In this episode of Tuned In, Jack and Diego share their backgrounds in automotive engineering and their journey into the performance automotive world. They discuss their current roles at Ford, the skills they bring to their YouTube channel Build It Yourself, and the innovative technologies they leverage, such as CAD, 3D scanning, and 3D printing.

The conversation dives deep into the highs and lows of building a one-off V10 engine. From the headaches of welding cylinder heads and perfecting cooling and oil flow to the science of exhaust sound engineering. They unpack machining, camshaft design, and the creative process behind documenting the entire build on YouTube.

Then there’s the bold decision to drop this beast into a 2017 Lincoln Continental, a choice that might not seem obvious to many enthusiasts. With the added challenge of a rear-wheel-drive conversion, it was definitely no straightforward swap.

What they’ve pulled off in their home workshop is nothing short of extraordinary. Blending solid engineering know-how with hands-on ingenuity, their Build It Yourself attitude is truly inspiring.

No matter the stage of a build, most projects reach a point where giving up feels tempting. They demand grit and perseverance—and Karel Silha from Karel S Motorsport’s wild DTM-inspired M4 Time Attack build is no exception.

We first spoke to Karel in 2022, and now he’s back to share what it really takes to shake down and test a home-built car of this caliber. Believe it or not, it all started with a toy car that Karel scanned and scaled up using CAD

👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip

In this episode, we explore the engineering details behind the build. Karel explains the challenges of mounting a massive aero package capable of generating serious downforce. He highlights the practical difficulties of high-performance engineering in a garage environment.

Karel also shares how he’s utilised modern tools like CAD and FEA to optimise the design. We talk through his experience testing on KW Suspension’s seven-post rig—fine-tuning the suspension for low-speed mechanical grip and managing the immense downforce at high speeds.

We discuss the complexities of engine management with turbocharging and individual throttle bodies (ITBs), the importance of on track testing versus dyno calibration.

Despite the technical challenges and the emotional toll, this episode is far from bleak. Karel’s journey is incredibly inspiring and he’s optimistic that 2025 will finally be the year this insane build shows its true potential.

Designing an elaborate engine block or cylinder head in CAD is one thing, but actually manufacturing that design is another challenge altogether. In this video, we talk with Gerry from Crest CNC about what it takes to turn complex billet and cast designs into reality

Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip

Gerry handles CAD design at Crest CNC, creating engine blocks, cylinder heads, and the tooling and fixtures required to manufacture them efficiently. He explains how his early career as a toolmaker led him into CNC machining, CAM programming, and then full-time CAD design. During his time in the UK, he worked at JCB’s engine division, gaining critical experience in engine block and cylinder head design fundamentals.

For their cylinder head development, Crest CNC work closely with third-party experts such as Cylinder Head Specialists to optimise port and combustion chamber geometry. They use traditional flow bench testing and 3D scanning to bring these designs into CAD before finalising them for manufacturing.

Gerry also discusses design for manufacture considerations, often called DFM. Whether working with billet parts or cast parts, understanding machining limitations, tooling aspect ratios, taper angles, and draft requirements is essential. Design for manufacture ensures that parts are not only functional but also practical and cost-effective to produce.

If you want to learn more about how advanced billet and cast engine components go from idea to finished product, or how companies like Crest CNC and Cylinder Head Specialists push high-performance design, this interview is packed with insights you can apply in your own engineering or fabrication projects.

Most people overlook the third-gen Toyota MR2 (MR-S), but Justin from Close Enough Racing has spent years turning his into a proper grassroots weapon.

From a modest 1ZZ track car to a 450kW turbocharged 2ZZ build with APR widebody aero, a Jubu Racing close-ratio gearbox, and Porsche brakes, this is a fully developed MRS that competes on the world stage at World Time Attack Challenge.

You’ll learn how Justin and his mates handled the powertrain setup, aero evolution, and suspension development while working around the MR chassis’ limitations and strengths.

The car features a Gen 2 Garrett G35-82R turbo, factory-based poly bushed mounts, and a 3582R-based turbo system pushing 35 psi through a built 2ZZ engine. The team worked with brands like CMS Performance for tuning, APR for aero, Shockworks for suspension development, and even adapted Porsche Boxster calipers using custom dogbones.

Despite not being professional engineers, this group of friends put together a car that can compete with far more expensive, professionally built competition.

If you’re building your own track car and want to see how to combine smart part selection, testing, and a bit of ingenuity to go fast on a budget, this one’s worth your time.

Why don't OEMs tune for the maximum reliable performance and what's all the fuss about over emissions compliance in the United States 'street legal' modified car scene?

Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-in

Emissions compliance might not be the most exciting topic, but if you're tuning a street car, ignoring it could land you in serious trouble. We're joined by Chris Mountain from ‪@cobbtuning‬ to break down how emissions regulations have changed, what CARB (The California Air Resources Board) EO (Executive Order) certification really means, and how you can still make large power gains while staying '50-state' legal within the regulations the EPA (Environmental Protection Agency) has developed and enforces (like it or not).

Covered during this SEMA show interview is why OEMs tune for lambda instead of maximum performance, how hardware mods like intercoolers and turbo upgrades affect emissions, and the rigorous (and expensive) testing companies like COBB are now going through to ensure compliance. Plus, find out how you can achieve 20-30% power gains without risking fines or legal headaches.

If you're modifying a street car in the USA and need to keep it legal, this is a must-watch.
