Every Step Matters: Joseph Leggs on Building Precision into High-Performance Engines

• Joseph Leggs, a mechanic, machinist, and engine builder based in Escondido, California, shares how early training and decades of experience shaped his approach to Porsche, Ferrari, and Lamborghini restoration.

How did you get started in automotive work?

California, USA, Aug 11, 2026, ZEX PR WIRE — I grew up around tools and construction. My father worked as a firefighter, paramedic, general contractor, and builder. He brought my brother and me to job sites where we learned hands-on skills early.

“I had tools in my hands by the time I was eight years old. By the time I was ten, I was using power tools under supervision,” Leggs says.

The family also worked on their own cars. That exposure made the transition into professional mechanic and machine work natural. “We worked on our own cars growing up. Transitioning into mechanic and machine work came easy for me because I had already been around it for so long.”

What changed when you started your apprenticeship?

During college, Leggs began an apprenticeship at a Porsche specialist shop. That experience introduced him to a new level of technical rigor.

“That apprenticeship gave me exposure to a level of precision that was completely different. You learn very quickly that details matter,” he explains.

The work required advanced diagnostics, engine rebuilding, and problem-solving under tight tolerances. It became the foundation for everything that followed.

What does your work focus on now?

Leggs specializes in engine building, gearbox rebuilding, machining, and high-performance vehicle service. His work spans Porsche, Ferrari, and Lamborghini models, including both street and race applications.

He has received factory training with Porsche, Lamborghini, and Bentley. That training gives him access to manufacturer-level techniques and standards.

Each project involves careful inspection, machining, assembly, and testing. The goal is always reliability and performance.

What do people misunderstand about engine building?

Many people expect speed. But quality work takes time.

“You can’t rush quality work. Every step matters,” Leggs says.

Skipping a measurement, using the wrong tolerance, or rushing assembly can lead to failure. Each component must fit correctly. Each surface must be prepared properly.

Attention to detail separates a functional engine from one that performs at the highest level.

What advice do you have for someone interested in this field?

Start early. Get your hands on tools. Work on your own car or motorcycle if you can.

Seek out an apprenticeship or technical training. Factory certifications matter. They teach you the right way to approach complex systems.

Learn to slow down and focus. Precision matters more than speed, especially when you are starting out.

What keeps you motivated after all these years?

Every engine is different. Every restoration presents new challenges. The work requires constant learning and problem-solving.

Leggs also values the tangible results. When an engine runs smoothly after a rebuild, the work speaks for itself.

Mountain biking, riding motorcycles, backpacking, and camping provide balance. Those hobbies keep him connected to the same hands-on, mechanical mindset that drives his professional work.

If you do nothing else

1. Start working with tools early, even if it’s just maintaining your own vehicle or bicycle.

2. Seek out an apprenticeship or technical school program in automotive service or machining.

3. Prioritize quality over speed in every task you complete.

4. Invest in factory training or manufacturer certifications to build credibility and skill.

5. Practice measuring and fitting parts with precision before moving to more complex assemblies.

6. Learn to diagnose problems methodically rather than guessing at solutions.

7. Build a network of experienced mechanics and machinists who can mentor you.
