performance and reliability at affordable prices...
Here at Top Boss we specify, design, build and fit 24V V6 Cosworth engines to suit any requirement or vehicle.
From a basic conversion to all singing all dancing showroom specification starting from £2,000. It can be anything from a Fast Road , Single or Twin Turbo engine. We manufacture locally what we can't buy from manifolds to adaptor plates and hoses plus many more parts which we offer for sale in our SHOP.
For more details on our engine specs please click onto our 'engine details' section. We know a thing or two about Gearboxes too!
