Too Much Is Never Enough: A 1,294whp Supra

Think Gatebil and it’s not hard to conjure up thoughts of mutant creations with mind-blowing four-digit horsepower outputs being thrown sideways at speed. And there’s a good reason for that, because when it comes to building cars – especially crazy-fast cars with outside-of-the-box thinking – Scandinavia does it like no other.

But amongst the mayhem you’ll find cars like Tobias Andersson’s 1993 Toyota Supra RZ – a well-known Swedish creation from the garage of Gatebil regular Peter Björck, aka ’Bjørcks Busbil’, aka the builder/owner/driver of a certain Volvo 245 wagon. Not only is the JZA80 one of the cleanest street-driven Supras you’re ever likely to come across, but having stamped its mark on the strip with an 8.82-second pass with Peter at the wheel, it’s probably one of the quickest too.

It doesn’t take a genius to work out that moving a fully-loaded Supra down the quarter mile in less than nine seconds takes an almighty amount of power, and as you’ve probably worked out by the title of this post, this one has rather a lot of it. Interestingly enough, when Peter built the Supra he was never chasing a specific number or had a particular horsepower goal in mind, but through the evolution of its factory-fitted 2JZ-GTE engine a staunch 1,294whp is where it’s ended up.

If that number wasn’t impressive enough in its own right, the fact that Peter built the car himself in his garage with no previous experience with Toyotas – or the venerable 2JZ for the matter – is testament to the achievement here. Of course, being an aircraft technician and obviously someone with an eye for detail has certainly helped the cause.

And there are details aplenty, whichever angle you view the car from. Peter originally imported the Supra from Japan, and thanks to one of its previous owners it had already been subtly upgraded with a Border front bumper, Bomex side skirts and 98-spec headlights and tailights. The Euro-spec bonnet is one of Peter’s small touches, as is the left-hand-drive conversion – something that he didn’t have to do, but wanted to.

The Work Meister S1 alloys also came with the car from Japan, and at 18×10-inch and 18×12-inch front and rear respectively they’re a perfect fit. The wheels and their Yokohama AO48R semi-slicks see street and track duty, with Weld wheels and drag-specific rubber getting swapped on for quarter mile jaunts. On those days a Simpson parachute is attached at the rear too.

For Peter and now Tobias however, the Supra is primarily a street car – and the further you look into it the clearer that becomes. Albeit a street car with the ability to handle much more pressure than its 30psi Auto Meter Pro-Comp gauge can read.

Ever since the Supra was built in Sweden, its 2JZ-GTE has been through a few different guises, each time becoming more and more powerful, until it looked like this. According to Peter, thousands of hours were invested into the creation of this car, and gazing into the jaw-dropping engine bay that’s nowadays awash with polish and carbon fibre, it’s not hard to see where a lot of his time went. I love the fact that something can be completely over the top, yet thanks to an almost monochromatic finish understated at the same time.

As impressive as it looks on the outside, within the walls of the straight six is where most of the work has gone on. Custom CP forged pistons and Carillo rods feature, as do Crower cams and oversized valves in the JB-Engine race-prepped DOHC 24-valve cylinder head. Those beautiful adjustable cam gears are Peter’s owned handiwork, and one of a long list of custom parts that he casually knocked up at home.

Given its dimensions, it’s hard to miss the turbocharger – a rather large Garrett GT47-88 sitting on custom high-mount manifold that can also be credited to Peter. He’s also responsible for the intercooler pipes too, which run to and from a sizeable Blitz front mount core.

A 60mm HKS GT wastegate is employed, and working in conjunction with a Vipec V88 engine management system takes care of boost control. There are gear-dependent pressure presets, and a dash-mounted switch to select between low and high settings. At the upper limit, a staggering 3.15bar (46psi) gets blown into the 2JZ.

To satisfy the engine’s need for fuel at such times, Peter pieced together a pretty innovative set up that runs two distinct systems – one for regular pump gasoline, and the other for E85 biofuel. Under high load, a boost pressure sensor switches over the supply from the gasoline tank, Bosch Motorsport 044 pump, AN6 lines, Fuelab fuel pressure regulator and Siemens 670cc injectors, to the E85 system with a completely separate set of components. That is another tank, AN10 lines, Fuelab Prodigy pump, a Weldon fuel pressure regulator and Siemens 2340cc injectors. Because of E85′s high octane content and cooling properties, the biofuel injection is well suited to the application, not to mention a nice advertisement for Peter’s part-time online parts shop which specialises in this type of gear.

Peter built the custom plenum chamber/intake manifold too, and the dual fuel rails that supply 12 injectors in total. On the ignition side of the equation an EMS-triggered M&W PRO-16b CDI unit is utilised, along with the 2JZ’s factory coils.

Exhaust gases exit via a handmade dump pipe into a four-inch system with two mufflers.

As far as 2JZ street engines go, they don’t come much harder tuned than this. I’m not sure if it’s the world’s most powerful, but I don’t think there’s any questioning of it being right up there. It’s absolutely a work of art.

Considering the monster motor has been built around a standard block and still uses the factory crankshaft, it’s a pretty good testament to Toyota’s 2JZ-GTE hardware. Likewise, the Supra’s original six-speed Getrag V160 gearbox is yet to buckle under the pressure. The rest of the driveline has been uprated however, now featuring a Toyota Racing Development limited slip differential, Svea driveshaft and a Tilton triple-plate clutch complete with an EMS-controlled hydraulic clutch flow control valve to limit shock on engagement.

Inside the Supra there’s a nice balance between form and function. The rollcage for example, while somewhat of a necessity in car that’s able to cover the quarter mile as quickly as this one, seamlessly integrates into the space and allows full use of the factory dashboard. Low side intrusion bars that run between the A-pillar bars and the main hoop mean there’s no need to contort your body to get yourself in and out of the seats.

Built by Peter of course, its simple design has allowed for all of the factory trim to be retained.

In fact, trim is retained right the way through the cabin into the rear hatch area. Running a full interior like this – complete with air-conditioning, electric windows, carpet and a DVD audio system I should add – might go against the grain of a car built for outright acceleration and speed, but any extra weight it carries is most certainly offset by those wild horses running rampant in the engine bay. In highly modified machines, comfort is so often sacrificed for performance – but it’s most definitely not in this case.

Although these four unlabelled switches mounted in the centre console aren’t factory, they blend in nicely with their no-nonsense surroundings. One triggers the line lock valve for pre-stage burnouts, one turns on the data logger, one switches between high and low boost settings and the other toggles the fuel gauge between the gasoline and E85 fuel tanks. Neat huh?

With the amount of g-force the car is capable of generating, a decent pair of race seats were required of course.

And the same went for something grippy to hold onto. Tightly.

Without losing sight of what this car is – and a rocket with four wheels seems appropriate – on its low boost setting of 0.8bar (11.7psi) the Supra has proven to be a remarkably streetable machine regardless of whether it’s blurring scenery on the motorväg or creeping along a high street.

There’s no denying it looks every bit the part too: the inimitable factory lines of a Japanese performance icon, squat on a fat set of classic JDM rims. The perfect compliment to the supercar-decimating firepower that hides under its hood, don’t you think?

Having created an ultimate interpretation of the Supra, I’m sure it would have pained Peter immensely to part ways with this machine, but at least he can take comfort in knowing that in handing over the keys to Tobias it’ll be treated in the way it was built to be. Peter’s still got his 2JZ-powered Volvo 245 wagon to keep him happy and a new project that he’ll be shipping back from Dubai – where he’s currently based – to Sweden when the opportunity arises. That’s destined to be another ‘Busbil’ build of course, but in starting with a Lamborghini Gallardo Superleggera who knows where it’ll go.

I wouldn't say this thing is the fastest/most powerful Supra in the world.  I personally own one that makes 1050whp and I'm no where near the top of the list, probably not even in the top 10% of US Supras.

 

What amazes me is that he is still on a Vipec V88.  And the dual fuel systems seem kinda pointless unless the E85 is like $10/gal over there.

 

This car is beautiful though, very tastefully modded.

Whenever I see these cars my mind goes to the little gal that drove the cosworth sponsored pink subi that ran 170 MPH, and something like a 7.75 range E.T. Thru the quarter mile. She would embarrass a lot of these boys. That little subi was fast.

what is the point of having so much power in a daily driver yes it does 8.82 down the quarter but why not then just turn it into a full on track only drag car cause hes never going to use all that power on the street and if he does one day his license will be shredded not to say the cars bad but really do you need that much power on the street

Amazing build! I really love Supras and wish there were more of them on speedhunters, but this i certainly worthy of this feature. The only Supra i know of that might be even more crazy, is KDW's Supra from Denmark. Made 1300hp on pump fuel and mindblowing 1700hp on race fuel. Unfortuneatly the story goes that the car was stolen by someone that was interested in purchasing it, and shortly after KDW went to prison for something unrelated. I have no idea what happened to the car after that. heres a video of it from around the time the car was newly built. http://www.youtube.com/watch?v=t6AXyglx5X4

I have to admit that I too usually have a bit of a "oh another 1000hp Supra" feeling when it comes to most. But I actually really appreciate this build. Something to do with the performance as well as the mind-blowing craftsmanship and attention to detail. Awesome build.

I've always loved the look of the later model Supras, for some reason all the 1000hp supras I see are styled and really well built. I can't actually recall seeing one over 1000hp that was distastefully modified. Have always wanted to own one, such a bruiser. Theres an 80 year old woman who drives a jet black one thats slightly modified around the town I live in. Every time I see her I want to walk up to her and buy her car. She got it new in 98 and has kept it pretty much stock. Love these cars!

Awesome article and car! SH should definitely have more Supras!

 

As Chris said, it's easy to be jaded with Supras due to the amount of crazy builds there are out there. However, the craftsmanship and time put into this car alone deserves some serious recognition. I've been following Bjorck since 2006 and this car has been epic since day 1. 

 

Wish Bjorck the best of luck with his new endeavors and hope the next busbil will be awesome too!

Impressive build but I wonder if I am the only one to get a little jaded when I see monster Supras like this with 1000+hp. Seems like I had seen similar builds almost a decade ago. Not saying this is lame in any way, that is a grotesque amount of power and wherever it goes, it probably would result in as many shitstain 11's as there would be rubber 11's laid down. Having said that, I cant help but sorta blend this in with all the other monster Supras I've seen or read about over the years and cant really find much that is distinct enough to separate it. Although it does look much more of a sleeper than you would expect so that is cool, especially with retaining a mostly stock interior. And bringing the aviation level of detail and attention to the build probably contributes to the quality and streetability. I am torn. Anyone else? Maybe with the current trend these days, my brain just expects the exterior to be as wild as the drivetrain, a la Ben Sopra and crazy clamshells and wings, or liberty walk or RWB widebodies. But then again thats the current trend in Japan and of course the Swedes are all about sleepers. I need a coffee, my brain is going haywire with these rollercoaster of emotions and thoughts

 @DemonFD Might not be the fastest, But its for sure on top10 Supras with full interior and 6speed. Ran 8.82 @  268km/h on 402meters. A gallon of e85 is around 6 USD as SWR said.

SWR

 @DemonFD

 Nah, the E85 is just about $6 a gallon. Close to half the cost of premium unleaded 98 RON (aka US 93) octane.. I guess he has that for ease of starting and toddling about on cold mornings..

Because it's fun! My personal opinion from all the cars I've got to drive over the years is that the most HP on the street you can practically use is about 350-400whp. But just like the night I got to take out my friends 2013 CL63 AMG....what happens when that guy on the blue R6 pulls up next to you and you're a young dude in a brand new 600hp sports car. The light turns green, you both mash the gas and 10-12 seconds later you are literally laughing so hard you can't recall another time you had as much fun. People build these kinds of cars and drive them on the street because it's mental and it's one hell of a laugh. 

 

Why drive a Veyron around on the street...you're never going to do 253mph (unless you're that one guy who did and got arrested). It's just fun to do and life is short. May as well daily drive an 8 second supra if you have the means to one day.

 @Hotcakes The fact that this one isn't putting down 1300 hp constantly makes it attractive. It's streetable with 35 less psi then hi boost lol. And the Work Meisters do it for me also lol.

@SWR @DemonFD Are you telling me that you don't have A100 (100 octane) in every gas station? Cuz here in Europe we have A95 (octane) as the regular fuel.. E85 wow....

Having 4WD in a customer car - Mitsu 3KGT VR4 - I can say that you can easily have a package like this and handle 800 whp fairly easily...  more than that and you're into going "shopping cart" when it pulls sideways on all fours...

 I believe he's referring to the low boost/high boost toggle switch. Article refers to the car being perfectly streetable at 11.7 psi.

@kamenkachev@SWR@DemonFD Yup, highest octane gas we have in Norway is Shell V-power Nitro 98 RON at $3 per liter.. used to have 99 V-Power but the idiots discontinued it.
