In the event you solid your minds again to 2021, you would possibly bear in mind my go to to Daddy Motor Works in Aichi, the place Kunihiro Oto first confirmed us his newest challenge automobile.
That go to stuffed me – and plenty of of you – with quite a lot of pleasure. The GR Yaris was just about model new, and right here was a man already swapping its three-cylinder turbo G16E-GTS engine into Toyota’s iconic ’80s AE86 chassis.
Within the time since, we’ve seen the automobile a number of instances at occasions together with the Tokyo Auto Salon and Nostalgic 2Days in its semi-completed state. Now that it’s primarily completed, I believed I’d head again over to Oto-san‘s store and spend a number of hours checking the Levin out intimately.
Contemplating this construct has very a lot been a facet challenge for Oto-san, it’s fairly loopy how briskly it has all come collectively. He has solely labored on it when he’s not been engaged on (paying) buyer automobiles at Daddy Motor Works, and there are at all times loads of these.
The superb response the challenge has obtained each in individual at occasions in Japan and worldwide over the web throughout the course of the construct has actually helped. Oto-san says it has given him the boosts of vitality wanted to maintain at it, and all of the automobile wants now’s some fine-tuning earlier than being shaken down on monitor.
Regardless of the lengths gone to and the eye to element with the construct, you is likely to be stunned to be taught that that is really a drift follow automobile for Oto-san. Proper from the outset he had no intention of going loopy with it, and the price range has been saved in examine proper all through the method.
Primarily, Oto-san needs to have the ability to replicate the construct in its core kind in an economical means for any of his purchasers.
The outside wears a generic AE86 entrance and rear overfender package, which needed to be modified and tailored to the inventory physique as the fiberglass was a bit wonky in locations. The matte silver paint and the delicate graphics give the automobile a contemporary look, whereas the polished lips on the Midori 2-piece wheels present some pop.
It’s most likely the engine bay particulars you’re itching to see although, so let’s head proper there…
As you’d count on, the Gazoo Racing G16E-GTS engine has been rotated 90-degrees counterclockwise from its inventory place within the GR Yaris to take a seat longitudinally within the AE86 – similar to the Hachiroku‘s authentic 4A-G. Being a three-cylinder not a 4 although, there was ample room to suit it, and you may see simply how far again it sits within the bay.
This ended up creating simply the correct amount of room wanted for a horizontally-mounted intercooler proper behind the radiator help. As soon as the air-to-air intercooler was mounted, all Oto-san needed to do was to determine a path for the piping.
He actually levelled up this facet of construct by stepping away from typical aluminum piping and hand-fabricating the consumption and outlet intercooler piping in titanium with pie cuts for a lobster tail impact.
The entrance bumper is connected through quick-release mounts, so Oto-san was capable of pop it off in 5 seconds flat to offer us a have a look at the remainder of the cooling setup. The intercooler, radiator and centrally-mounted oil cooler all obtain cool airflow from customized aluminum guides.
Rotating the engine meant the inventory and fairly complicated consumption manifold was not going to work within the AE86. From a visible standpoint this was factor, as a result of the customized aluminum merchandise Oto-san fabricated for the job seems significantly better than a complete lot of plastic. Dosing the air into the consumption plenum is a Bosch electrical throttle physique managed through the Hyperlink ECU.
I actually likes the carbon fiber chassis plaque that mimics the manufacturing unit Toyota one, however with up to date particulars for the G16E-GTS engine, TL70 (Toyota 86) 6-speed transmission and F282 (Toyota Previa) axle.
The solely different modifications wanted to suit the engine have been a number of cutouts on the underside of the fiberglass hood for clearance, and naturally a round opening for the vertical exhaust outlet.
No exhaust on the again signifies that the rear is particularly clear.
The factory-look ‘Toyota Corolla Levin’ decals give a inventory really feel, though the automobile is way from it. The reproduction GR badge and ‘Apex Twin Cam 12′ insignia is just a little trace at what’s occurring up entrance, however there’s no point out of the turbo. I suppose Oto-san will let different drivers discover that reality out for themselves.
Peeking by way of the hatch you possibly can see that the inventory gas tank has been swapped for a racing gas cell. In with the ability to choose the capability and general placement, this improve has allowed Oto-san to dial within the automobile’s weight stability good.
You may as well see the extra reinforcements added to the roll cage, serving to additional agency up the 40-year-old chassis. Up entrance meaning easy gussets to attach the cage to the A- and B-pillars.
Seeing because the automobile is not going to be highway registered, rather than a licence plate Oto-san bent up a sheet of aluminum and added his firm emblem for an additional contact.
As you’d have seen from the view by way of the hatch, the inside is stripped to reveal steel however painted and plated off to cover wiring and different ancillaries.
The inventory instrumentation has been ditched in favor of a mid-sized pill that connects on to the Hyperlink ECU and shows all parameters in a mess of customisable views. All of the change gear has been neatly laid out on all sides of the binnacle so it’s inside straightforward attain.
Taking heart stage within the cabin is Recaro’s wild-looking Professional Racer RMS. This seat might need minimal padding, however I can inform you that it doesn’t come on the expense of any consolation.
Oto-san was particularly happy with the superior job his apprentice did in creating an simply accessible compartment for the electrics. Flip up the duvet and you’ve got full visibility of the cleanly laid out fuses and relays.
So there you could have it, an AE86 constructed for drift however executed in a singular means. I feel the substantial 370Nm of torque the G16E-GTS engine develops goes to make this Levin a blast to drive and possibly ridiculously straightforward to slide round.
I’ll positively attempt to hit up a monitor day when Oto-san lastly takes his GR Yaris-powered Hachiroku out. Nobuteru ‘Nob’ Taniguchi has been a giant fan of the challenge, so hopefully he will get an opportunity to check it out correctly. Till then, an enormous due to Oto-san and his apprentice for opening up the store and this very cool construct to Speedhunters.
