When Dino shot the Weld Techniques Scion FR-S back in 2014, many people online mistook it for another Rocket Bunny-kitted car. That’s not surprising given Kei Miura’s overfender overhaul for the then still new ZN6 FR-S/GT86 (and ZC6 Subaru BRZ) was one of the hottest tuning tickets on the planet.
As you’re about to see in this week’s throwback post, however, the Weld FR-S did not feature Rocket Bunny FRP. In fact, it didn’t feature FRP at all. And that’s just the beginning of this stunning creation… welding equipment
The way I see it, there are two approaches to this whole tuning thing. You have the shops that go out of their way to be the first at everything – they get the latest models and before you know it they have whipped out a full aero kit, slammed the car and outfitted it with some nice wheels ready to display at some big show. That’s great and everything, but then there are others like Johnny at Weld Techniques.
I’ve known this guy for years, and I’ve always been a great fan of his work. This is a man that settles for nothing less than utter perfection – time is irrelevant to Johnny. If a car is going to take a couple of years to put together, he’ll just do it – that’s how he’s managed to build a reputation for himself. Weld has always meant top-level quality in my and many other people’s eyes, and there’s no cutting corners when you’re trying to achieve this level of respect.
It took over one year to get this FR-S ready, and by ready I mean drivable. Much like Johnny, I too took my time with it. We saw it in all its detail at the Tokyo Auto Salon back in January, and I could have shot it after that. But I didn’t. No way! Back then the car’s engine was still being set up so it couldn’t be started, let alone driven. Johnny told me it would be no problem to trailer the Scion to a location of my choice, but I said no. I knew I had to wait, because I wanted to see this thing roll up to the shoot under its own power.
With the sheer time and effort that Johnny and his crew put into this build, the least I could do was put a proper feature together – and in my book at least, that means including rolling shots. I know you guys just wouldn’t have been satisfied if I showed you a bunch of static images of the car either – this thing deserves the full treatment!
Patience is indeed a virtue, and I’m so glad I waited. Because earlier in the week I had a chance to meet with Johnny and dedicate a whole afternoon to his creation. This has to be – without a shred of a doubt – the ultimate and most meticulously-constructed ZN6 on the planet.
And to make the whole car even more special in Japan, Johnny based all of this work on a US-spec left-hand drive Scion, rather than a JDM Toyota.
Cutting corners isn’t part of Johnny’s repertoire, so before anyone thinks it, what you are seeing here aren’t FRP fenders moulded onto a stock body with putty. The entire fender sections are steel, and they’ve been crafted in the old fashioned way – cut out, shaped around a wire frame and slowly hand-beaten to follow the contours that were required.
The bodywork side of the equation was actually a collaboration with Nishino Body Repair up in Ibaraki, where the car stayed for a good six months. Johnny actually taught the guys at Nishino how to go about the whole procedure – something he has done countless times in the past with previous builds. This meant lots of travel back and forth from his shop in Yokohama a couple of times a week to slowly shape the car.
The goal was to create the ultimate FR-S street car – one that combined everything into a well-rounded package: looks, stance, comfort and performance. And you just can’t rush something like this…
You need to take your time to fully take in all the custom work here, because like with a lot of things that just look ‘good’, the subtle details are the ones that took the longest to get right.
Back to the fenders… First up, they had to match the preset widening that was decided upon – something that starts off on the bumper, which was widened with the same plastic the OEM Toyota component is made of – no FRP here. A small indentation highlight was also pressed around the extremity of the line – another little custom touch to set things off. The metal work on the fender itself extends all the way down to the skirt section, which is integrated and again made out of metal. All of this was shaped around the 19-inch Work XSA 04C rims, a wheel that Johnny actually collaborated on with Work Wheels during the design and development process.
The driver’s side of the car shows off the same model wheel, but with an anodized bronze rim section that adds even more contrast against the custom body colour.
Hiding behind those mirror-like spokes are another important detail – the brakes. These are Project µ’s first monoblock calipers, 6-pot items that have been etched with Weld’s logo and signature tribal motif.
That same design is actually machined into the 380mm 2-piece rotors, where they act as slots to help keep the pads clean for optimal performance.
Then there is the rear section of the car, and this is where things get complicated. Look at the car in isolation and you might not even notice it, but parked next to a stock FR-S/86/BRZ/GT86 it doesn’t take much to figure out that Johnny really went full-out to enhance the body’s profile. Pretty much the entire stock rear fender was cut out and reshaped from scratch, taking that stock hip line crease above the wheel arch and making it more evident. Then a parallel curve was created, originating from the actual wheel arch curvature and extending all the way down into the side skirt. Everything you see is metal.
The widened rear fenders perfectly accommodate the 19×11.5-inch-25 offset XSA wheels, much in the same way the fronts where shaped around 19×10.5-inch -19 versions. Laser etching on the barrel is a giveaway that this isn’t an ‘out of the catalogue’ wheel.
The rear gets some pretty serious brakes too. The stock, budget slide-type calipers the FR-S comes with have been replaced with Project µ 4-pot calipers and 355mm rotors with that recognisable Weld tribal grooved pattern again.
The car sits low – as low as anyone would want a street car to sit. Yet Johnny made sure it wouldn’t end up with too much negative camber – rather just enough to balance looks and performance. Those of you that know your rubber will recognise the tyre of choice here: Yokohama ADVAN Neova AD08s with the ‘R’ compound for extra grip.
There is a lot of work that went into making sure the rear bumper had the right sort of look too – specifically the way it tucks in and matches up to the rear fender treatment, and the way it’s finished off with a one-off under diffuser made by Nishino Body Repair. Then there’s the colour of course – a House of Kolor Candy Apple over metallic silver highlights to really make it pop on the hand-sculpted fenders.
You can spend years on a car and make it look incredible, but if there is no substance to it – nothing mechanically special to make it really stand out – well, that would only be half the job done. Obviously there was no way Johnny was going to leave the FA20 stock, nor follow what seems to be the norm with these engines by bolting on a turbocharger or supercharger. In his mind the car came NA, so it should stay NA.
Well hats off to Johnny, because what he came up with is as commendable as you can get. The 2.0L boxer engine might not have all the power in the world, but what it lacks in numbers it makes up for in everything else!
The work started when the heads were pulled off the block for a clean up. The first set of modifications are all about improving response – something an NA engine should have bucket loads of, but something that the stock FA20 doesn’t really have due to modern day engine management and emission controls. So that meant throwing the cheap and nasty plastic intake manifold in the bin and fabricating a one-off crossed item from aluminium piping. Onto this Johnny bolted Toyota AE111 4A-GE mechanical throttle bodies with a set of billet velocity stacks. And check out the XSA RC wheel mounted onto the throttle shaft! 380cc/min injectors from a 1JZ were then mated to a pair of custom fuel rails. The whole set up is controlled by a Vi-Pec ECU, which Trust fitted and then tuned. This was actually the biggest headache of all, as the wiring and setting-up of the quad throttle conversion turned out to be a real nightmare. But Johnny and the guys got there in the end and the car sounds and feels impressive.
The engine dumps gasses into a Trust stainless steel manifold and then onto an Amuse twin-exit titanium exhaust, which enhances that new-found raspiness of the engine and combines it with a deep underlying tone.
For the moment it all adds up to around 210hp, but there is much more to come in the future, like a bump in capacity, hot cams and some serious head work.
Like the rear, the front has received a subtle under spoiler with integrated down-turned winglets on each side to add a finishing touch to the car’s presence.
It’s hard to pick which of the two colour combos work best on the Work wheels, but under the fading late afternoon light the bronze side certainly stood out more to me.
And how can I possibly not say anything about the Voltex carbon rear wing! The ‘swan-neck’ wing stays are something we will be seeing a lot more of in the future as aero makers continue to emulate what is happening in the racing world.
The design interferes less with the air flowing over and under the wing, which generates less turbulence and therefore boosts its efficiency.
To stiffen the two mounting points on the stock trunk lid, Voltex created a moulded trim piece that prevents the lid from flexing – or even caving in- once the wing starts doing its job at speed.
There is absolutely nothing wrong with the FR-S’s cabin, which is precisely why Johnny only upgraded the essentials.
So joining the two Sparco seats – which feature red stitching to match the stock stitching around the interior – is a nice and chunky Sparco suede-wrapped steering wheel. Boom, job done!
We have seen many ZN6s in a variety of flavours since the car’s release, but out all of them, this is the one that has made the greatest impression on me. That’s probably because I respect substance the most – something the Weld Techniques FR-S has absolutely no shortage of!

Killer! Love the engine! Love the way it sits. Wing is big but really works. Nice!
Wow, so much custom work. Amazing build.
with all that engine/exhaust work (looks killer btw) I was expecting bigger hp numbers than 10hp over stock, the rest of the body work looks amazing being all steel!

Lol...a kart would absolutely slaughter this car haha. You guys are so dumb it's cute
I appreciate the compliment! This isn't a hardcore racing website, if anything, it's an automotive lifestyle website, that's why I made the kart comment. Only a complete brainlet would argue that cars are faster than karts. I'm just wondering when we're going to start getting the fighter jet pilots commenting on these articles. Style is subjective, and so is functionality.
If fighter pilots did chime in, it would certainly be dumb to insult them. Especially if they built their own jet engines and planes. Your comment makes a lot of sense. This is the hipster corner of the automotive world. It's a big ask for some intelligent conversation beyond the "vibes" and the "fitment" and the colors of the vehicle. These are the primary focuses here: surface level very very low IQ stuff. It's the newbie / high school crowd. Makes sense why I'm getting the replies I am. It's simply a lower IQ bracket than I'm used to. My mistake. Moving along now...
Ah yes, "vibes." I'm with you on a lot of what you said, but I think you and I know that the automotive realm can really invoke a lot of emotions, hence why people say things like "vibes" in the first place. I think there's lots of art AND science involved in cars which is why a lot of cars on this site are so divisive. F1 cars aren't supposed to be cool looking (though they can invoke emotion), they're supposed to be slipperier than a effing dolphin. Bagged cars (which is 99% of what is on this site) are supposed to look like they are sitting on the ground, that's it. I just wonder why someone who is so much more serious and mature about racing and the car industry is even on this site to begin with?
I’m certainly not going to sit here while people intentionally try to speak down to me. I’m here because people can’t stop making comments like the one you did even when I leave people alone so. When that stops I’ll stop. I can do this forever. You have no idea. It’s funny to me.
Does anyone know what the engine ended up producing power wise, after the cams and head work?
Probably somewhere in the range of 250-260bhp. You aren’t getting huge gains in an engine like this without boost. In an LS heads and a cam can be worth 100-150hp but in small displacement engines like this significantly less. Best to engine swap or turbocharge this engine if you want power. Building it NA is going to be money!!!
As much as you guys clown on karts the modern kart for $5000 packs more punch in a straight line than a 918. And is more challenging to drive than anything featured on this website with a substantial better power to weight ratio and sustained g force in corners. It’s very odd this upsets you guys so much. You’re like people who want to pay 10x more money for a house with 1/10 the amenities and features. Very bizarre how your brains work.
it's a car website though they drive on the road and have air conditioning. and perform an everyday function. i don't argue any of your points but people come here for car content (well i mostly come here for the frank drama)
Well said! No one is arguing that karts are fast, I think most of us know that. Obviously this not a kart website.
Agreed. Though for some reason. I don’t get to have mine? Perhaps people on this website are more feminine and don’t understand non political correct speech. I forget most people on her live in tyrannical countries like Canada etc. Good thing I trained under some of the greatest men to ever race so I am immune to low IQ opinions.
' so I am immune to low IQ opinions'...yet you feel the need to respond to every comment calling you out as the kid-in-a-basement that you really are. 'Perhaps people on this website are more feminine' - WTF does this mean? You keep banding about these misogynistic comments on a regular basis, is it because you don't have a girlfriend or does your gate swing both ways?
Thought police—- shut up and race or….shuddafuqup
My favorite part is how you guys can’t refute anything about what I’m saying about cars but have to resort to personal attacks. So I just respond the same way. Just mirroring you guys. None of you will race. None of you will do anything in person. Just a bunch of feminine men talking behind a computer screen. Lmao. That’s what I mean. Ur getting bullied back and it’s taking 10 of you to handle 1 of men. Hilarious.
Such an alpha male that you won't post your full name because of 'people in the industry' *waves hands mysteriously* so we can't validate all these 'tru facts bro' that you keep coming out with. Give us some race results, or some actual way of validating who you are. Just to clarify what you've stated so far; You're a champion fighter A 'mentor' to many racers Employed by the 'race industry' around the globe Mentored by someone who knew Senna's garbage man or something 'Have' women that could beat other women up In theory should have lots of money yet races a kart and drives an E92 because poor Has incredibly suspect views about women that makes me think a) you've never had a girlfriend or b) you're Andrew Tate Knows everything about building a race car engine and setup and has built many engines Can't engage with anyone without resorting to insults (who was your mentor, Trump?) The only person here getting upset by any of this is you. Your constant posting is a plea for help (which I think you genuinely need) and it seems like you HATE this website yet you constantly post on it, over and over again about how wonderful karting is (I like karting, I do a bit in the off season but it's not my default answer to anything about anything) or how we're all a bunch of 'women' (seriously?). You've even taken to having conversations with yourself just to validate your out-of-date, women hating views. For the record - I'm not turning up at any race track to race you for the following reasons 1) I'd never profess to being a great driver 2) I don't have a massive ego that needs stroking by beating a child on the internet in a grudge race 3) I'm not meeting some utter lunatic that spends more time on here commenting (and probably other websites as well) than doing something a bit more healthy I've seen some of your posts where you come across as knowledgeable and have actually learnt a bit of stuff I didn't know before. Rather than being so aggressive, maybe try to be a bit more constructive - you might feel better for it than shouting at the sky about how wonderful you are...
HMU with a track and some money. Other than that I'm not reading your dumb a** novel. I am who I say I am. If you want me to prove it start talking money. Located in so cal. Will run for $5-10k
1 of me*. Would be a lot easier if you guys each showed up with some money. Line up. And I can smoke all of you in one go for a YouTube channel. I have cars and access to a track and it’s crickets from you guys. If I’m such a fake or whatever should be easy money right? Hmmmm wonder why no takers. Maybe cause you guys are
I usually never like half fender widebody like rocket bunny or liberty walk, but when it molded smoothly like this, it does looks good
Yeah...no one with ovaries care.
Right. No one here cares about speed that’s very clear. You guys are 14 year olds who are all about the vibes and the looks. Noted. Not real men. Little kids who treat cars like action figures.
They care enough to delete the comments and not let them exist. Karts > road cars when it comes to speed. Zero question about that.
Division 1 karts make 100hp and weigh 360lbs. No springs or shocks. No roll bar or seat belt. If you don't understand how hardcore that is you're just a dork.
