There’s no arguing the Lamborghini Gallardo GT3 is no slouch. But the World Time Attack Challenge is a whole different league, and in standard form this factory race car is basically like bringing a knife to a gunfight. To run with the world’s best, it needed serious development—and that’s exactly what Josh and his team at Specialised Racing Solutions delivered, bagging P2 in Pro class on the car’s debut outing.

In this episode of Tuned In, Josh Gardner breaks down his path from car-mad kid to professional mechanic and business owner. He gets into the hard parts of starting a workshop, and why custom builds are never as simple as they look from the outside.

Josh also reflects on the lessons learned from running a business, His work on the Nissan GTR platform and his return to the sharp end of the automotive world with the Lamborghini Gallardo GT3 build—including what it really takes to compete at the highest level at WTAC.

We dive into the nuts and bolts of performance development: turbo selection, installation, and the cooling challenges that come with high-output builds. The conversation also explores advanced engine management systems like MoTeC, the realities of CAN bus integration, and where technology is headed with the use of CAD, 3D scanning and 3D printing in modern performance builds.

Josh is packed with knowledge, and his story—from backyard tuning as a teenager on the family PC to building time attack cars capable of taking on the world’s best—makes for a seriously compelling listen.

Many car enthusiasts have fantasised about a lightweight car with a motorcycle engine swap. After all, what’s not to like about a high-revving, lightweight engine that produces great power and sounds incredible, right?

Reed Stormzand from the YouTube channel Reed Make Car tells us that while the combo can be awesome, it definitely hasn’t been all plain sailing.

In this episode of Tuned In, Reed shares his journey into the automotive world, detailing his self-taught welding and fabrication skills as well as his day job at ZZ Performance.

We discuss his Cadillac ATS-V drag car, ZZ Performance’s involvement in pushing the platform forward, and their pursuit of the ¼-mile world record.

We also cover his CBR1000-swapped Miata, which started out naturally aspirated but is now turbocharged. Reed talks about the challenges of the swap, the intricacies of using a motorcycle engine in a car, and how he learned to tune—first on the stock Miata engine and now on the CBR1000 setup.

Reed never set out to become a YouTube car builder, but he’s built a solid following, and viewers clearly love his projects. His self-taught background, hard work, and willingness to learn by doing stand out as key takeaways. If you want to learn something, just start doing it.
