The beginning
Originally founded as a complete restoration company, we handled every aspect of classic car revival, from in-house paintwork and metal shaping to interior retrims and full mechanical rebuilds. It was a family business through and through, known for quality, thoroughness, and a deep love for classic Alfa Romeos.
But as time passed and the world changed, so did we. When Marco’s father retired, it was time for a big decision, and a new direction.



All About
Our Story
What began as a full-scale restoration company has evolved into something even more refined, a singular focus on building the finest classic Alfa Romeo engines in the world. With decades of heritage, craftsmanship, and racing legacy behind it, our workshop is now entirely dedicated to high-performance engine, gearbox, and differential builds, tailor-made for each individual enthusiast.
From concours-level restorations to race-winning machines, our story is one of transformation, passion, and precision.

Marco Hesshaus is the heart and hands behind every engine we build. With decades of hands-on experience and an obsession for mechanical perfection, Marco chose to specialize where his true talent lies: engine building.
Today, every component is assembled, measured, and tested by Marco himself, down to the last screw. No team, no outsourcing, just one man’s commitment to excellence. Together with his wife, Marco runs the business with pride, care, and dedication to each individual customer.
what drives us
We believe that every classic Alfa Romeo deserves to be preserved. Whether restored to its original factory condition or carefully upgraded for racing, our goal is to give these legendary machines a new life, on the road or on the track, built to your vision.
Our mission is to deliver world-class craftsmanship with a human touch. Every project is a collaboration, and every engine is a promise kept.
From Singapore to Sweden, from the USA to Australia, our clients share one thing in common: a passion for keeping legends alive.
