There’s something undeniably special about the sight—and sound—of a classic Porsche 911 sliding through gravel, rooster tails of red dirt fanning behind it. This year’s 2025 Bunbury Rallysprint saw Ktec Autohaus make a triumphant return to the stages, teaming up with 2023 WA Rally Champion Daniel Gonzalez in an air-cooled 911 that turned as many heads as it did corners.
For Ktec Autohaus, known for its precision engineering and passion for performance, the event was more than just a weekend in the dust. It was a celebration of pure driving—the kind that connects car, driver, and surface in a way that modern machines rarely replicate. “Some cars just feel right at home in the dirt,” said the Ktec team, “and the classic 911 is definitely one of them.”
The combination of Gonzalez’s rally-winning pedigree and Ktec’s meticulous preparation made for a thrilling outing. Despite fierce competition and unpredictable surface changes throughout the day, the pair demonstrated why experience, balance, and mechanical simplicity still have a place in the sport’s modern landscape. The unmistakable wail of the flat-six echoed through the Bunbury countryside, a reminder that rallying isn’t just about lap times—it’s about character.
Wanneroo Raceway came alive last weekend as Ktec Autohaus turned the iconic Western Australian circuit into a proving ground for some truly special machinery. It wasn’t just another track day — it was a showcase of passion, precision, and international collaboration.
Two of Ktec Auto’s long-time clients flew in from Singapore, eager to work alongside the team for an intensive afternoon of testing and development. The goal? To refine and finalize the setup on a project that’s already rewriting the rulebook — the world’s first 997 RWB Cup Car.
For months, Ktec’s engineers have been carefully blending the raw edge of Porsche’s 997 GT3 Cup pedigree with the unmistakable flair of RAUH-Welt Begriff (RWB). At Wanneroo, all that work came together.
Dialing in Perfection
Under the Perth sun, the Ktec crew got to work — analyzing data, tweaking damper clicks, and refining geometry settings to squeeze out the perfect balance between aggression and composure. With Sepang Circuit on the horizon, this shakedown was all about making sure the car performs as beautifully as it looks.
“Getting the suspension right for Sepang is crucial,” said a Ktec engineer trackside. “It’s a very different surface and climate compared to Wanneroo, so today’s data will guide the final adjustments before the car ships out.”
Each session saw subtle evolutions in handling — sharper turn-in here, flatter mid-corner stability there — all culminating in a setup that delivers both pace and confidence.
A Glimpse Into the Future
The day wasn’t just about one car. Ktec also rolled out a freshly acquired 997.1 Cup Car, a pure race-bred machine soon to undergo a transformation of its own. This chassis is destined for Singapore, where none other than Akira Nakai, the legendary founder of RWB, will work his magic in 2026.
Seeing the car in its raw Cup configuration provided a tantalizing preview of what’s to come — the union of Porsche’s motorsport DNA and Nakai-san’s visceral design language.
Bridging Continents, Building Legends
From Perth to Singapore and beyond, Ktec Auto is redefining what collaboration in the high-performance world looks like. Their hands-on approach, combined with deep technical knowledge and global partnerships, ensures that each project is more than just a car — it’s a story of craftsmanship and connection.
As the sun set over Wanneroo and the last of the Cup cars were loaded back into transporters, one thing was clear: this was more than a test day. It was the next step in Ktec Auto’s ongoing journey to push limits — both on track and across borders.
How does it feel? Step inside KTEC and you’re greeted by a sight that would make any aircooled enthusiast’s heart skip a beat: a workshop floor lined with stunning Porsche and Volkswagen classics, all wearing shades of blue. From Riviera to Gulf, from soft pastel tones to deep metallic hues, each car carries its own story—yet together, they form a breathtaking display of aircooled heritage.
For decades, KTEC has been at the heart of Western Australia’s aircooled scene, building, restoring, and maintaining Porsches and Volkswagens long before they became the cult icons they are today. With a reputation forged on knowledge, craftsmanship, and genuine passion, the team has earned its place as one of the most trusted names in the business.

Whether it’s sourcing hard-to-find factory parts, carrying out a meticulous engine build, or undertaking a full nut-and-bolt restoration, KTEC brings an unrivalled depth of expertise to every project. The workshop has seen it all—barn finds reborn, concours winners perfected, and daily drivers kept on the road for generations.
But on this particular Monday, the mood is extra special. The collection of blues under the shop lights is more than coincidence—it’s a reminder of the timeless allure of aircooled design and the way colour can amplify character. Whether it’s a split-window kombi, a beautiful, original SC in Arrow Blue. or the race-focussed RWB with it’s famous blue livery, they’re all loved and cared for by the KTEC team.
At KTEC, days like this are part of the story. They’re proof that the workshop is not just about turning spanners—it’s about keeping history alive, one car at a time.
So if you’ve got aircooled blood in your veins and need advice, parts, or a trusted team to handle your pride and joy, don’t settle for guesswork. Speak to the people who have the runs on the board here in WA. KTEC knows aircooled like few others, and Blue Monday is just another reminder of why.
The Idlers 12 Hour endurance race at Twin Ring Motegi has become one of the most anticipated fixtures on the Japanese grassroots motorsport calendar. Known for its demanding format, extreme summer heat, and eclectic mix of competitors, the 2025 running of the event marked a new chapter for RAUH-Welt Begriff (RWB). For the first time, Nakai-san entered a fleet of modern Porsches—two 997 Turbos and two 997 GT3s—signaling a bold evolution beyond his iconic air-cooled builds.
Preparation began at the brand-new RWB headquarters in Nikko, where the team assembled in the days leading up to the race. Long nights were spent fine-tuning the cars, dialing in setups, and ensuring the 997s were ready for the grueling demands of endurance competition. Testing took place on the technical mountain passes near the workshop, where the cars were pushed hard through elevation changes and tight switchbacks to refine balance, response, and cooling systems.
The KTEC team, one of only a handful of authorised RWB builders worldwide— were once again invited to race. Having forged a reputation for precision Porsche builds and long-standing ties with Nakai-san, KTEC joined the team at Motegi, bringing both technical expertise and the pride of carrying the Australian flag into one of Japan’s toughest endurance contests. Their collaboration underscored the global nature of RWB today: a tight-knit family spanning continents, united by a shared passion for Porsche and endurance racing.
When race weekend arrived, Motegi delivered its trademark brutality. Track temperatures soared into the high 30s, placing enormous strain on engines, brakes, and drivers alike. The 4.8km circuit, with its mix of long straights, tight corners, and punishing braking zones, demanded absolute consistency and reliability over the twelve-hour contest.
Despite the heat, the RWB 997s ran faultlessly. The Turbos delivered relentless pace on the straights, while the GT3s balanced speed with endurance-friendly handling. Across countless driver changes, fuel stops, and tire swaps, the cars never faltered. Strategy was clean, pit work was precise, and the drivers executed without mistakes.
By the time the checkered flag fell, all four RWB entries crossed the line—twelve hours of racing completed without a single major issue. For RWB, it was proof that Nakai’s move into modern water-cooled platforms could withstand the unforgiving test of endurance racing. For KTEC, it was validation on the international stage, proudly representing both Australia and the growing RWB global network in one of motorsport’s most unique events.
The Idlers 12 Hour remains one of the purest expressions of endurance racing—a place where privateer teams can share the grid with legends, where perseverance matters as much as outright speed, and where the paddock feels like family. For RWB, 2025 will be remembered as the year the new generation cars proved themselves at Motegi. And for teams like KTEC, it’s a reminder of what’s possible when passion and precision meet at the highest level.
For anyone who has ever imagined competing at Idlers, there’s only one way to know what it feels like: get on the grid. Next year, the opportunity awaits.
Tucked away in a quiet corner of Tokyo sits a name whispered with reverence among Porsche enthusiasts – Promodet Komine Engineering. For those who speak the language of air-cooled flat-sixes, this is sacred ground. On our recent KTEC trip to Japan, we were lucky enough to step through its doors – and into the beating heart of Japan’s Porsche tuning culture.
The air inside the workshop was thick with history. Half-built engines sat like sculptures, precision-machined parts neatly lined the benches, and in every corner there was a car with a story to tell. This is the birthplace of some of the most iconic Porsches ever to roll onto Japanese streets – and beyond. Komine-san’s touch can be found on Nakai-san’s legendary RWB builds Stella Artois and Rotana, machines that have become poster cars for a generation. And then there’s the original Midnight Club 930, a car that carries the weight of street racing legend on its shoulders.
Komine-san greeted us with the warmth of an old friend. What followed was an afternoon of pure automotive storytelling – discussions about engine breathing and cooling, suspension geometry, and the delicate balance between power and reliability in an air-cooled build. Every word revealed the quiet obsession and relentless pursuit of perfection that has made Promodet a global name.
We left feeling like we’d just been given a rare audience with the keeper of a secret craft – someone who has spent a lifetime refining not just machines, but a philosophy.
A huge thank you to Komine-san and the entire Promodet team for opening their doors and sharing their world with us. This was more than a workshop visit – it was a pilgrimage.
