Sercl tuning is providing highest quality oldtimer engine repair. We overhaul all brands of common and rare oldtimer engines of cars, motorcycles, tanks and even ships. Also we have a lot of experience in repairing gearboxes and transmissions. Our company is one of the last in Europe providing such quality services for an affordable price. Mostly the knowledge got lost with the last generation and the companies of our days don´t know any more the specifications and materials used. We are working only with high quality steels or spare parts we tested on composition and hardness. We got the knowledge and even many original materials and parts of those times and pass it on from generation to generation. The pieces which are not available anymore we manufacture ourselves.

See here an overhaul of a German WWII tank in our factory:

Actually we are able to repair and overhaul any kind of old timer engine, till the most modern BMW engines which we tune for international races. But most of our job we love historic engines which we restore piece by piece. We have the most precise tools and machinery in Czech republic. After the repair you have a engine which is running smother and more powerful then when it was new, without additives.
