Nascar Power: The Rs-r Formula D Asia 86

When faced with the need to stand out, a true challenge in any forms of motorsports, it’s pretty safe to say that RS-R have taken the correct path. With a need to replace their successful, yet ageing JZA80 Supra, for this year’s Formula D Asia championship, they ended up doing things a little differently. It was decided early on that the ZN6 would be the perfect choice for this whole new project…

…but the true dilemma came when they began brainstorming ideas for the powertrain. What RS-R and Flatwell have achieved with the 2JZ is nothing short of impressive, building upon the straight-six’s capabilities and reliability extremely well, extracting superb levels of performance that kept them competitive in the various drift series they entered their Supra in. However, while the “2J” would have been a great choice, it would also have been – how can we put it – predictable. So, what did they do? They took the complete opposite path and in the process challenged both themselves as well as their drivers. The result is the car you see here, well a 95% finished interpretation of it at least. So if you focus beyond the “in-progress” looks your will find what has to be the most complex drift-oriented Toyota 86 anyone has so far created…

…boasting a TRD NASCAR V8 swap. Now for all you Formula D fans out there, seeing V8 transplants must be pretty normal but you need to understand how uncommon this is in Japan. This is the first time RS-R have attempted anything like this and the result is simply mouthwateringly impressive.

Plus, seeing those TRD head covers in a Toyota chassis, well it just looks so right doesn’t it! The V8 motor was sourced from the US and originally came from Ed Pink Racing Engines (EPRE) in California.

EPRE converted it to fuel injection by welding in eight injector ports on the existing inlet manifold, fed by a pair of Wilson Manifolds fuel rails.

An LS-series electric throttle was then added along with the top mounted 90-degree elbow, the whole assembly along with Blitz mesh filter sticking right through the hood, something that will become the car’s most recognizable feature, especially after Kei Miura of TRA Kyoto completes the hood scoop that will cover it all. But more on that later on.

Ignition is handled again by a direct coil system borrowed from an LS engine, replacing the distributor that was run originally.

The engine already came with billet aluminum anchor points, so what Flatwell had to do (the shop that was commissioned to build the 86) is machine some mounts and position the whole unit properly in the vast engine bay. And I say vast because there is plenty of clearance all around the engine, one of the benefits of designing a car around a boxer motor. The 86 really is made for swaps!

The stainless steel headers have individual temperature sensors for each cylinder, one of the many parameters that are logged via the Motec engine management system. In this way the best possible performance can be extracted safely from the engine at all rpm, as the ECU continuously monitors and adapts to even the smallest variation of temperature, A/F ratio and knock. This allows both drivers of the car, Manabu Orido and Fredric Aasbø to make full use of the close to 750 HP the motor churns out without many concerns. This is precisely why RS-R went for this set-up, the NASCAR engine offering the best of everything – ample power and torque, simplicity and reliability. All they had to do it drop it into the compact ZN6 chassis and set it all up for its new dorisha duty!

Lubrication is dry-sump of course but for best weight distribution the oil tank, as you will see further down, is located in the trunk and feeds the scavenger pumps up front via very long and very large diameter braided lines. Big engine big everything else – including the truck sized Fram oil filter.

We were invited to check out the car’s first shakedown test in Suzuka Twin the other week, where both Orido and Fredric worked hard with the team to iron out little problems and get everything working properly. You will be finding out all about that from Fredric’s own blog soon, but needless to say it was impressive seeing the RS-R guys at work once again, fine tuning an all new machine and make it perform so damn well in such short time! But enough of that, let’s get back to the car itself! As you have probably already noticed the exterior of the 86 has been pumped up with a full 6666 Customs Rocket Bunny aero, the same that is used on Fredric’s own car back in Norway. Kei Miura will be adding some custom touches like the hood scoop and a custom rear diffuser section, but the most important additions to the car itself –  from a performance point of view – were the front and rear overfenders. These allow the Enkei wheels to be pushed right out to increase front & rear track and give tons of space for aggressive negative camber, as well as toe and caster adjustments.

Behind the front RP03 hides a Project µ brake upgrade with big 6-pot calipers and 2-piece slotted discs, 4-pots at the back Also take a look at the spacers that have been added to further increase track and play around with geometry on the test day.

To appreciate the car you have to look beyond its unfinished, multi-colored exterior. The stock red doors are to be replaced with lightweight dry carbon items to slash a good 20+ kg from the body and the whole car will be painted white before the trademark RS-R graphics are applied.

There isn’t much bumper left, everything has been cut away to expose the underpinnings of the custom rear treatment. The tubular section is there to hold the custom cooling set up in place…

…as well as to offer an anchor point for the megaphone titanium exhaust. Actually it shouldn’t even be called an exhaust but a screamer pipe, from where thunder is released when Fredric or Orido give the slightest prod to the throttle. Never has anyone heard a V8 scream like this in Japan, that’s for sure!

Sending drive to the rear wheels is a Winters Performance quick change rear end that not only allows tons of adjustability for the various tracks in the Formula D Asia series, but great reliability…

…when pulling these sort of full-throttle-in-fourth-gear epic drift moves! The rest of the driveline is finished off with a Hollinger sequential transmission…

…further helping to annihilate lots of sets of Yokohama Advan Neova rubber!

Undo the two rear latches and the top quick release pins and the featherweight carbon trunk lid is easily lifted off the car…

…revealing this work of art. It may look extremely complex in there but the need to balance the weight efficiently in the car dictated the need to shift components into the trunk.

The big tank is for the dry-sump lubrication and on top of holding 12 liters of top of the line synthetic oil, it’s also fitted with a warmer to get the oil up to temperature before it’s circulated into the engine.  The rest of the piping you see feeds the two L-shaped radiators that have been beautifully…

…positioned on each corner of the trunk area… Along with the engine’s water pump…

…an additional two electric pumps are added to help flow the coolant the extra distance.

It’s all topped off with this overflow tank.

To further help shave weight off the rear glass has been replaced with a lightweight lexan sheet while the roof has been hacked off and a dry carbon one fitted in its place. The attention to detail truly is mind boggling.

This rough cover placed over the lateral rear windows is a piece custom made by Nakawatase-san, Kei Miura’s newest employee and known for his crazy military themed Volklinger S14 Silvia. Once cut out it will help channel even more air towards the rear radiators and give another bespoke touch to the car’s exterior.

Open the soon to be replaced stock doors…

…and your first sight is the highly bolstered Bride racing seat, where Fredric and Orido will do their thing.

This Nardi steering wheel is what Orido used during the test days, with Fredric preferring a deeper cupped Tanida item for a more “rally-style” driving position.

All engine parameters are displayed via the Motec SDL3 digital display dash unit…

…and if you peek behind the semi-stripped stock dash you can just about see the Motec M800 unit, the brains of the car.

I thought this was a neat way to take care of the switch panel, rather than lining up a bunch of old style toggle switches on the center console everything is cleanly  arranged in this easy to understand switch panel. The buttons are even rubberized so that you don’t slip while pressing them while wearing race gloves.

With Fredric being quite a bit taller than Orido, an adjustable pedal box was a must so that, just like in the Supra, both drivers can be easily accommodated.

One of the most important commands in a drift car is of course the handbrake (or e-brake/side-brake depending on what sort of English you speak). The level actuates the Wilwood hydraulic pump that instantly locks the rear wheels to initiate drifts or help the driver prolong them.

The rear section of the cabin is where the fuel system is laid out along with the aluminum water lines…

…and the beefy braided oil lines.

RS-R and Flatwell knew their new Formula D Asia car had to be special, but after spending some time looking over the 86 in detail at Suzuka Twin, not to mention observing two days of testing, we can safely say they have really outdone themselves in every way.

We were lucky enough to get some images minutes ago from the RS-R guys showing the almost completed look of the 86. The team were back out for one last test session in Okayama yesterday…

…with Orido, fine tuning the suspension set up before the car is sent off on its 9-month voyage around Asia. Needless to say we can’t wait to see Fredric rip up the track in Melbourne next month at the first round of the 2013 FDA season!

Very interesting build, definitely something different. That TRD motor looks the tits in that bay... I hope they will lower the rear though... Looks a bit weird from the front 3/4 angle.

@ToyotaPR Cheers for the namecheck! I won't mention the fact we tweeted virtually the same footage (slightly shorter) back in mid-Feb... ;-)

Great write-up on a tremendous effort! The spirit of the '86 is pretty exciting. Can't wait to get my own (BRZ or FR-S) and start tinkering!

Jeez I knew there would be some haters but come on lol. Its a competition car with a proven engine package in it. I'm not a big v8 fan but a Toyota NASCAR engine in an 86 is bad ass. And does anyone know what switch panel that is?

No desktop of the almost done 86? I'll need a desktop of it in completed state. :D

This 86 is just crazy!

Man all these post and so many haters... This car is a work of art in the function department, Japan never sees these kind of builds Im glad RSR is branching out and trying new things. If  it runs and sounds half as good as Tanners TC Ill be stoked. Hope it makes its way stateside.

Reserving judgement on its aesthetics until the body/paint is complete, I'm sure Mr. Miura will do an excellent job on it.Would love to see some video or sound clips of this thing, really interested to hear what it sounds like with that blast tube.

As far as a cool car, yeah, it's quite ok. But as far as making me want to purchase an FRS/GT86/BRZ, absolutely zero interest gained. I understand swapping the 20 year old KA out of the 240sx for a different motor, but I do not want to see a BRAND NEW CAR getting it's motor pulled, I want to see the OE motor pushed to the limit first. Also, I am tired of that body kit already, someone has to be making a less aggressive looking piece by now. I hate Mondays.

If Mike Tyson were a car, he'd be this car. Hood throttle body = facial tattoo and it looks like (and probably sounds like) it's ready to bite your ear off and eat your babies.

jeez they sure need a wider front bumper lol.looks horrible from the front.not a fan at all.. 1000's of builds, this one is aesthetically p*ss poor, especially for a professional drift car!

this ARC handbrake assembly is a piece of art!

Does anybody know if this is a one-off item or also sold to the public?

@Legon The most expensive sound system of whomever's watching this will not do that engine sound justice. I think everyone should hear a NASCAR V8/ DART big block  at full song, ideally amongst other big angry engines. Everyone at that track drivers included were probably thinking "THIS! This is how things should sound...all the times."



@the haters...to hate on one thing you may as well hate on every little advancement in drifting until you've stripped it all back to the mountain passes of Kyushu or elsewhere. You like your revised suspension geometry jewels on your 180sx? Wings? Cages for safety, turbo or jaydee mm engine swaps? I bet ya do. I'll also bet most of you motherf*&#ers didn't start out in those mountain passes. Likely an empty Costco parking lot. You don't hear the Japanese bitching about Aasbo coming from Norway.  We may not even be talking about drifting if those OG togue drifters didn't try to push the envelope. I've been a drift fan since '97 and I understand it can hurt when someone takes your special, secret little thing, shares it with everyone, changes it...


The beauty of a performance car is how well it can perform its given task, and obviously Speedhunters is about celebrating the craftsmanship in the individual journeys to that end. This car is a tool for showmanship (like all drifting)-the sound, the smoke, the angle and it does that job very well.

 @IshMel  dude soo true i can see why they took out the shitty boxer to i mean why have a toybaru when u can have a v8  tyre shreder stamped wiv TRD

 @IshMel Yup. all the haters got an opinion on this PROFESSIONAL DRIFT CAR (not a street car! Built to WIN!!) yet not a single one of any of these posters are A) a team owner that makes the $$ decision, B) a DRIVER of these cars. or C) competing in ANY professional drift series.

 

That means every single one of these people's opinions don't matter and aren't worth the pixels they are printed with. This car will be a  competitive monster, and THATS THE ONLY THING THAT MATTERS HERE.

 @DeleriousZ the body/paint is complete if you havent seen the finished product see dino's fb page or google it, and the front still looks the same...crazy to have a NASCAR powered gt86 competing in japan, but damn i still think that front is uuuugly.

LesBruce

yo u obliviously have never tryed to work a boxer motor they do not make big power and they go bang alot faster than a proper piston motor  and that v8 even in factory form will still out perform and subaru motor out to day weather its got a turbo or not.they have swaped to a v8 for its low end power so he can use more hand brake and less clutch.and i garantee that it will be alot more reliable wiv less maintance required after each drift day

 @r0taryh3ad  I doubt ARC Brazing made this. I think whoever made the pedal box also did this. they both have the same design traits.

 @D1RGE EXE  @IshMel So unless you are also, "A) a team owner that makes the $$ decision, B) a DRIVER of these cars. or C) competing in ANY professional drift series.", your opinion doesn't mean anything either, correct? So you are as worthless as the pixels you are 'displayed' on as well.

 @D1RGE EXE  @IshMel i bet most of the haters dont even no the first thing about how to drift a car i mean kickin it out around a roundabout or as u turn in or out of a street and shit these guys hit the corner in a straight line at 200k+ then turn and control the slide is drifting if u are sideways before the corner it counts if its halfway threw the corner its a slide..

 @LesBruce That really has nothing to do with what I said as I never said it wouldn't be competitive. I'm sorry I don't like it for personal reasons, I'm sure it will be fast though.

thank you very much for the hint, they are also currently on sale... just ordered one for my FD :) If it's good enough for mad mike, it's more then good enough for me ;) I've owned 2 K-Sport/D2 handbrakes and they are a piece of s***... I've bended both handles and the brake cylinder mounting box several times... ;)

so, finally, I've found it! :)

You were right! It's not from ARC ;)

 

The handbrake assembly and the pedal box are both from a company called Perpetually TONNKA, a company based in Malaysia...

the don't have a website but a facebook fanpage... I think I have to get in touch with this guys looks like a real good quality product :)
