Speedhunters visited Ross at AVO Japan and did a great job:


It was a couple of weeks back that I got an e-mail from Paul Hansen over at AVO America. He let me know that Ross at AVO Japan would be collaborating on a very special new D1 Grand Prix built together with the guys fromDroo-P. I instantly knew what he was talking about, it could have only been Hibino's Toyota 86 which will be replacing his old and trusty AE86 starting from next month at the first Round of the 2012 season in Odaiba. Ross told me the car would be sent up to his workshop once Droo-P down in Okayama would be done with the chassis prep, ready to accept one crazy EJ25 motor!

Up Garage, the Japanese second hand car parts chain store that has been providing good deals to car enthusiasts for years now, will continue to sponsor Hibino and his team, with Falken tire still on board for the season.

Once I got the OK from Ross that the car had arrived at his shop in Tokyo, I didn't waste any time. I wanted to see what this 86 looked like, after all it's not every day you get to check out a race car build of a model that isn't even on sale yet! Upon my arrival I found Ross busy at work, finishing up the intercooler piping....

...that would plumb the custom intercooler to the rest of the engine. AVO are of course Subaru specialist from Australia, but have now been active in Japan with their own shop for ten years. In that time they have established themselves as builders of some of the wildest Imprezas, like their own widebody time-attack GDB which was also in the workshop at the time of my visit getting a bunch of new stuff fitted. But more on that on a separate post. At the heart of Hibino's 86 is a top of the line Cosworth EJ25, boasting a capacity of 2.6L thanks to fully forged internals and prepped heads that are ready to take the abuse from some serious forced induction...

...which will be provided by this little blower. This custom made new AVO turbocharger boasts a 0.70 A/R compressor housing...

...all custom made internals and an anti-surge attachment which will soon be added around the intake.

The EJ's 2.6 liters will have no problem spooling up the compact turbine housing, which is actually made from stainless steel so it can take much higher temperatures and is far more resistant to warping. 

Here is the view from the back, where the front pipe and exhaust system still have to be completed.

Ross kindly allowed me to have a detailed look of the 86 from underneath, where all sorts of interesting things can be observed, starting from the shiny stainless steel exhaust manifold.

Since D1 cars spend the majority of their time travelling completely sideways at speed, Ross knew that he had to make sure the engine lubrication didn't suffer. So he got rid of the stock wet-sump and replaced it with a Cosworth dry-sump kit which consists of the main items you need for the conversion like the billet sump...

...the 2-stage scavenger pump, the pump's mounting bracket and the adaptor to drive the pump pulley off the crank. To this Ross had to add all the Earls fittings, braided lines...

...and of course an oil reservoir tank, a rather big one at that holding a massive 12L of the finest synthetic oil out there. 

Ross had just finished fabricating the billet fuel rails that supply the juice to the four 1000 cc/min injectors.

Koyo supplied the racing radiator, a custom part that even sported the above etched-on writing on it.

Ross fabricated this custom intercooler set up with special end tanks that direct the piping upwards rather than around the corners of the front of the 86. The idea behind this is that if Hibino has a minor collision, or clips another car during a tsuiso battle, there is less of a chance of bending or damaging the piping. This solution of course also keeps piping short, which is always good for throttle response. 

Another special part from Cosworth is the intake manifold, a larger volume item mated to a larger diameter mechanical throttle body.

These Bosh ignition coils were ready to be installed...

...along with the Link G4 ECU. The custom wiring loom and electrical system was being painstakingly created on the day of my visit too, but more on that in Part 2.

Ross will be loading the 86 with tons of sensors... 

...to data log as many parameters as possible in order to see how the engine, along with the rest of the ancillaries, behave under the stresses of drifting. 

With a target of 700 HP this EJ will need a nice and strong gearbox to transfer all that power efficiently. This won't be too much of a concern as the stock Toyota/Subaru transmission has been replaced...

...with a very compact Hollinger 6-speed sequential. 

While under the car, I also checked out the custom transmission mounts...

...and the subframe that was fabricated to hold the sequential in place. You can also see the rounded off section where the custom exhaust will pass through once completed.

Taking care of the damping is an adjustable DG-5 suspension kit, which will no doubt require some fine-tuning once the car is finished and Hibino has a chance to drift it on track for the first time.

Project µ supplied the brakes with 4-pot calipers and 2-piece slotted rotors at the front. You can also see the hub extender which kind of hints that the car may be fitted with wider fenders, but I guess we won't find out if this is the case until the first round in Odaiba next month.

In Part 2 we'll take a look at the rest of the car starting from the interior, which as you can see above has been fitted with a custom welded-in roll cage and a ton of other nice little gadgets. More on this Toyota 86 build soon!

Part 2 of Speedhunters visit:

It's time to finish up taking a look at what has so far been the most extreme Toyota 86 build we have come across, and again many thanks have to go to Ross at AVO Japan, Paul at AVO America, Droo-P, Up Garage and all the other companies involved in the build of Hibino's 2012 D1 car. 

You can see that the car is still wearing the Falken livery that was quickly done back in January when it was, in stock form, driven at the D1 Exhibition during the Tokyo Auto Salon. The body, along with probably the coloring, might change but we won't find out until next month...

...so let's concentrate on the more evident details starting off inside. Like we saw in Part 1 the interior has been completely stripped out and modified in specific areas like the transmission tunnel, boxed out in order to fit the Hollinger sequential.

A custom linkage has been made for the shifter seeing the racing gearbox is far shorter and more compact than the stock unit. This of course also called for a modified propeller shaft but more on that further down. 

Here is a detail of the custom roll cage, gussets welded on to the B-pillars. Some of you noticed how the construction of the roll-cage differs to some of the more complex cages that are built in drift or race cars abroad. D1 doesn't specify any guidelines to roll-cage construction so it's up to the tuner to fabricate what he sees as the best cage for the application.

The AVO guys were also busy at work on the dashboard, which was removed to make it easier to fabricate the custom switch panel for the center console...

...and the carbon fiber backing plate onto which the Link LCD dash unit and data logger would be fitted onto.

There you go, perfect fit!

These are the braided fuel lines that pop out through the bulkhead...

...pass along the transmission tunnel, under the Tilton brake bias adjuster...

...and right into the trunk. As you can see above, the stock fuel tank has been retained, with two upgraded in-tank fuel pumps sending the high-octane juice...

...to the collector tank in the trunk. The fuel is cooled through a little radiator...

...as well as this bucket-type cooler which is filled with ice, or even dry ice.

The big Optima Yellow Top battery has been fitted centrally in the back of the 86, where the stock rear seats would be.

With most work almost complete it was the custom wiring loom that needed to be fitted and laid out around the chassis next.

This is the mess of wires that are needed to make everything work, all measured and cut to just the right length and grouped together as required.

It's a tedious job and one that calls for years of experience, not to mention lots of patience, which is why...

...John Marsh, or "Crazy Gaijin" as some Japanese started calling him during his time here, from AVO Australia flew up to Japan to take care of it all. He is a specialist in this field and was casually chatting to me while neatly organizing tiny wires together. Crazy stuff!

Here is the almost completed loom! 

While I was buzzing around the workshop shooting pix of the 86 and AVO's GDB, Ross had shortened one piece of intercooler piping and was welding on an aluminum plate onto which temperature and pressure sensors would be fitted.

Thankfully there was still a bit of snow left in front of the shop from a few days before which proved to be perfect for cooling the pipe down after welding. 

It was then on to drilling up three holes on the plate and threading them, ready to accept the sensors. With all of the tools and machines that AVO have at their fingertips this was all done in the space of ten minutes! 

Let's move on and take a look under the rear of the 86. The rear subframe...

...and stock differential housing remain, but have been joined by a lot of other upgrades beginning first with the modified propshaft, and a Cusco 2 Way LSD.

Again from Cusco are the adjustable pillow ball lower arms and traction rods.

Here is a view of one of the rear DG-5 dampers, along with the Swift main spring and smaller helper spring. You can also spot the orange AVO polyurethane stabilizer bush deep inside the lower arm.

Another look at the Cusco parts. Cusco will have a complete lineup of parts available for the Toyota 86 and BRZ available from later on this month so those lucky enough to get their hands on one of these cars will be spoiled for choice from the get go on upgrade parts!

AVO fitted their rear stabilizer reinforcement brackets, a mod I've been wanting to make to my Legacy for a while now. Like on Subarus, the 86's stabilizer mount is made from thin steel plating which bends under stress, throwing off the full effect of the stabilizer bar. This steel plate helps keep things nice and firm, giving a better feel from the rear end, improving things like mid-corner adjustability and turn in. 

Like up front, rear braking is handled by Project µ calipers, small 2-pots biting down on larger diameter slotted discs. Last night Ross had the car on the Dynapack hub dynamometer at AVO and did an initial set up of the engine to make things everything was working as it should. The car is on the way back down to Okayama now where the body part of the project will be addressed along with smaller things. Before the car left AVO last night Ross grabbed a shot of the completed engine bay...


...not bad right? And to answer some of the questions from Part 1 as to why the Cosworth intake plenum hasn't been rotated 180º, the reason is simple. Ross wanted to do this to keep piping shorter and more direct but this can't be done due to the positioning of the mounting bracket of the Cosworth dry-sump oil pump which is right in the way.  

I can't wait to see this thing in action through the tight Odaiba course next month! Don't forget this will be one of three Toyota 86 D1 cars; HKS are busy at work preparing Nob's machine ready for his return into the series and of course there is Orido's 86, powered by the Lexus ISF's 5L V8, which is in the final stages of the build. These cars will no doubt inject much needed excitement into the D1 Grand Prix, which has been struggling for years to attract the same big numbers of spectators it used to during its heyday.
