As a nation famed for its endurance, self-discipline, and peace of thoughts, the Japanese appear to have a behavior of restoring essentially the most unforgiving and uncompromised race vehicles to the highway.
Most likely essentially the most well-known – or most documented, at the very least – is Takeshi Moroi’s Porsche 962C featured by Dino again in 2012. Many years earlier, this might’ve been thundering down the Mulsanne Straight at over 200mph. Nevertheless, seeing it parked in entrance of a Tokyo Household Mart is someway much more spectacular.

In case you desire your race vehicles extra suited to something however clean tarmac, Junya Matsushita’s S4 Subaru Impreza is the epitome of ’90s WRC. Constructed by Prodrive for the 1998 season and imported from the Netherlands in 2010, Junya spent years painstakingly restoring it to its former glory. Costly, however price each penny.

And for these with out the funds to sink right into a legit ex-racer, all hope just isn’t misplaced. Merely ditch all of your automobile’s comforts and spend a terrifying period of time sourcing period-correct components like wheels and spoilers, and the result’s your very personal road-going duplicate. A ardour shared by Mashahiko Yamazai and his pals as they rip across the streets of Saitama of their Tremendous Touring-inspired builds.

Race vehicles will all the time be cool. That’s a press release each Speedhunter will be united on, and their attraction for being transformed from observe to highway use nearly all the time comes again to the identical motive: to create the rawest, most unfiltered and visceral driving expertise possible… with out having to go to the observe first.

Is that this all the time pleasing? Completely not. The fact of proudly owning a real race automobile for the highway – versus a highway automobile tweaked for the racetrack – generally is a lot extra painful. And I say that as somebody who owned a road-going Ferrari 360 Problem automobile for practically 5 years, which subsequently spent lower than 12 months really match to be used.

However now and again, one thing so unhinged comes alongside that surprises even essentially the most seasoned Speedhunter, one thing so obscure and ridiculous it goes past the how is it on the highway and firmly into the why. As a result of within the sport of road-legal race automobile High Trumps, Syuichi Kinoshita has an nearly unbeatable hand…


The Lamborghini Diablo wasn’t precisely in need of a particular version. Between 1990 and 2001, a complete of two,907 had been produced in Sant’Agata, with 18 completely different variations accessible over that point. The majority of these (873) had been 2WD Diablos between 1990 and 1996, adopted by the VT and VT Roadster (together with the later 6.0 in 2000/2001), which between them account for nearly two-thirds of Diablos produced.

Delving into the extra restricted fashions, the SE30 accounts for simply 157 items, adopted by the GT with simply 81 being constructed between 1999 and 2000. Then, there are the 2 racing editions – the SV-R and GTR – restricted to 30 items every and completely constructed for racing. Though, in line with Instagram, most of those now seem like road-legal and residing in Japan, too…

Nevertheless, all of those numbers look positively mass-produced in comparison with what’s tucked away in Kinoshita-san’s storage. Not solely is it considered one of two REITER Engineering-prepared Diablos constructed for competitors within the GT2 racing class, nevertheless it’s additionally the one one which’s road-legal. And that wasn’t a requirement for competitors use or REITER feeling significantly spicy; that’s all on Kinoshita-san who, after acquiring the automobile in a fairly dangerous state, determined he would possibly as properly throw within the further bits wanted to get it authorized for its shaken (roadworthiness) inspection whereas reassembling it.

“A good friend of mine spent practically three years monitoring down and acquiring the automobile, however as soon as it arrived, the dimensions of labor required was an excessive amount of for him to deal with,” Kinoshita-san explains. “On the time, I already owned a Gallardo LP560, so I understood the attraction and theatre of a Lamborghini. It could take a very long time to rebuild and reassemble the REITER GT2 Diablo – round 10 years in whole – and lately, the components are nearly inconceivable to seek out. And for the components you may get hold of, values have skyrocketed!”

REITER was shaped in 2000 by racing engineer Hans Reiter, and the GT2 Lamborghini Diablo can be the primary official REITER-prepared automobile to compete within the FIA GT championship. Taking the already potent Diablo GT as a base, REITER extensively modified each vehicles to satisfy the GT2 laws, with the 6.0-litre V12 engine producing practically 600hp.

This GT2 Diablo would mark the start of REITER’s Lamborghini journey, as for the subsequent 14 years, they’d be accountable for growing and making ready all of Lamborghini’s race editions, together with the Gallardo GT3 and the brutal Murciélago R-GT.

“I’ve all the time cherished vehicles from a younger age, and as quickly as I might drive, I’d take pleasure in modifying no matter I owned to make it really feel extra like a race automobile on the road,” Kinoshita-san recollects. “At first, I began with an EP71 Starlet, then a JZX90 Mark II and even a GX71 Cresta. I purchased my first Lamborghini – the Gallardo LP560 – afterward as a result of I cherished how tough, highly effective and engaging it appeared. It had the seems to be and efficiency of a racing automobile, nevertheless it was nonetheless very simple to make use of on the road. Rapidly, I grew to become obsessive about all issues Lamborghini, and when the chance got here to purchase the REITER GT2, I couldn’t say no.”

With solely two vehicles in existence, the principle problem Kinoshita-san confronted was attempting to exchange any lacking or broken parts – lots of which required custom-making and took months to reach. Fortunately, the 6.0-litre V12 and Holinger sequential gearbox had been nonetheless in good situation, and regardless of its racing historical past, the all-carbon exterior was full, together with the GT2-specific parts such because the diffuser, rear adjustable wing and entrance splitter. Kinoshita-san knew early on that he wished to get the GT2 road-ready, so throughout this course of, he took a number of measures to attempt to make it just a little simpler to take care of sooner or later.


“In racing kind, there are not any exhaust restrictors, so it’s loopy loud!” he provides. “I put in a number of silencers and an exhaust valve to maintain the Diablo quiet at low velocity, which I feel my neighbours had been very glad about. For racing, the gas tanks are a bag in a Kevlar case, however these expire each few years and are very costly to exchange. So, we created an aluminium tank as a substitute, and on the identical time added a entrance nose-lift system; in any other case, it might be too low to drive into most gasoline stations.”

“The one factor I’d nonetheless like to vary is the steering rack as a result of attempting to get round Japan’s tight roads takes many makes an attempt, however it’s a small value to pay to get to make use of such a loopy automobile on the highway.”

Watching Kinoshita-san thread the Diablo by Tokyo is nothing in need of jaw-dropping. Aside from the warmth – which Kinoshita-san has tried to fight with a token 12V fan within the footwell – it’s surprisingly well-mannered and unusually quiet. Till the exhaust valve flicks open…

The smallest quantity of throttle will simply mild up the 310-wide Michelins. Don’t be fooled by the grooves; these aren’t typical Pilot Sports activities or Cup 2s; they’re a full wet-weather competitors slick as a substitute. However with indicators, quantity plates and the flexibility to crawl over velocity bumps, it’s match for the highway… nearly. And Kinoshita-san doesn’t cover it away both; he’ll usually be a part of Lamborghini proprietor days at any alternative. Whereas its lack of observe use would possibly look like a waste, earlier than he took on the challenge, it was simply one other ex-race automobile in a thousand items unfit for any use.

“Along with the Diablo GT2, I changed my Gallardo with an Aventador, which is a totally completely different expertise,” provides Kinoshito-san. “The mixture of the Lamborghini look and a naturally aspirated V12 is one thing I feel many people dream of. They’re two fully completely different vehicles, however additionally they share lots of the identical DNA, which I feel will be present in all Lamborghinis, new and outdated. However what I wish to do greater than something in 2025 is to take the GT2 again on the racing observe to see the way it performs. It will not be as quick as fashionable race vehicles, however I don’t assume there are a lot of different vehicles on the market which can present the identical sort of feeling – and that feeling I’ll by no means get tired of.”

You’d assume that after a road-legal 926C, a WRC Impreza and a GT2 Diablo, the streets of Tokyo couldn’t get extra outrageous. However Kinoshito-san is already eyeing up the subsequent REITER challenge – a Murciélago R-GT. In relation to Japan, you by no means rule something out.
