We specialise in A-series Twin Kam conversions and A-Series 7-Port billet cylinder heads. We produced the first commercially available conversion kit and sell all the parts that you'll need to fit a BMW 'K' 8V or 16V cylinder head to your A-series engine.

From our comprehensive build guide, priced at just £19.99, to a turn-key built engine producing over 180bhp, Specialist Components are your one-stop solution. We also offer a comprehensive engine machining and assembly service for all aspects of Twin Kam builds.

We are well known for our innovative new products for the classic Mini, but we also produce an extensive range of high performance billet engine components, engine management systems and billet intake system parts. We can produce electronic systems, billet crankshafts and con-rods in any volume from one-off to OEM quantities. Our range of individual throttle body kits combines the power and performance of our Typhoon engine management system with the patented technology of AT Power's billet throttle bodies.

We specialise in low volume bespoke components at competitive prices and have a global sourcing capability. Contact us on +44 (0) 1953 859785 during office hours (9.00am to 5.30pm Monday to Friday) or send us an email with your requirements.
