At Fiennes Performance we specialise in not only the precise machining of high-performance engines, but we are also skilled high performance engine builders and rebuilders for specialist road and racing engines. We use only the best quality parts and upgraded components to improve your engine’s power, efficiency and endurance.

Our specialist performance engine builders are highly skilled and qualified, with a combined engineering experience of over 100 years. As a result we offer a range of car performance upgrade services such as a blueprinted engine rebuild, race specification or modern performance car, rebuild for a classic car or bike, performance tuning for fast road and track days and complete performance engine rebuild services.

We can source and supply ancillary parts including uprated water pumps, duplex timing gears and chain sets, vernier timing gears, forged pistons and con rods. Our colleagues at Fiennes Engineering can also manufacture new parts to our specifications. In short, whatever the requirement, the Fiennes group of companies can deliver everything in-house.
