Here at QED Motorsport, we have over 40 years of experience developing, manufacturing and supplying race and performance engine tuning parts.

We cater specifically to the Lotus-Ford Twin Cam, Lotus 900-Series, Rover K-Series, Opel / Vauxhall XE (C20XE) and Opel / Vauxhall Ecotec (X20XEV), focusing on various forms of clubman motorsport including hill climb, sprint, autograss, rally and historic racing. Many of the staff here at QED, past and present, have competed in numerous championships and have collected a lot of trophies along the way. We also proudly sponsor various categories in the HSA Speed Championship. Sufficed to say, we have a lot of experience with these engines!

Whether you're looking to prepare an engine for competition, finish off a restoration project, re-build that one in the corner which threw a rod, bolt on some go-faster bits or simply fix a pesky oil leak that's ruining your score at concours events, we've got it covered! We maintain a comprehensive range of UK manufactured parts for both road and competition use - some of which are exclusively supplied to us here at QED Motorsport Ltd. and others which have been developed and manufactured in-house, to exacting standards. We supply many well known engine builders and parts suppliers, have a large worldwide customer base and over the years have built a reputation for quality and service, so you can buy from us with confidence!

Feel free to browse around our online store and if you have any questions or comments, why not drop us a line? We're always happy to help.
