.


It took me some time to digest the automobile at face worth. It’s a strange-looking machine to say the least, however there are tons of little particulars and also you definitely can’t deny it has presence.


I imply, when was the final time you noticed a Testarossa with a roof scoop?


This factor is thus far faraway from the automobile it began out life as, that the one visible cue it’s primarily based upon one in all Ferrari’s most iconic fashions is the windscreen and door glass. This shot could emphasize that, but when not, squint slightly.


The legendary louvered aspect intakes have remained in spirit however have been given a very completely different look.


The entrance nonetheless is all new. Your entire part forward of the entrance struts was eliminated and changed with a {custom} body to help the cowl and different ancillaries. In comparison with a inventory Testarossa, the entrance overhang has been shortened considerably.

Like all RE Amemiya builds, the automobile wears a set of Enkei wheels – on this case 19-inch PF05s – wrapped in Yokohama Advan Sport tires. In the meantime, the brake system now options fashionable StopTech calipers and 2-piece rotors.


Many of the work has taken place on the rear finish, the place the chassis was minimize on the firewall and a {custom} part created to help the brand new engine and gearbox combo. Due to the size of the 4-rotor engine and the transmission behind it, the wheelbase needed to be prolonged, which makes the rear of the automobile extraordinarily lengthy. It type has a McLaren Speedtail look about it, and virtually a hypercar really feel.


The necessity to stretch the rear turns into apparent when you pop the engine hood.

By Mazda rotary requirements a four-rotor is a big engine, however within the Testarossa it’s much more compact and far lighter than the cumbersome flat-12 it replaces. It sits as little as it will possibly go and is straddled by a pair of Belief TD06 externally gated turbos.


These feed right into a {custom} top-mount intercooler, which is shrouded by and fed air by way of the roof scoop. The cooled and compressed cost is then distributed to every of the 4 rotors by way of a custom-made consumption manifold.

In essence, this engine is similar as the unit in RE Amemiya’s D1 FD3S RX-7, however is geared to have a broader unfold of torque. As soon as arrange and dialled in by way of the Hyperlink engine administration system, the four-rotor ought to develop 800 to 850hp.


Behind it, and getting used as a transaxle to drive the rear wheels, is a beefed-up Subaru 5-speed transmission.


It’s a very properly laid out driveline which ought to offered balanced weight distribution. The rear finish has a dramatic cut-out really feel about it; it form of appears to be like like an LMP automobile, proudly exhibiting all its guts by way of the carbon bodywork and copious use of grilles.


It’s from right here that the Energy Craft exhaust and screamer pipes sprout.


What does this rotary-powered Ferrari seem like inside?


Earlier than we get there, you must take a look at the Ferrari brand etched onto the door’s glass.


The inside has been modernized by way of quite a few {custom} touches, beginning with an AiM digital show neatly recessed into the instrument binnacle, and the Alpine navigation/multimedia 2DIN unit recessed into the middle of the now leather-clad dashboard. With the intention to mount the display screen, two louvered heart vents needed to be eradicated, that means that the one in-cabin air shall be provided by way of the spherical aspect air vents.


Customized Alcantara-trimmed Bride reclinable seats full the RE Amemiya conversion.


Our closing cease is beneath the single-piece entrance cowl. Very similar to the remainder of the bodywork, this panel is made out of moist carbon fiber, with Kevlar added in high-impact areas.


Right here’s a view of the custom-made Aragosta dampers with Swift springs, and the yet-to-be-plumbed-up flat-mounted radiator, which is able to hold the screaming, boosted rotary engine out again cool.


You’ve got at hand it to Ama-san for taking up a venture like this, which when accomplished shall be added to a protracted listing of {custom} autos constructed to coincide with the annual Tokyo Auto Salon. The Testarossa joins non-Mazda-based RE Amemiya builds like his Lotus Europa and the Westfield ‘Furin Kazan’, which I shot 11 years in the past now.


Of all his builds although, this one will actually have folks speaking. However regardless of the bottom automobile, Ama-san has approached this construct in precisely the identical means he’s approached his previous tasks, with a complete aesthetic transformation and a few form of rotary engine swap. If this was his objective, he’s definitely achieved it. It’s the Ferrari Testarossa half that some folks could not digest so simply.

I’ve had my say, so now let’s hear your ideas about this construct within the feedback part under…
