Just like the modified automobile scene, magic is at all times evolving. From the times of prime hat sporting conjurers utilizing their white-tipped wands to materialise scantily-clad girls from seemingly empty bins – or white tigers to sink their enamel into their associate’s neck – over time magic has became one thing very totally different. The likes of US-based illusionist David Blaine, or the UK’s very personal magic man Dynamo, have taken the artwork of magic to a spot that doesn’t revolve round smoke and mirrors or elaborate stage exhibits, they’ve taken it again to wowing folks close-up, with new and unbelievable methods that take inspiration from the legendary magicians of the previous, but place a complete new twist on them. And modifying additionally continues to evolve. Traits come and go, however the true icons stay, simply with slightly trendy twist, as US-based rotary fan Jonny Grunwald’s tuned RX-7 FD proves.

“I’ve at all times favored to do issues otherwise,” says the Lengthy Seaside-based entrepreneur.

“The truth that the rotary powerplant wasn’t your typical engine, and even that the RX-7 wasn’t your typical automobile, was what appealed to me within the first place. On the time, I used to be solely simply moving into the Japanese tuning scene, and Evos and STIs had been the preferred vehicles on the market. However as ordinary, I wished to be totally different from everyone else.”

And Jonny’s distinctive lifestyle has additionally prolonged to the way in which he has tuned his automobile.

“In terms of vehicles, I’ve by no means been one to fret about following the most recent tendencies or the present Web hype,” Jonny shrugs. “I constructed my automobile the way in which I wished it to be, to not attraction to social media.”

But, though he has shunned the style for bolt-on arches and over-wide wheels and tyre setups, his mighty Mazda is undoubtedly a neck-snapping head-turner.

“I drew inspiration from the enduring tuning homes of Japan,” Jonny explains. “The best way the most effective Japanese vehicles are dripping in uncommon, high-quality manufacturers which might be onerous to search out is what excites me. My expertise from visiting the Tokyo Auto Salon motivated me to not lower corners, however push the boundaries of my automobile so far as attainable. They construct full vehicles, which means each facet of the automobile is modified or tuned. I wished to do one thing related with the RX-7 and construct it in a means that may make even Japan’s prime tuners proud.”

And simply casting a watch over Jonny’s gorgeous tuned RX-7 FD, exquisitely-wrapped in 3M Satin Good Blue vinyl wrap, it’s clear to see that he’s achieved his purpose. From the flawless set up of the uncommon TCP Magic carbon-fibre wide-body conversion to the purposeful function-over-form fitment of the equally unique 18in Volk Racing VR21C wheels, this automobile screams high quality, and it’s removed from simply skin-deep.

“There’s a development for FD homeowners to swap out the 13B engine for a 2JZ or LS V8,” Jonny says, “however I used to be eager to retain the rotary powerplant. I do know they’ve a status for being unreliable – in actual fact I’ve gone via three engines already with this automobile and am now on my fourth – however I simply love them. The response you get and the way in which they rev to eight,000rpm, the sound and really feel are distinctive and it simply calls to me. In case your engine is ported and constructed correctly, like this one is, they will rev all the way in which as much as 10,000rpm!”

Jonny’s screaming 13B has been handled to a Fortunate 7 Racing half bridge-port with E&J 2mm apex seals together with a GReddy V-mount intercooler and radiator setup to maximise cooling. Customized pipework to and from the intercooler constituted of carbon-fibre is a neat contact that not solely seems cool, but additionally retains the consumption cost cool too, resulting from carbon-fibre’s innate warmth shielding properties.

Supplying the heady air and gasoline combine to the wankel-engine’s chambers is a Turblown 9180 EFR turbocharger and large 2200cc Injector Dynamics main and secondary injectors, these mix with a 4in HKS Racing titanium exhaust to supply an immense 700bhp of tyre-torturing twist.

“The best way it pulls when the turbo comes on increase is insane!” Jonny grins. “And the sound it makes while you maintain every gear till the ten,000rpm redline is really addictive. Fortunately, I’ve uprated the automobile’s transmission to deal with the additional energy.”

Transmitting the mammoth energy to the rear Toyo R888 tyres is a Spec Mini twin-plate carbon clutch and light-weight aluminum flywheel. This then forwards the grunt on to a KAAZ Tremendous Q 1.5-way limited-slip differential with 4.44 ultimate drive ratio, which supplies Jonny glorious grip ranges when he desires it, and easy tyre-shredding capabilities when he doesn’t.

True to his phrase of leaving no space untouched, Jonny has additionally uprated the RX-7’s suspension and braking capabilities according to the prodigious energy output.

“There’s a set of Stance three-way coilovers with exterior reservoirs beneath the broad arches,” Jonny factors out. “They’re customized valved and matched to a set of Swift springs to attain the most effective dealing with.”

The automobile’s braking system has additionally been handled to the most effective parts that cash can purchase with a bespoke setup by Brembo Racing Division.

“Brembo factored-in the automobile’s particular downforce figures, aero numbers, and power-to-weight ratios to construct a brake package that’s precisely tailor-made to the RX-7,” Jonny explains. “The package they got here up with options large 355mm superior high-carbon alloy endurance racing discs with four-piston monoblock calipers.

And this mixture of unique high-end elements working in excellent concord to supply a well-rounded consequence continues within the automobile’s cockpit too, with light-weight carbon-fibre and opulent alcantara combining to create a real supercar really feel.

“The carbon elements within the inside are there to enrich the carbon-fibre bodykit,” Jonny highlights. “Some had been customized made, just like the rear seat delete panel, whereas others are off the shelf, just like the doorways skins from Evo-R Motorsports. Being cocooned in carbon, whereas sitting within the luxurious alcantara-trimmed Recaro Profi SPG bucket seats actually provides you the sensation of being in one thing high-end like a Pagani or McLaren.”

However there’s one piece of the inside puzzle that Jonny reveres over all the remaining, and that’s the Private racing steering wheel with its blue hand-grips.

“It’s really a Prime Secret steering wheel from tuning legend Smokey Nagata,” laughs Jonny. “It has an ideal historical past behind it and has been within the arms of a real JDM icon, so I really feel like it’s nicely worthy of a spot on my automobile too.”

Trying over Jonny’s mind-blowing tuned RX-7 FD, you’d be forgiven for pondering that he’s owned a string of excessive efficiency builds earlier than, however in actuality, you couldn’t be farther from the reality.

“That is the primary automobile I ever owned,” Jonny admits with a smile. “It’s my child. You would supply me one million {dollars} for it and I wouldn’t promote it. It’s been via a lot with me over time.”

So, if that is the primary automobile he ever owned, how on earth did Jonny get the talents and data to construct such a masterful machine?

“I used to work as a venture supervisor for Los Angeles-based tuning agency Bulletproof Automotive.” Jonny explains. “My first venture for the corporate was the ‘Idea One’ Scion FR-S, (Toyota GT86) in 2014, which traveled internationally to Japan. I then managed each automobile construct from the Idea One till SEMA 2015. All the pieces from engine specs to inside, exterior, disassembling the vehicles, and placing them again collectively was beneath my spectrum of duties. It was an ideal expertise being with the corporate and I used to be uncovered to all of the high-end manufacturers that I’ve grown to admire and respect immediately.”

Jonny might have acquired his tuning nouse and a bulging contacts guide from his time at Bulletproof, however even after leaving the corporate, his ardour for Japanese vehicles remains to be simply as robust.

“It’s been wonderful seeing the scene evolve over time,” he enthuses. “From once I first obtained into it 15-20-years in the past, when it was all neon lights and Sizzling Import Nights, to more moderen occasions the place the main target has shifted to extra excessive engine builds with vehicles making nicely into 4 figures – it’s actually insane!”

So whether or not it’s the present tendencies doing the rounds on social media, or the exploits of Japan’s prime tuners, the important thing to constructing a ground-breaking journey is to not merely comply with the herd, however to make use of no matter conjures up you to forge your individual path to greatness. And that’s precisely what Jonny has finished together with his tuned RX-7 FD. By constructing a whole machine and specializing in the small print, he wants no smoke and mirrors to achieve a status as among the finest within the enterprise, as his automobile does the trick for him.
