"Option Magazine came to our Japan office to film the starting up of Hibino's Droo-P FT86. Thanks to a marathon effort by Ross, Esumi, and the rest of the AVO Japan crew, they got the car running for the first time yesterday! — with Norio Esumi and Ross Wilson."

SHES ALIVE! IT LIVES IT LIVES!

We didn't do the rollcage, it came to us that way. So cannot really comment on *why* they did it that way.

>Oil tank location: I'll ask, but I've a feeling it's a combination of finding space available vs. time vs. the fact that they are probably putting the passenger seat in and taking passengers around in the car. D1 in Japan isn't quite the same as FD in America, and a lot of "street" is left in for various reasons.
It also could be it was simply there temporarily while they got the engine running and started tuning. We were asked to build the engine, turbo, and get it tuned. A lot of the final details will be done at Droo-P's own shop.

>flipping the manifold: I'm not sure. Space reasons, probably. It's not an Impreza, but we are shoe-horning a motor for that chassis in. It could be as simple as the fact they'd have to put a bump in the hood to accommodate rotating the manifold, and I don't think they want to do that for a lot of reasons.
Besides, with proper tuning (which isn't seen all that often) the minimal difference in volume the "extra" piping won't even be felt, *especially* at the track. With a small turbo on a "street" build, flipping the manifold has benefits, but on a 600-700hp track build where the driver's foot is flat to the floor most of the time - not that much.

> Hollinger: I'm pretty sure that particular application is for RWD only. I'm also sure Hollinger makes a version for AWD cars.

>Safety Regulations: Well... it's not America. When I was shooting D1 cars back in the day, there were times where my only protection from the car drifting about 5 feet from me was a safety cone. That's just the way they roll.

Part 2!

BUILD>>
HIBINO'S D1 TOYOTA 86 PT.2
Filed under: Toyota, Japan, Droo-P, Dino Dalle Carbonare, Hibino, 86, Builds 2012, D1-GP, AVO Turboworld

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.

[aesthetect]

any chance at more details regarding how much modification was required for the engine crossmember??

[AVOturboworld]

I'll ask - it wasn't that drastic. But it's definite that the engine bay was not designed for a turbo setup, the space underneath is quite tight as well.

Keep in mind that, when it comes to these engine swaps for the race cars, we have the luxury of pulling every bit and piece inside the engine bay and rewiring it all for the fitment. Putting a EJ25 into a production engine bay is going to be far more difficult.

meh, im plenty excited about the 2.0 NA, just hope it responds decently to some basic modifications ..and is able to take a beating

[AVOturboworld]

We'll be finding out, we've just gotten our BRZ in Black this week!

Of course, after we figure out the N/A parts, we'll be right into the forced injection with it...

I'm assuming you've got a BRZ in Japan, not here in Seattle?

If you have one in seattle...

Let me come look

[AVOturboworld]

Japan! If I had one here this early in Seattle, well, I wouldn't be able to talk about it or show it anyways. I can guess where one *might* be, but I'm no longer allowed access to that lot.
