About us

The Norena cylinder head workshop was founded more than 20 years ago. Driven by a passion for cars, internal combustion engines and motorsport, we have steadily developed our skills, machines and tooling to keep pace with innovation and give you — our clients — the best possible service. We are proud both of our equipment and of the excellent skills of every team member who has been with us from the very beginning.

Over the years the workshop has continuously grown by buying new machines and mastering new technologies and processes. We established a lasting partnership with the Italian machine and equipment manufacturer PEG and have distributed for the Bulgarian and Balkan market since 2021. In 2022 we completely renovated the workshop, expanded the floor area and significantly improved working conditions — a more pleasant environment for us and our clients.

Our strong interest in improving engine performance led us to purchase the first and only airflow measurement bench in Bulgaria — a SUPERFLOW flowbench, which measures and records airflow with engineering precision, faster than any other flow bench on the market. It provides accurate digital readings and control of airflow by automatically measuring test pressure and temperature, then presenting corrected flow data. This lets us calculate and select the most effective settings for your head and block according to your goals and use.

Seeking new heights in developing and improving how your car runs, we concentrated our accumulated experience to launch a new activity — repair of diesel common rail systems and fuel injectors — gaining even more knowledge and skill in the efficient operation of your engine.
